Hi I have the designer handbook of Protel99SE. I submit that simulator, signal integrity and PLD is poorly documented. Wolfgang Geier JUMPtec AG [EMAIL PROTECTED] 19.11.2001 17:26 Please respond to "Protel EDA Forum" To: "Protel EDA Forum" <[EMAIL PROTECTED]> cc: Subject:Re: [PEDA] Protel usage I'm curious. How many upgraded to Protel 99 SE and thus do not have the "Protel 99 SE Designer's Handbook", and how many people do have it? How many of the people with the Designer's Handbook feel the simulator, signal integrity and PLD are poorly documented? The reason I ask is that at the last job we upgraded to 99Se and the help files sucked for figuring out how to use the new features, but at this job we bought Protel new and the Designer's Manual is actually quite a bit of help. I just wish they had put the Designer's Handbook into the help files, so I don't have to go get the manual back from the other engineer everytime I can't remember something.

Re: [PEDA] Protel usage
I find the Print mgr very useful & reliable; you can carry PPC (Print mgr) files forward from one design to the next & reuse them, so I'm not sure what you mean about having to repeat the setup. My one complaint is that it insists on rebuilding all the previews whenever the slightest change is made. Similarly, an existing CAM mgr control file can be reused in a new design. -Original Message- From: Brooks,Bill [mailto:[EMAIL PROTECTED]] Sent: Monday, November 19, 2001 1:54 PM The print manager is sucky... and buggy... and makes me repeat the setup steps over and over with every edit session I set up...

My detailed instructions were largely based on the requirement that the net names needed to be obfuscated as, is common with a clear schematic, the net names themselves may carry significant IP. To mask all the possible IP from the PCB it is necessary to remove the net names and substitute generic netlister/synchroniser allocated names. The netlist is necessary in some circumstances as the bug/problem/issue/feature being demonstrated may require a netlist. In the case of a completed board the netlist can be generated from the copper as per the above command sequence. This is not the case in an incomplete board - to be more specific - in a board that is not fully routed.

It is practically impossible to *fully* test a large memory chip because there can be data-sensitive errors. I.e., when this cell is 1 and that cell is 0 and this row over here is all 1s, and then one writes such and such to a cell, there is an error. Especially dynamic memory can be vulnerable to this. Last time I remember running memory tests, there were options to test them six ways until Sunday. It was very time-consuming. On the one hand, the computers were slow by today's standards; on the other hand, the memory chips were much smaller (i.e., fewer cells). >At any rate... if anyone is interested in FULLY testing your >system memory, you can get a great FREE memory test program at: > >http://www.teresaudio.com/memtest86/ Thanks for the URL!

If the board has all the footprints, i.e., there is a pad for every node in the net list, it is simple to load the netlist, globally edit all the comments to something innocuous, then dump the net list. It will not contain any of the original part type information, just reference designators, footprints, and nets.

You can't MOVE a pad or >hole with reference to the part, however. While I generally agree with most everything Mr. Elson wrote, this particular piece of information is incorrect. First of all, you can edit the position of any component primitive to a new location, or you can pick it up with the mouse and move it. All you need to do is to turn off primitive lock in the component edit screen. With lock off, you can also delete primitives. Perhaps you might want to modify a component legend outline to fit a reference designator in. Natually, it is advised to keep primitives locked except when you really want to work on them. Further, if you ever update the PCB from the library containing the footprint in question, it will return the part to its original state. So it might be safer to create a modified footprint in a special library (you don't need to keep it, just make sure that the name is unique). You can also add primitives with the new tool under Tools/Change. You can also edit even locked component pads in the spreadsheet.

Not to continue this off-topic thread too far, but they only test the memory chips for a few seconds in each condition (hot, cold, etc.) and with the number of bits in a chip, it has to be a cursory test. The noise conditions present on the chips after they are mounted on the SEMM/DEMM module may not be ideal in all systems, either. > At any rate... if anyone is interested in FULLY testing your > system memory, you can get a great FREE memory test program at: > > http://www.teresaudio.com/memtest86/ > > It will exercise all your memory, CPU cache memory, etc. If > there's a memory bug, it will almost certainly find it.

Re: [PEDA] Protel usage
No not currently. I'm a one man shop. PCB is between 5 and 10% of my workload. However before this year, I worked in a small company with 5 engineers and we all shared 2 seats of Protel. (not at the same time) We checked all regular source code into SourceSafe and also checked in Xilinx source and project files, Protel files, Cadkey files, and any other files that pertain to building an assembly or product. It worked great. One IT guy backed up the server every day, and our data was backed up period. We did have to screw around with collecting data from everyone's drives or worry about a tape backup that partially failed because one person turned off his computer.

Re: [PEDA] Copper Calculations
Steve and the Forum, There appears to be some confusion in several of the posts in response to your original question, and I believe that I can clear up some of that confusion. Most of the "tables" or "calculators" available today have their basis in the old MIL STD 275 tables which plotted "current" in amps against "rise in temperature above ambient" in degrees C for a given "thickness" or weight of copper on a PC Board. These tables can be found today in IPC-2221 on page 38 as Figure 6-4. There are numerous other versions of these "tables" and also many "calculators" available today which offer basically the same information. What appears to be the basic misunderstanding in the posts in reply to your question is that they seem to be talking about a given amount of current through a given conductor size of a given layer thickness at a given temperature. This is not the correct application of the charts or calculators. The results are not to be viewed at a specific temperature, but rather viewed as generating additional heat and "adding" a certain amount of heat to the "ambient" or normal temperature. That means that if the normal temperature in a given area of the PCB is 25 degrees C, and you can tolerate an additional 10 degrees C temperature rise in the copper conductors in that area due to current being passed thru them, then such and such a current can be passed thru such and such a width of such and such thickness of copper in that area. In other words, passing X amount of current through a conductor of Y width and Z thickness will cause the conductor to rise so much in temperature. Please remember that only the thickness of the copper counts in these current calculations, since solder is only about 16% as conductive as copper. There have been a number of recent related posts to the "PCDList" listserver forum lately, and much useful related information may be gleened by looking at some of those archives. The "list" can be accessed via the PCDMag site at: ==> http://lyris.mfi.com/cgi-bin/lyris.pl?enter=pcdlist Hopefully this clears up some of the confusion. JaMi Smith Optical Crossing Inc.

Yes, but that's not the same as when they are on the motherboard. All kinds of variables come into play: the memory chip timing, the front-side bus (chipset) timing margins, how well the impedances are matched and terminated, the supply voltage stability, how well the memory bus is shielded from interference from other sources, etc. Cheap PC motherboards have been known to exhibit problems before. I seem to recall some years ago during the tantalum and ceramic capacitor shortage that some cheap motherboards cut down on the recommended bypass caps. The result is that the PC would work for about 3-6 months and then start flaking out, as the caps dried out. Then there were the reports of some Cyrix-based motherboards burning a hole in the PCB because of inadequate cooling at high clock speeds. Your (original poster) problem may not be memory. But I thought it might be a possibility. As a hardware designer, I have to debug my own and other's designs. It's like a Sherlock Holmes mystery to be solved sometimes. "When you have eliminated the impossible, whatever remains, however unlikely, must be the culprit" (paraphrased). I have always been able to find the causes of problems using this philosophy. Well, causes of electronics problems anyway.

Re: [PEDA] Protel usage
I'm with you, Tony. You couldn't pay me to go backwards into the old separated file method.

Actually, the high speed digital testers employed by the memory manufacturers FULLY test memory modules over their rated speed and voltage ranges. Usually any problems that occur after the module leaves the factory are due to handling, installation or motherboard related issues (timing, voltage, noise, etc.) Memory chips themselves are 100% parametrically tested after they are packaged since the manufacturer is in the business of selling specified, functional chips. At any rate... if anyone is interested in FULLY testing your system memory, you can get a great FREE memory test program at: http://www.teresaudio.com/memtest86/ It will exercise all your memory, CPU cache memory, etc. If there's a memory bug, it will almost certainly find it.

[PEDA] Removing IP from PCB (Ex: Protel's Good/Bad points ...)
On 04:29 PM 19/11/2001 +, Jason Morgan said: >The files in question were returned to Protel under NDA, they confirmed the >problems as reported and indicated that at present there was no fix. > >Sorry, but I can't transmit designs to the public, at least without NDA, >thanks for the offer anyway. What I have done with this sort of confidential data (even when sending the file to Protel) is to do a global search and destroy on all PCB parts and change their values to 10k (You see a "10k" 256-ball BGA does not contain a lot if IP). I then clear the netlist. If the board is incomplete, and the netlist from the sch is required, then it is a little more complex, but still do-able. I create some dummy schematics and PCB by copying the correct ones, immediately synchronise to make the following processes simpler. I then, globally remove every netlabel of all sheets, rename all the power supplies to meaningless names and change all the component designators to R? or A? or something meaningless. Re-annotate. Then change all the part types to 10k or some other silly value (including all ICs, caps, R's, connectors etc) and synch to the PCB. The resulting netlist and refdesignators convey almost no useful info - just point-to-point connectivity. All identifying text on the PCB is then removed, and all mech layers removed - apart from maybe the outline and the keepout. I then try to remove as many rules and classes as possible to reduce the chance of there being some useful IP embodied in these. However, it is likely that mucking about with the rules is very likely to change the suspect behavior, so this has to be done with some care. I may also rejig the mech outline to mask the target application a little. Possibly remove a few mech holes as well. Then confirm the problem still exists. I then only send it to people who I think I can trust. Not to the public in general. So Jason, if you would like others to try to see if you have hit a limit on the capacity of Protel, this may be one option. I would also be prepared to look at it. So I think you have three long-term members of this forum (at least) who are prepared to see what your file does to their machine. I would be very interested in the results of such a test. (I run Win2K, SP2, 256MB, PIII-450). I for one do not discount the troubles that Jason has reported over some time on this forum. However as others have said, quite a few of us see very very few Protel crashes these days, and there must be significant differences in the hardware we run.

I've been known to use the autorouter where it would save the client money. Not for every job, definitely, but it remains a valuable tool. Obviously, it can stand to be improved, many of its shortcomings are irritating because they should be so simple to fix, like the little tracks that meander all over the place before settling down to connect. I mean with no obstructing primitives! -- so cleanup should fix these.

I do not advise ignoring any DRC errors or warnings except the one about primitives on inner planes because there is no workaround that is practical, as far as I know. (It is good practice to place primitives to clear the edges of inner planes. This could conceivably be done Leaving false errors greatly improves the chance of overlooking real ones. Further, every time one works on the design, one will have to make a decision to ignore that error. Not good. There are better ways. In the matter at hand, one was given. As to "scratchable connections," virtual shorts may be used (this is a pair of primitives that are short of contacting each other by a couple of micro-inches. The gap will not survive photoplotting, film, or fabrication (unless some intrepid soul edits the gerber). Another method is to assign a mech layer to such shorts; this mech layer is then merged through special gerber setups in the CAM Manager. Both of these are set-and-forget. (the virtual short involves a special design rule that allows those two primitives to be extremely close to each other.) both of these methods leave DRC in place to check that each branch of the shorted nets are properly routed and distinct.

Sure, the memory bus is pretty well characterized, but all memory chips come off a line where they are tested, and some percentage of them have bad rows and columns. The memory testing is not really rigorous, although most makers retest the 'stick' after placing the cips on it. I had an old 486 PC that ran Windows 3.1 and other software 'flawlessly', but croaked fairly often with the old DOS Tango PCB program. I accused Accel of faulty software. I retired that machine years ago, but pulled it off the scrap heap for some experiments with Linux. Linux found the hardware totally unacceptable, although another identical machine ran fine. It turns out it had bad memory - I think it was the cache memory, not the main DRAM memory, but I'm not completely sure on that. So, at least in that case, it was bad memory that only affected one program, seemingly. That WAS, of course, the heaviest program on that system. > Before I get flamed, I know there are some 400 FSB boards out there with 600 > or even 800MHz memory (no idea how it works though), but we aint got one - > have you seen the memory prices for it They do it by transferring data on both the rising and falling edges of the clock.

If an hour goes by that I don't use it, I am just looking at a design, not editing it. You DO have to understand the full implications of it, and therefore you have to understand the database behind the things on the screen. By that, I mean you have to understand what comes from the library, and what comes from the instantiation of that library component on the screen. In Schematic, most of a displayed component other than part number for (multipart components), symbol (DeMorgan, IEEE, etc), orientation, hidden pins and designator come from the library, and you need to edit in the library editor to change it. (If you can't select it separate from the whole component, you can't change it seems to be the rule. In PCB, you have much more flexibility, as you can change an individual pad, hole or whatever on a component. You can't MOVE a pad or hole with reference to the part, however. But, global edit is REALLY powerful, and can save an enormous amount of time when you learn to use it well. I admit, I had to make a few mistakes when I learned it the first time, and fouled up a board or schematic by changing more than I wanted to. I still have to carefully think about which match parameters I want set to 'same' and which to 'any' to have the right scope of action. But, I can't imagine Protel without global change!

Re: [PEDA] Protel usage
The ones I see used, and I use, are: - Schematic yes - PCB yes - Powerprint yes - CAM Manager yes - Simulator yes - quite often. I forced myself to work out how to use it fully. It took some time, and it is very fiddly to add new models. - Autorouter yes - 3D Viewer tried it for a marketing picture and it was close but no bananas - PLD yes - for 16V8, 22V10 and similar only - usually these are for little test jigs etc. Basically this is just CUPL. - Arrange Components occasionally on initial import - Autoplacer no - PCB Miter occasionally - Signal Integrity tried briefly - will use as necessary - Database Link no And some ones not yet discussed: - Spread yes - Chart no - Cross Selector yes - Synchroniser (EDS) Yes Yes Yes - File Find dunno - maybe I have - Help Advisor(the little '?' mark at the bottom right) Yes occasionally - HSEditYes - LayerStackupAnalyser Yes - LoadPCADPCB No - LoadPCADSCH No - MacMaker Yes - Macro Yes - MakeLib Yes - PCB_SSYes - SCH_SSYes - SchDWGUtility No - ServMake Yes (but the wizards does not work for me) - TextEdit Yes I have left off some that are pretty much parts of the main Sch and PCB packages. I am a many hats type - not simply PCB or PCB/Sch. This, no doubt, affects my usage. Of the servers that are currently available that I see no need for, and should *not* be part of the package, there is only one,: AutoRFQ - waste of time Those that need lots of work: 3DViewer - but with user controlled models this will have occasional application. BTW the SDK does have a height parameter for components. I tried writing a server to set this parameter but either I did not debug it fully or the parameter does not (yet) get looked at by the 3DViewer. Database Link - speed and formats Autorouter Autoplacer The major servers requiring a bit more work to dramatically improve integration: Sim - including models and the rather clunky method of viewing traces - but getting there and already very useful. Lack of some of PSPICE extensions is a bit of a pain. Sch - I want a more detailed ERC/rules based system for specifying layouts in the Sch. Closer integration with PCB. PCB - lots of stuff that can be made better as this is the core of the program that should be under continual improvement. TextEdit - Not too bad but not as good as a specialist editor like TextEdit (unfortunately the same name as the Protel server). Some irritating display artefacts. Consider the comments below. Spread - needs more work. Stability is poor and the Excel4 features are a little dated. Consider the comments below. Most of the other servers can do with updates to imrpove the full suite. On the text editor and Spread - I think I would like the option of substituting external programs for these. The external programs could be specified as being OLE Compliant, if Protel so desires, but why chase your tail on non-core stuff. We could then use 1-2-3, Excel or whatever for spreadsheets and TextEdit for text editing - in a seemless manner if the OLE integration was done well.

Each L >shaped "pad" on the footprint consists of a pad and a copper fill attached >to it because I want the solder mask on the fill. > >Anyways, when I run DRC I get a short circuit error between the fill of the >"pad" and the pad of the "pad". Is there any way to resolve this? This is standard Protel question #1. In Protel 99SE, you can have multiple pads in a footprint with the same name, and they will be assigned the same net, *if* you are using the synchronizer. The netlist load process has a bug that can cause problems. (It was not designed to be used with multiple identical pads; Protel tried to fix it so that it would, but did not quite get it right, the next load will *unload* the nets from all the pads. But the synchronizer works fine.) So you can use an additional pad instead of the fill. That pad can be tented so that no mask is applied. The other method of dealing with this is to assign the appropriate net to the fill. You can do this by unlocking primitives on the component, then double-click on the fill to edit it, then, presumably, relock the primitives on the component. Or you can run Design/NetlistManager/Menu/Update Free Primitives from Component Pads. In spite of the name, it will also update component non-pad primitives. I just discovered another option. I used Tools/Convert/Add Selected Primitives to add a fill to a footprint. I unlocked the primitives and moved the fill into contact with a pad. It automatically took on the pad net. (To use the Add command, select the primitives to be added, run the command, then click on the component and answer the confirmation dialog. This is a new command with Protel 99 if I recall correctly.) But if the fill is part of the footprint already, and especially if there exist more than one of these footprints, running Update is the best procedure.

Re: [PEDA] Protel usage
> Regarding the questions about 3D and autorouter, what parts of Protel do > you actually use? I have made my own comments to Mr. Rupinski's disection. Hope you don't mind my plagerism. - SchematicYES My only concern is that I wish the ERC checking was a little more comprehensive. - Global Editing YES This works just fine. Once you learn the nuances, its effective and easy. - Report>BOMYESThis should allow complete user control (Absolutely!!) - PCBYESCompared to others I've used in the past 15 years, it's intuitive and easy to use. - PowerprintYes, at first I hated it, now I love this way to print, makes making single PDF files from pcb layers so much easier. - CAM ManagerYES - SimulatorYESOnly used once, wish this was covered better by the documentation. - AutoRouterNEVER, and have serious concerns about layout people who do. (Unless using Spectra) - 3D ViewerYESCompletely useless! As I have said previously, Protel should buy the export applications from Desktop-EDA. 3D export to IDF/STEP/IGES or Solidworks is a necessity for real and efficient product integration. I can't even begin to tell you how this has improved the relationship between PCB and Mechanical design. - PLDI would if I had the time to learn this part. - Arrange ComponentsNo, - AutoPlacerNo, - PCB MiterNo - Signal IntegrityUsed once, will definitely keep trying it. - Database LinkYES, but this used to work in Client 3.x, it has since been totally screwed up!! Takes way to long to be useful, and our company NEEDs it to work properly. ARE YOU LISTENING PROTEL! - LibraryNo, Protel libraries have never been reliable or adequate. I lost all confidence when the QFP-100 only had 80 pins. - Send By MailNever tried. - CamtasticYESI have used it to convert old gerbers into something Protel can load. - Intuitive InterfaceIf you have ever used PADS, you'll think Protel is one the MOST intuitive programs out there. I have never seen a more User hostile interface than PADS. - SDK EDA server - YES, but not myself. I have had some servers built for me by others, again not covered particularly well but the documentation. - ProductivityThis is a function of the User, I have used Protel since the DOS Autotrax days and have seen the rise and fall of productivity. The worst version of Protel ever produced in my opinion was Protel 98, and a tie for the best is Protel for Windows 2.8 PCB and DE99SE given that you have to judge each one at it's time of deployment. Obviously 99SE is more powerful, but can you imagine trying to run it on a 1991 top-of-the-line PC. I think not. No software is perfect or free from bugs, just look at Windoze, however you can either work around it and make the best of it or sit there and complain. Yes I would like some things fixed, but considering what else is out there, I am making the best of the current situation.

Re: [PEDA] Copper Calculations
Re: [PEDA] Protel's Good/Bad points (WAS:Using 3D)
Believe it or not I have seen a hardware memory problem crash Protel. It was the only thing that needed enough memory to actually cause that SIMM to be used. Of course this a few years ago running something like Windows 95 on a pentium 133, but the point is that it can happen since most low to mid level PCs do not have ECC, and windows starts allocating from one end of memory. Of course while I won't rule it out without more evidence I think it unlikely that his printing problem is RAM, but rather a combination of DLL hell and poor error recovery.

New PCs are on the absolute bleeding edge, which means some blood (and sweat and tears) is bound to be spilt somewhere. If Protel is the largest app (with your design file loaded) you run on that PC, it could be using an area of RAM that is not fit for use. Instead of running the latest 2 GHz P++, maybe you should try it on an older, slower PC. The most advanced PC I have right now is a W2K/SP2 dual-PIII 1.0 GHz with 512MB PC133 and a Matrox G450 video card. Rock stable - but then I haven't done any Protel jobs as huge as the one you are doing. Protel 99SE has plenty of bugs and quirks. But no program, no matter how good, can overcome a marginal, overclocked, metastable, negative-timing-margin PC.

A couple well-known, but not well documented things. The most important is to have a keepout border around all the components that is made up entirely of lines. No arcs, and no fills. The software needs this to set up a boundary to its search space. (You can have fills in the interior of the keepout, but the border should not contain any.) I think arcs anywhere on the keepout may cause problems. You need to assign nets to all split planes, and make sure the split plane interior regions don't overlap. (The lines which delimit the split plane regions can overlap.)

Every attempt I made to take a standard file format and get it to produce a Xilinx-usable bit stream for FPGAs or configuration map for CPLDs ended in failure. I sent the offending files and error message information to Protel and never heard a word back. They obviously had no interest in making PLD work for Xilinx. I also tried to get .xnf and .edif files to go into Xilinx's place&route software, but they didn't like the file's format. The Xilinx tools from back then were abominable. They have improved it considerably since then, but I still prefer the Protel environment by a good margin.

(1) They have said that before when there was an easy fix. Not always, of course, but it is highly unlikely that there is no workaround for a problem. Maybe I have seen that once. (2) Obviously we do not expect proprietary data to be transmitted "to the public." In fact, we don't want attached files to go to the list. Speaking for myself, I'll sign an NDA; but it should really not be necessary. A printed circuit design with no comment fields, even if everything else is there, is completely inadequate to reproduce a design. Further, it is likely that some of the rest of the data could be eliminated and still the file would display the problem. But just the comments and a PCB file with no schematic is little more than a pile of primitives, I cannot conceive of how it would be used except possibly by someone who already had a lot of inside information. >I can say that there are about:- >1100 components spread across two sides >1000 nets >1 track segments (last time I talked to the guy doing the layout) >2450 vias >450 holes >6 layers >Several silk and mech keepout layers etc. >5000 SMT pads >15 Polys on two layers That's a large number of components, but not terribly unusual. The rest is not even truly large. The Board Information Report includes polygon fill track in its report so perhaps those polygons were not filled for the report. I just looked at a moderately large design that I did a year ago, it had 568 components 961 nets 91,168 tracks 2398 vias 9431 pads (mostly SMT) 10 polygons. The track count includes the pour track. This design had no problems. >.DDB runs at about 20-70Mb and lives on the same HDD as the program. That is a huge ddb. If it has not been done, I suggest emptying the recycle bin and compacting the file. The file I described had a 6.1 MB ddb file. I have automatic compact on exit set. If I were getting crashes all the time, I might be nervous about that. >All in a 10" x 8" board area > >In any case, Protel works on at least one machine here (if with some >deficiencies) without crashing (too often).

Now, to real life. A program like Protel is *inordinately* complex, and the market is relatively small and market pressure high, so beta testing is limited in what will practically be tested. We are still discovering, occasionally, bugs that apparently escaped the notice of all of us for two years. Obviously, these bugs do not affect routine operations, or they would have been much more easily identified. Sure, every bit of data should be checked for integrity, but there is also another constraint: many Protel operations must be completed quickly. As I am sure is obvious, complex checking can greatly lengthen the time it takes to process data. If you have to draw 100,000 tracks, how much checking are you going to do? Or are you going to trust that what was written with error checking remains good? >So far as the poly problem goes, the fix in that case it to set 'Auto >Repour' to 'Never' and then use my 'Repour All Poly' server, available on >the yahoo group, failing to do this results in some long waits!! And there are other workarounds. The problem here is truly one of a massive amount of data. Perhaps Protel could be much more efficient in processing the data, perhaps not, I really don't know. I do know that it is much faster than other CAD programs I have used, perhaps it is slower than others >Explain why a fresh re-install of 2000 + sp2, then Protel +sp6 crashes on >several operations, even on first run. I'd ask "what operations and using what data?" But given that this is *not* general experience, there remain not too many possibilities. First of all, uninstall and reinstall does not remove all initialization files, and these files can sometimes cause crashes. It is necessary to remove those files.

The response I got was that the software is tested on a variety of different platforms in order to maximize compatibility with the greatest number of platforms possible. But the idea of controls is valid. My personal choice is a (publicized) formal certification procedure which Protel would follow.

My piers are using the same configuration with different results. Their machines crash often. Differences in my machine and theirs: I disable all power saving schemes, theirs is running Screensavers disabled, theirs is running McAfee completely disabled and removed on mine, theirs is installed and running Norton disabled and removed on mine Norton is running on (some) of theirs Mijeniz FIX IT UTILITIES installed on mine but not running in the background. I run the FIX IT Wizard and clean and repair the registry EVERY week. I also will run it anytime after I run a piece of crap called AutoCad. Autocad can cause Protel to hang up, so I try never to use it on the same machine. Also drivers for my external zip drive have been known to cause my system to hang up, but that is not a Protel problem. Any other crashes I have had in the past year, which I can relate to protel occurred after I was handed a file from another designer. One file had a via outside of the work area which caused both Protel and Spectra to crash. The only other software I run on my PROTEL machines are: Windows explorer, Outlook, Lotus approach, Camtastic, Wordpad,winzip, that's it. All other software gets installed on one of my "other" machines so that I don't contaminate my working and delicate configuration. Remember this is my workstation that I rely on feeding my family with, so I don't take the risk of just adding any software to this machine. I run ACAD, PADS, Spectra, Orcad, accounting software and anything else I buy on a other machines. Hope this gives you an idea of type of configuration I use.

Re: [PEDA] Protel's Good/Bad points (WAS:Using 3D)
most of this memory stuff also has ECC (error correction code) of some sort that should be fault tolerant on the board/chip/asic level (not the software/application level)... I don't know much more about it, but if in the software, you assign a memory pointer incorrectly and then try to use it, you would very likely crash on the software/os level I doubt it is the memory...

Re: [PEDA] Protel's Good/Bad points (WAS:Using 3D)
Nice idea, but I don't think errant dram bits hunt and seek just Protel, if the dram were faulty, I'd expect 2K (or any component of it) to dump at least some of the time, also the bist would be likely to fail... The majority of PC's though running at GHz frequencies still use either a 200 or 266MHz local bus and a 100/133Mhz memory bus, and thats tried and tested. Before I get flamed, I know there are some 400 FSB boards out there with 600 or even 800MHz memory (no idea how it works though), but we aint got one - have you seen the memory prices for it J. -Original Message- From: Bagotronix Tech Support [mailto:[EMAIL PROTECTED]] Sent: 19 November 2001 16:41 To: Protel EDA Forum Subject: Re: [PEDA] Protel's Good/Bad points (WAS:Using 3D) > Explain why a fresh re-install of 2000 + sp2, then Protel +sp6 crashes on > several operations, even on first run. > > Explain why printing on one machine with exactly the same graphics card, > graphics drivers, print drivers etc. works fine.

Re: [PEDA] Protel usage

This is a constructive and informative thread. I've added some comments and I'm forwarding a copy to Altium. Other responders may also consider sending their comments to Altium. I wish I had time to be more thorough. - SchematicYESSome editing refinements would help. Cutting out wire sections to insert components saves work and reduces errors over deleting the whole wire and rewiring. Clicking on unused area to deselect all (maybe right mouse) would reduce unintended operations. - Global EditingYESThis feature doesn't do what I expect. It is too involved and confusing for rapid, productive editing. In some cases it is necessary to revise a library component to edit a repeated schematic or sheet component. - Report>BOMYESThis should allow complete user control over format. It is irritating to some of my clients not having ITEM NUMBER in the leftmost column. - PCBYESSee other PEDA threads for a wealth of user comments on PCB issues. - PowerprintNOPlain old print only. Never generated a PPC file. - CAM ManagerYES - SimulatorYESNeeds some improvement. Node numbers, titles and captions for response plots, separate power and signal connector menus, clearer error messages. - AutoRouterYESA simple but dense crosspatch pattern worked under SE 99 SP5, but would not complete under SP6. Altium's response: "We improved performance in other areas." I did not appreciate that. See other PEDA threads for a wealth of user comments on AutoRouting. - 3D ViewerYESVirtually useless. Protel needs a 3D component editor. A 3D form factor checker would also be useful. Eliminate bugs. - PLDNO - Arrange ComponentsYESI am not yet proficient using Component Classes and Rooms. I wonder if schematic based attributes (eg, pre-assigning selected components to pre-defined Rooms plus adapting the hierarchical capabilities to define a floor plan) could make the AutoPlacer work better. - AutoPlacerYESNeither Cluster nor Global ever provides what I intend. Usually lots of manual re-positioning. A third option is needed: SCHEMATIC BASED MAPPING. Experienced, competent engineers and designers often draw their schematics according to function and signal flow. They then arrange their PCBs to follow the same flow. Doing this 'automatically' is easier and faster than using Rooms. It is simple to have the AutoPlacer arrange the hierarchical blocks and the components in the same relative position as on the schematic sheets. A tiling algorithm could be used to save real estate. Only a little pushing and shoving would be needed. - PCB MiterYESOccasionally during final adjustments. - Signal IntegrityNOT YETBut I see potential value in it. - Database LinkNO > What else do we have? - LibraryThis is haphazard and difficult to organize; a methodical housekeeping procedure is sorely needed. Technique for adding vendor and user components is esoteric and clumsy. Simulation MODELS in 'Misc SPICE/PSPICE part LIB' don't work, nor is there any clue how to make them work. Except for not disclosing the installation procedure prior to the actual task, the recent library additions are very useful. But I've seen no new activity in about eight months. (The TMS320VC5402 is a hot part and I could use a symbol and footprint today.) - Send By MailDoesn't work. Crashes my system and looses files. - CamtasticYESFor final checks in my case. - Intuitive InterfaceThis is debatable. Protel 99SE is one of a suite of tools I use, and about 3/4 of them are easier for me to use than Protel. Since I can't hone my Protel skills every day, this is an important issue for me. - ProductivityThe promise is there..but it has yet to be fulfilled. The two biggest problems are bugs and a comprehensive users' manual. The technical support response is only about 40% effective in terms of problem resolution and closure.

Michael did note that, in his experience, many designers who have problems with Protel don't know how to use it, apparently Mr. Morgan took this personally. My comment on this is that all of us have ways in which we can learn more about how to effectively use the program. Sometimes we have tolerated irritations for years without realizing that there was a simple way around them. This can include crashes. When I was first running Protel, I had crashes all the time. They are now quite rare. What is different? Well, service packs, a Matrox Millenium G200 card with acceleration turned off, and I run a resource meter and don't allow Windows 98 to run out of resources, probably the number one cause of crashes on W98 systems. That's a W98 problem, really, but Protel particularly exercises the operating system. This, however, should not be a problem with Mr. Morgan's Windows 2000 machine, which does not have the severe resource limitations of Windows 98. >The only reason we are using it at all, and not the latest Orcad (which we >also have and use) is down to my experience with Protel. > >Protel crashes, its protel's fault (even you admit that). I see a Protel crash once every few months. There seems to be some problem with the spreadsheet server or its interrelation with the other tools. Aside from that, crashes are very rare. Of course, Mr. Morgan may be exercising parts of the program that I'm not. > As for not using >the bits that crash, I find the inability to print, save or load a file a >bit of an inconvenience. To be sure. But that is not the experience of the vast majority of us. There are a number of possibilities: (1) something is trashed in Mr. Morgan's Protel installation, (2) something is awry with his system, or with the interaction of Protel and his system, or (3) he is using the program in a non-standard way, which will cause defects in the less-tested aspects of the system to be exposed. The fourth possibility, that Protel is intrinsically buggy, we can rule out because it is working so well for most of us. > And as for missing and misplaced entities on >plots, well >that's to be expected these days nothings perfect. It is not to be expected. Missing entities on *photoplots* should be *very* rare. Each one of these items deserves to be studied in detail. If a file consistently produces an error, it is extremely valuable information for Protel, and there are those of us on the user group who are ready and willing to receive files and test them on our systems to confirm a bug or to lead us to suspect that it is a system-related problem. >Ok, yes I admit its got much better (so far as features go) since P98, but >at the expense of repeatable stability.

EDA UK confirmed both these bugs and passed our design to >Protel for investigation. Which could mean that it went into a black hole. Obviously, we can hope otherwise, but the reality is that Protel has a limited staff and when a problem appears that is difficult to reproduce, it may get set aside in favor of more satisfying problems. One may say that this should not happen, but as long as we have human beings in charge, it will happen from time to time. For this reason, I do recommend communicating regarding suspected bugs with the user group. If others confirm it, then we know we have a bug and we can bring it to Protel's notice with our collective weight. If we cannot confirm it, then we may put more effort into identifying system problems. Often one of us will take a file that produces a crash and reduce it in size by cutting out primitives, each time saving it and testing it for continued manifestation of the problem. Sometimes this process, just by itself, identifies the problem. A bad file can feed Protel data that is outside the expectations of the programmers, and it is impossible to test all the possible configurations of data that can take place in the real world. >It seems that the crashing is usually down to known problems when you have a >very large design >1000 components, many polys (these are the killer) and >many tracks on a mixed through hole / smt design.

> So we've got the same files on the same everything, what's left? Protel is > sensitive to PC hardware, surely not.. It's possible even though it gets less likely with newer versions of Windows. On the other hand Protel and most windows programs are sensitive to DLLs. Protel is more sensitive to DLL Hell than some programs. And Yes I agree that a well written and QA'd program does not have the poor error recovery that Protel can experience, but I would rather have poor error recovery than logic errors that lead to things like gerber files being 1% small.

It seems they have poor (or no) error recovery from an open printer call to a non-existant printer driver. This is especially in the PCB print preview. The revocery method that seems to work best was to remove all printers from thesystem then add the printers back. Most of the bugs I have found in Protel have been lack of good error recovery more than logic errors, although if I want to get picky I could go into all the dialog boxes with useless tab orders.

Re: [PEDA] Protel usage
I'm curious. How many upgraded to Protel 99 SE and thus do not have the "Protel 99 SE Designer's Handbook", and how many people do have it? How many of the people with the Designer's Handbook feel the simulator, signal integrity and PLD are poorly documented? The reason I ask is that at the last job we upgraded to 99Se and the help files sucked for figuring out how to use the new features, but at this job we bought Protel new and the Designer's Manual is actually quite a bit of help. I just wish they had put the Designer's Handbook into the help files, so I don't have to go get the manual back from the other engineer everytime I can't remember something.

Re: [PEDA] Protel's Good/Bad points (WAS:Using 3D)
The files in question were returned to Protel under NDA, they confirmed the problems as reported and indicated that at present there was no fix. Sorry, but I can't transmit designs to the public, at least without NDA, thanks for the offer anyway. I can say that there are about:- 1100 components spread across two sides 1000 nets 1 track segments (last time I talked to the guy doing the layout) 2450 vias 450 holes 6 layers Several silk and mech keepout layers etc. 5000 SMT pads 15 Polys on two layers .DDB runs at about 20-70Mb and lives on the same HDD as the program. All in a 10" x 8" board area In any case, Protel works on at least one machine here (if with some deficiencies) without crashing (too often). That eliminates user error and bad files (incidentally neither of which should EVER affect a well written program, I know, as well a hardware engineer I'm also a programmer). So far as the poly problem goes, the fix in that case it to set 'Auto Repour' to 'Never' and then use my 'Repour All Poly' server, available on the yahoo group, failing to do this results in some long waits!! Explain why a fresh re-install of 2000 + sp2, then Protel +sp6 crashes on several operations, even on first run. Explain why printing on one machine with exactly the same graphics card, graphics drivers, print drivers etc. works fine. On the new one it does not, if it prints at all, many entities are missing, especially outline boxes. (Note I've seen the latter on several past Protel installs with certain graphics cards, notably ATI) So we've got the same files on the same everything, what's left? Protel is sensitive to PC hardware, surely not.. J.

Re: [PEDA] Antwort: Antwort: Autorouter
> same here. Even medium designs won't route and end up with an "unable to > initialise". Does anyone know a reason and workaround for this effect? I have found this to usually be due to components outside the keepout area or the keepout area being incomplete or inside out. The other thing that will cause this is certain DRC errors, but I can't remember which exactly. So check your keepout and components then run a DRC. Yes it would be better if it would give you a good error message like "unable to initalize due to component outside keepout", but I think this is more a specification error than a real software bug.

Re: [PEDA] Protel's Good/Bad points (WAS:Using 3D)
Jason, I figured you might be offended, I will be glad to look at or help you in any way I can by examining your file. Seriously, I am not trying to defend Protel, some of you will recall I was one of the first to use some very harsh language when 99 was released with lots of bugs. I even returned it to Protel and they gave me a full refund! 99SE with SP6 is a solid (very rarely crashes) program loaded with features found in more expensive programs. (Again, I speak for the PCB package only) Polygon pours should take seconds at most. You have to be doing something wrong, please take no offense. I will extend my olive branch and ask you to send me any file so I can take a look at off the forum. I will be glad to offer you my assistance, as I look for the challenge.

Re: [PEDA] Protel's Good/Bad points (WAS:Using 3D)
Michael, First lets get something straight, I take offence at your questioning my competence with Protel, I've been using it for a very long time and am familiar with all of its usual weird behaviours (even though they are still unacceptable) The only reason we are using it at all, and not the latest Orcad (which we also have and use) is down to my experience with Protel. Protel crashes, its protel's fault (even you admit that). As for not using the bits that crash, I find the inability to print, save or load a file a bit of an inconvenience. And as for missing and misplaced entities on plots, well that's to be expected these days nothings perfect. Ok, yes I admit its got much better (so far as features go) since P98, but at the expense of repeatable stability. -(A bit of background - you don't need to read this bit) Our first dedicated cad machine was a 1GHz P4 with 1G RAM, it *ONLY* runs Protel and win2K. We bought this as protel was pausing for more than 30 seconds per pin as a result of an edit of through hole components, it was also crashing many times a day. EDA UK confirmed both these bugs and passed our design to Protel for investigation. It seems that the crashing is usually down to known problems when you have a very large design >1000 components, many polys (these are the killer) and many tracks on a mixed through hole / smt design. The other problem is down to a bug with the on-line poly repour it seems to take ages when you have a large number of polys. All we do know is that an 1 hours lost work of one of our engineers costs more than an extra gig of ram. A newer machine was bought for a 2nd engineer. This is a dual processor 1.7GHz P4 with 1.5G RAM (at the time the fastest we could sensibly afford) Initially on the new machine all printing activity from within Protel would cause a crash, from experience we know that protel is very sensitive to graphics cards (surely not the fault of protel), so changing it sorted some of the crashes (its now the same as the first machine) Protel still crashes, so what's going on? Probably a fault of the IT guy who (despite my advice) wants lots of patches installed under windows, even if there is no visible problem, anyway that's his problem. So where am I going? Ah yes, Michael, as you machine seems to be so stable, perhaps you could tell everyone its build as its seems you've got it right.

Re: [PEDA] dual-sided connector footprint ??
thanks to all who posted on this. when i had tried this before, i had set up multiple pads on the top and then tried to group move them to the bottom. i'm sure there is a way to do this, but with a minimum of messing with it, i couldn't get it to work. HOWEVER, i found that individually i could easily move each pad to the bottom and i believe i've got my connector footprint made. thanks again, miker -Original Message- From: Jon Elson [mailto:[EMAIL PROTECTED]] Sent: Friday, November 16, 2001 4:50 PM To: Protel EDA Forum Subject: Re: [PEDA] dual-sided connector footprint ??

I'd look in the library for card edge connectors. These have essentially the same sort of pad layout as you are talking about. See how those are done. The one problem is that these don't really have a physical presence on the board, but the pads are there. Side of the board doesn't make as much sense as for a physical component, bu it will swap the even and odd pads if you flip the part.

Re: [PEDA] Antwort: Antwort: Autorouter
Steve, same here. Even medium designs won't route and end up with an "unable to initialise". Does anyone know a reason and workaround for this effect? Regards, Gisbert Auge N.A.T.

Same here. I've got Specctra, so I don't care so much about the ARs inability, but I've just convinced a customer of mine to buy Protel so they can do their own maintenance of the board I've just done for them - it doesn't require Specctra, but to hand-route it would be very very dull. I suspect I'll need to know answers pretty soon. (My experiences with the autorouter normally end up with an "unable to initialise", or a design where the router seems to paint itself into a complete no-hope situation, and gives up / stops trying. All very depressing). Specctra, of course, may not be available as a standalone product - I have little love for Cadence.
