gEDA-user: Panelizing methods?
Heya List :) Any suggestion on the best way of makeing seperations in a panel using only the drillholes available on the cheaper PCB services. I was thinking of placing a bunch of .090 holes .100 apart. Then it's a snap and file when the panel gets here. The panel is not uniform, there are 4 different boards on the same panel.

Some don't. I usually draw silkscreen lines 100-150mils from the edge of the board and use a bandsaw or a hacksaw.

gEDA-user: SPICE gaf
Stuart's tutorials on using SPICE with gaf are well written and easy to follow. Unfortunately, they need to be updated. Specifically, loading the schematics in gEDA/examples/RF_Amp (which are packaged in the 20061020 gaf release), give warnings like: Loading schematic [/home/scott/projects/platypus/spice/ex_RF/MSA-2643.sch] WARNING: Symbol version mismatch on refdes C1 (capacitor-1.sym): Symbol in library is newer than instantiated symbol Minor version change (file 0.100, instantiated 0.000) Similar warnings also exist when the schematic is netlisted: $ gnetlist -g spice-sdb -o MSA-2643.cir MSA-2643.sch However the netlist encounters an error too (and is probably related to the warning): Found a pin [X2] on component [2] which does not have a label! Using SPICE backend by SDB -- Version of 12.27.2005 schematic-type = .SUBCKT Q1_MSA26F ERROR: In procedure : ERROR: Wrong type argument in position 1: #f Finally, the SPICE circuit files that are extracted from the RF example (and also package in the 20061020 release) fail to run under ngspice revision 17 (this version of ngspice is installed by yum -- I don't know if this binary had the XSpice option turned on or not). Note, there's a hard coded include directive in these examples that one must adjust. First there's this warning (it appears twice): Warning -- Level not specified on line (bf=1e6 ikf=5.895e-1 ise=2.838e-19 ne=1.006 vaf=44 nf=1 tf=5.37e-12 xtf=20 vtf=0.8 itf=8.872e-1 ptf=22 xtb=0.7 br=1 ikr=4.4e-2 nc=2 var=3.37 nr=1.005 tr=4e-9 eg=1.17 is=1.79e-17 xti=3 tnom=21 cjc=3.717e-14 vjc=0.6775 mjc=0.3319 xcjc=4.398e-1 fc=0.8 cje=3.217e-13 vje=0.9907 mje=0.5063 rb=2.325 irb=3.272e-4 rbm=2.5e-2 kf=1.026e-24) Using level 1. And finally, when you run the simulation, there's a convergence error. 1) Has anyone updated the example schematics? I just checked CVS and it appears these are 3 years old. 2) Has anyone successfully ran the example SPICE decks under ngspice-17? I might do (1) -- assuming I can get my setup working.

gEDA-user: PCB Silk Screen vs ViewMate
Well I just successfully tested and signed off on my first gEDA board. It was a small 5x3 4 layer PCB that I had FAB'd at PCBexpress.com. Quality wise this board is on par with my last board which was a fairly complex 16 layer PCB done with Mentor. Hopefully I will never be using those other programs again =) Anyways one thing somewhat bothers me and I am sure I just probably did something wrong. When I view the Silk screen in ViewMate, all the reference designators are a lot wider then they are when viewed in PCB. For example, a lower case e in PCB is perfect text, but in ViewMate there is no hole in the lower case e because the line width is a lot wider. Now this isn't that big of an issue because you can still make out everything on the board. But it just makes the silk screen look like it is out of focus. Oh, and the physical silk screen on the board looks exactly as it did in ViewMate which is what I expected... ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
Re: gEDA-user: PCB Silk Screen vs ViewMate
When I view the Silk screen in ViewMate, all the reference designators are a lot wider then they are when viewed in PCB. Known bug. You can minimize it by making sure the minimum silk screen is set properly in the board sizes dialog. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Re: gEDA-user: Re: I need to open and print a PCB created in ExpressPCB:What are my options?
I understand how you feel, but with these particular guys at least...they're very down-to-earth. Every one of them has shown a real willingness to help people, even newbies, whenever possible. Well that's good. I'll be sure to pay close attention to their suggestions. I've never been a fan of PC hardware (too slow cheap-feeling for my taste) so I don't mess with Linux very much. I'm limited to x86 hardware because its cheap, so it doesn't matter much to me if it feels cheap. As for Linux at 13, I can't say I was a very impressive user. My first memory of running Linux is actually of not running it. I got a kernel panic on the first try because I didn't know about boot loaders or about specifying a root= in grub. I know a bit more now, but I still can't write much more than a basic bash script of a few lines of assembly. And the PDP-11? Wow, I've only ever read about that thing. :-) But I've worked with people who would spend a whole day calculating what I can walk to a bench and measure in seconds. THAT is ridiculous. Yeah. My experience in lab has been that generally the measurements (if taken properly) are more than accurate enough for troubleshooting and adjustments. I'm clumsy though, so the calculations (at least the simple ones) are often faster for me. Breadboarding a full-wave bridge rectifier takes me 10 to 15 minutes, running the calculations can be done in under 2. :-/ One other thing to keep in mind. Hacking on embedded systems will teach you how to write efficient code, and you can take those skills right back to big machines at great benefit. In these days of Windows morons writing simple programs which require hundreds of megabytes of RAM...these guys are not programmers. In the world of embedded systems, in smaller applications one frequently finds oneself writing code to run on a system with a few dozen bytes (yes bytes) of RAM. And they do *real work*. That's for sure. Right now we are learning how to program basic stamp microcontrollers in class, and while I'm not fond of them (they use PBASIC: a proprietary programming language! Can you believe such a thing?) I can see how they require efficiency. I write an 820 byte program for one of these things that would follow a flow chart for troubleshooting diesel engines. It turned out that by shortening some output messages to the debug terminal and eliminating some stray CASE statements, the code could be squeezed into 70 bytes! The guy next to me actually didn't use the debug terminal (which requires a serial port connection to a PC) and managed to get his program into 20 bytes using dip switches for the simple yes/no questions! I am uncomfortable in hardware though, so I wasn't willing to use switches. :-( -- Windows [n.] A thirty-two bit extension and GUI shell to a sixteen bit patch to an eight bit operating system originally coded for a four bit microprocessor and sold by a two-bit company that can't stand one bit of competition.

gEDA-user: pcb - shell command
hello, i started using gEDA tools last week to design a small PIC board. it looks like a nice suite! finding out gschem uses guile, and PCB files are as good as compatible with scheme 'read' made me smile :) i was wondering though if it is possible to use PCB to directly invoke external shell comands, without using them to read or write stuff. basicly what i want is to invoke 'make' from PCB, and subsequentally reading in some files. i didn't find anything about this in my first read of the PCB doc. cheers tom ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Are you sure this is what you want? I.e. System(make,ls,echo) runs
three commands? The lesstif GUI allows spaces in its command window,
so :system ls -l tries to run ls then runs -l.
Maybe you should concatenate the arguments with spaces into a single
command line?
Also, you should check the exit code of the command, and fail the
action if the command fails.

gEDA-user: PCB: Polygon segfault
Hi,
While designing a board I got a segfault in PCB. I have a design with a polygon
connected to GND on the component layer and among others the QFN20_4_EP
footprint on it. This particular footprint has a very small clearance which I
noted only after I drew the polygon on top of it.
If I now press F2 and start to pan the board I get a segfault. I think the
polygon clipping code goes a bit wrong, I see also constant flashing in the
polygon area.
I attached a small patch which at least fixes the segfault for me for now. I
have a testfile which gives the segfault, but I don't want to send it to the
list. Attached is also the backtrace. If one of the developers needs the
testfile, please let me know, I can send it off-list.
I use the CVS version of PCB from early January.
Thanks,
Hans

Re: gEDA-user: PCB - grid dots not visible when board is flipped.
I think what happened is that when the lesstif version implemented the left-right flip (vs. up-down as it worked previously) there was something that didn't propagate back into the GTK code. It wasn't lesstif, it was that the concept of flipping moved from the core to the GUI. Both GUIs needed extra code to implement the mapping. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
gEDA-user: gEDA meeting in Sioux Falls SD
Where in the world is Sioux Falls? And did the subject specify the state of South Dakota??? Yep there's a few geeks in the Midwest, not just the east and west coast. :) Just in case there is anyone on on the mailing list that is in the Sioux Falls SD area. I would like to extend an invitation to this meeting who is entertaining the idea of doing a PCB design with gEDA. We are meeting at Colorado Technical University on Feb. 15. By the way there's pizza and soda involved. A couple of months ago I chose gEDA as the tool suite for laying out my first PCB. With a little help from people on this message board and a couple months of free time I was successful! I don't claim to be an expert at PCB design or even gEDA. But I do understand the basic design flow and can assist someone who needs a little assistance getting started. For many people the installation and use of Linux is just a little more than you care to bight off at one time, so I plan to provide a VMPlayer image at the meeting. Again I'm no electrical engineer since my background is Software Engineering so don't drive 2hrs to get that burning question about transistor saturation answered. There may be someone at the meeting that can answer it but it won't be me. If your interested and live nearby I would love to meet someone else who has worked with these tools. Get the details at: http://www.siouxland.org/ I apologize if this is a misuse of this message board.
