Re: gEDA-user: Working on a tiny schematics editor
Go for it! I think your idea is really neat. I'm a hard core Ruby programmer and have had similar experiences - you can say a lot in a little bit of space, the code is very readable, and coding goes quickly. I can think of some other useful applications for a Ruby version of gschem. A small, highly portable version of gschem that works without the user having to deal with Makefiles and such (if you've got Ruby and the needed gems, it just works). And the second idea: Ruby/Rails is a popular framework for building websites. It might be possible to use your gschem core and a different front end (javascript) to make a web version of gschem (so anyone could run it from any web enabled device) - I have a need for something like this today.

You may say: You should better use QT, C++, Java, Python, OpenGL... Maybe... So why I started that task, and why do I write this text? Some weeks ago there was a discussion about subnet support for gschem. The conclusion was, that I have to learn some guile to implement it. OK, some day I may do that, but currently my motivation is not really great. On the other hand, I am currently learning Ruby and GTK/Cairo, and I do not really love programming in C. So I started a Ruby parser for gschem schematic files, just for fun, and progress was really fast. Current state, after only 150 hours of work, is that I can read in most basic shapes and write a cairo PNG file. (OK, currently only embedded symbols work...) So chances are not too bade that I will continue working on it in the next months -- it is really easy and fun. A basic GUI and export of PCB netlist should be not too difficult. I am not sure if I will ever support hierachical design and other netlist formats -- that may be really complicated?

Re: gEDA-user: FT232R
My guess is that there is something different about the designs/applications which are experiencing the lockups/malfunctions - too many products use the FTDI USB to UART parts successfully.

Re: gEDA-user: terminators
I built a very similar circuit using an Altera FPGA and a 100MHz SDRAM with good results. To keep things easy, I did a couple of things. One, I kept the signals to the SDRAM as short as possible (around an inch long, in most cases). Second, I made sure that the clock that the SDRAM controller sees and the clock of the SDRAM have minimal skew. I did this by running the original clock into the FPGA and then running it out 2 pins. One went to the SDRAMs and the other went back into the FPGA, but the etch length was the same as the length that went to the SDRAMs. Then, I used a PLL in the FPGA to look at the arriving clock and skew it (which are really the output clocks) to match the clock of the SDRAM controller. That way, I could be sure that the clock that the SDRAM sees and the clock of the controller were the same. Without that, it's very hard to meet all the max/min setup and hold times of the SDRAM and SDRAM contoller. Steve DJ Delorie wrote: That's what I'd do. At the sort of volumes you and I work with it's a lot cheaper to use a FPGA big enough to include chipscope/signaltap even in the full design than to allow for an LA hookup. I'm limited to QFP packages, though. I picked the 3A family for some reason, ah, power - the 3A doesn't need a 2.5v interface block. I haven't tried synthesizing into the 3A yet to see how much space I'm using. Why not just use chipscope? I thought you could get that for free these days (although admittedly I use Altera mainly for free Signaltap myself). Well, if chipscope is freely downloadable, I'm OK with that. Hard to believe the LA expects signals that fast without active probes. Well, I said Ms/s, not MHz. It's mostly useful for measuring skew and jitter relative to other pins. I usually run at one of the slower speeds, as the LA's compression doesn't work at the fastest speed. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Re: gEDA-user: OT: Recommendations for laptop?
I've also been using a MacBook (Pro). Very solid, easy to use GUI with lots of point and click support for different file formats (handy when viewing/porting graphics files), and it's *nix. People have ported lots of open source tools to the Mac (See Fink, MacPorts). I have 4GB of RAM and run Fusion (VMWare), so I can also run stock x86 Linuxes (for testing), and I even have an XP image for the occasional tool that has to run under Windows (still a few out there). I think owning both the HW and the OS gives Apple a more stable system than most others, since they only have to test for a few HW configurations (not for 1000s of PCs). I've had less trouble running VMWare Linux images on the Mac than I have running them on bare PC hardware - they just work. I tend to run MacOS all the time and run all my delopment tools and OSs on top of it. Stays up for weeks (usually power cycle only for updates). Base units aren't too expensive (probably some used ones out there for $500 - $750). The memory is easy and cheap to upgrade (uses standard DIMMs). The hard drive is also replaceable (I just put in a 500GB drive in mine - $115 from NewEgg). Hard drive replacement isn't as easy as the RAM, but it only takes an hour or two.

gEDA-user: pcblander Landpattern Generator Update
Since the initial release of pcblander, there's a new capability. In addition to flexible generation of footprints from source files, now pcblander can append the source code into the landpattern, so you never loose it and always know what the landpattern is. If want to know exactly what a landpattern is, all you have to do is browse the top of the landpattern file. The pcblander code is commented out from pcb, so the landpattern will load without a problem. If you edit the human readable top part of the file, the landpattern can rebuild itself if you type it at the command line. Here's an example of an 0603 resistor landpattern: #!/usr/bin/env pcblander [EMAIL PROTECTED]| [EMAIL PROTECTED]| include(footprints.inc) # macros [EMAIL PROTECTED]| include(constraints.inc)# common constraints [EMAIL PROTECTED]| [EMAIL PROTECTED]| num_pads = 2 [EMAIL PROTECTED]| pad_width = 1.1mm [EMAIL PROTECTED]| pad_height = 1.1mm [EMAIL PROTECTED]| padgap_x = 0.6mm # horizontal gap between left and right pads [EMAIL PROTECTED]| keepout = 20mils # center-silk to edge of pads [EMAIL PROTECTED]| SO(0,0)# 2 padded SO package, centered at (0,0) [EMAIL PROTECTED]| [EMAIL PROTECTED]| # write it all out [EMAIL PROTECTED]| mywriteland_and_source(0603.sfp) [EMAIL PROTECTED]| exit() Element[0x0 0 0 0 0 100 0x] ( Pad[-3346 0 -3346 0 4331 1200 4831 1 1 0x0100] Pad[3346 0 3346 0 4331 1200 4831 2 2 0x0100] ElementLine [7512 4165 -7512 4165 1000] ElementLine [-7512 4165 -7512 -4165 1000] ElementLine [-7512 -4165 7512 -4165 1000] ElementLine [7512 -4165 7512 4165 1000] ) If you wanted to change the pad gap from 0.6mm to 0.8mm, you could edit the line with padgap_x = 0.6mm, save the file and type 0603.sfp at the command line, and the footprint would rebuild itself. This works for any pcblander script. To create a footprint/source from an existing source, change mywriteland(...) to mywriteland_and_source(...), follow it with exit() (so pcblander doesn't try to execute the pcb footprint text), and put #!/usr/bin/env pcblander at the top. Run the file and a new one will be created with the commented source and footprint inside. The release, more examples, and additional documentation is at www.catalinacomputing.com/gEDA. Steve From May 1, 2007: Recently, I built a board using lots of custom surface mount parts, as well as a number of unusual through hole parts. When it came time to generate the footprints, I needed to design a number of new footprints. I looked into the tools available, and found some graphical tools and specialized scripting tools, but they either were hard to use, or I couldn't get them to build some of my footprints (sorry in advance, if I misrepresented someone's tool). To solve my problems, I came up with pcblander, which has been very effective for me. It uses human readable scripts as input. The scripts are pretty easy to follow, as they are mostly assignment statements and a few function calls. For those of you who use Darrell Harmon's footgen program, it has a number of similarities to that - I got myself started on pcblander by learning how footgen works. pcblander is quite flexible and extensible - if there's something missing, I should be able to add it in quickly (or if you prefer, you can do it by writing macros or, if you want complete flexibility, functions in perl).

Re: gEDA-user: New Tool for Making pcb footprints - new demo

There's a file called footprints.pdf with a sample output, so you can see what the macros can do (it's a big footprint with a bunch of footprints laid out together). There's a file footprints.lander that generates the layout in footprints.pdf. Type pcblander footprints.lander and you'll get a pcb file called footprints. With the new macros, you can generate pcb common footprints with only a few lines of text. Still, they are flexible enough to handle most common footprints, and you can add and tweak them by modifying footprints.lander or your footprint scripts.

Re: gEDA-user: Is the OrCAD Library Active?
You might want to take a look at Perl as well. It's been around the longest, and one of its primary goals was to do good text parsing (it has built in pattern matching and replacement). Ruby was actually written by a Perl affectionado, and has many of Perl's text handling attributes. Perl also has a huge library (CPAN) of available addon functions, and has lots of people who know how to write in it. Steve Arthur Baldwin wrote: Dear Patrick, Thanks for the update. There is a project labeled olib which stands for OrCAD Library and which is already part of the gEDA project. The problem with that side project is that it was designed for OrCAD version 4.0 (fairly old version). And the author says that there are several bugs in it. In my current study of Ruby, it seems like that language is well suited to parsing the native files of OrCAD (which by the way are ALL plain text files). The key to making olib complete is to choose a language whose strength is searching text and grouping the results of that text search into C++ based objects. The objects can then be manipulated to fit the object model of gEDA. Both Python and Ruby are fairly new to me, so I'm really expert in neither. But it is important to me to help develop a good solution to this problem. I can't see the point in spending 10K USD per seat for the latest version of OrCAD and then having to deal with the dongle on the parallel portjust to print out the schematic for an existing OrCAD project. Especially when every single data file in OrCAD is plain ordinary text with a structure similar to AutoCAD drawing files. There's no need to export from OrCAD into an intermediate format before conversion to gEDA...because of the fact that OrCAD uses plain text for all data. What will eat up our development time is figuring out what current structure methodology is used inside the OrCAD data files and then designing a parser to work with that structure. Ideally we should understand the structure well enough to be able to fix corrupted OrCAD data files during conversion. I'm looking forward to the day when users of gEDA will feel totally comfortable with converting in either direction...even with complex projects.

Anyway, I 've been working on a tool for doing footprints more easily, and your part looked different from the ones I've been doing, so I thought I'd try it out. I've updated the footprint with the pinout and hole changes (though it sounds like you've already added those changes plus an outline).

I haven't used it, so you should make sure it looks right to you. Thanks very much. There are a few issues with it, in case anyone else wants to use it. The more detailed doc is: http://www.molex.com/pdm_docs/sd/716612068_sd.pdf 1) The pin numbering is wrong. The pin numbering is based on the fingers in the connector running from 1..n/2 across the top and n/2+1..n on the bottom, so the pin marked 18 is actually 2 and the pin marked 2 is actually 3 and so on. 2) The mounting pins are plastic, so the holes should be unplated, I would think. I don't know if there's a standard for this in pcb elements. 3) I'm going to add an outline to the silk layer so I don't do something silly like put a resistor under the edge or recess it too far from the edge of the board! Thanks again to Steve for putting me on the right track.

Re: gEDA-user: Re: VMPlayer Image
I've been thinking about VMWare vs a live CD for gEDA, and it seems that both should be available. A VMWare image is great for all the reasons that have been talked about. A live CD is good for people who just want to try something (no installation required). I've been working on a live CD version which I would be happy to share (if people are interested and if there is a Web site I could post it onto). It's not perfect yet, but this is what it is. It's an Ubuntu Edgey Live CD with gschem, pcb , gnucap, iverilog, and the support utilities all installed. I pulled out some of the Edgey language support and the Evolution app to make room for the gEDA. Once you boot off of it, it also gives you the option of installing Ubuntu on your hard drive. (This has some interesting possibilities for VMWare users. You can boot it under VMWare, and install it to create a VMWare image.)

Re: gEDA-user: Re: VMPlayer Image
It's a full CD, so the ISO is ~700MB. It's got a complete Ubuntu installation kit on it, and the live CD part has a pretty good development environment and set of Unix applications (all from Edgey). If you let me know where I should put it, I'll put it there for you. Steve .
