gEDA-user: Footprint/symbol generating scripts + question
I'm working on a largish project involving all sorts of tiny SMD stuff, such as BGA's, connectors, ULLGA6 and similar PCB footprints. In order to save myself work, I cobbled together a few bash scripts to generate the regular pad patterns. These can be manually edited afterwards, e.g. to define an outline, or to add or remove pads. This one creates one or two columns of rectangular pads: http://www.linetec.nl/electronics/smdmake And this one makes a BGA footprint, with an optional outline: http://www.linetec.nl/electronics/bgamake If anyone thinks they're useful: enjoy. And of course comments and/or improvements are welcome too. The most notable thing is that I decided to use microns rather than millimeters, since floating point operations aren't exactly bash' forte. I also have scripts to generate a gschem symbol (two columns of pins) based on pin names and numbers copy/pasted from PDF datasheets; another one creates a list of nets by the same method -- but those two aren't quite finished yet, and require some more manual editing. Still, they saved me a huge amount of time, and also prevent errors in pin name or number designations. If anyone is interested in those, I'll try to complete them and put them online as well. One last question: the project I'm working on has several schematic pages, with several nets spanning multiple pages. For me, this is the first project of this size, and I wondered about one thing: Are there special symbols to indicate nets connected to other schematic pages? In the reference design on which this project is based (probably made in OrCAD), those nets have double arrows, but I can't find anything similar in gschem. So now I have quite a few nets ending in little red squares, giving the impression that they're open-ended. The actual connection is there, of course, so it's more of a cosmetic issue, but I have the feeling that this is not how it's supposed to look.

The bus could be labeled with the sheet the nets connect to. All this is just cosmetics, though. -- Stephan ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
Re: gEDA-user: Footprint/symbol generating scripts + question
(having not seen this post) I created something similar yesterday in python. It only does SMD dual column footprints with an outline - and at the moment only takes mm. I'll push it to github or something like that if folks are interested. I assumed at the time that this sort of tool must get made all the time - but not having net access to search for one I thought I'd have a go at it too :P On Wed, Apr 6, 2011 at 9:22 PM, Stephan Boettcher [1]boettc...@physik.uni-kiel.de wrote: Richard Rasker [2]ras...@linetec.nl writes: One last question: the project I'm working on has several schematic pages, with several nets spanning multiple pages.
