gEDA-user: How to save results in txt file?
Hi all. I have results of DC sweep. Can plot it, but cant figure out how to save it in txt file (tab delimited for example, or other), for plotting in something other than ngspice. Thanks in advance.

In Gnucap, you direct the the command like a unix command .. dc R12 10 100k decade 3 the-data-file The file is whitespace delimited, and can be read by most spreadsheets and plot programs. Spice uses something called a rawfile, which has in its own format. You put -r rawfilename on the command line. I don't know how to directly get a file that works with programs that are not specifically written for spice. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

You can use the ascii format of ngspice: insert set filetype=ascii into your simulation file. Or if you're using python you can use my import filters: http://www.h-renrew.de/h/python_spice/spicedata.html Or if you're using octave you can use another import filter (not as good as the python version) http://www.h-renrew.de/h/de_spice/de.html regards Werner ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
gEDA-user: Footprint flags for pad shapes
Hello, I found some hint in the land patterns tutorial about the meaning of flags for pad shape. But I realized the following: 0x0100 - square (match with .pdf) 0x0900 - square (I found in a QFN package footprint) what shape should it be? 0x - rounded (match with .pdf) 0x0800 - rounded (the .pdf says: octogon) Furthermore, the latter two for x=y seems to be a circle, not a rounded square. Can I create a pad like this? /\ || || || \/ (Sorry, you may need to view with monospace fonts) Thanks, /sza2 ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Don't know why. Round means circle, not rounded-corners. When width!=height you get round-ended lines. Can I create a pad like this? Not with a single pad, no. If you have the time and want to add support for the octagon flag to pads, go ahead. Just beware you have to fix the autorouter and DRC modules too. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
gEDA-user: Wiki pages
Hello people. Once in a while, I have the urge to save a page which seems too useful to download it every time I need it. I tried to do that with a couple of the gEDA wiki pages, and found that its format doesn't really allow to do that (something I didn't notice on other sites - at least it doesn't work with Firefox 3.0.xx). I may be wrong - I'm not an HTML expert, but I noticed a couple of issues: 1) The logo has an absolute link: http://geda.seul.org//graphics/navlogo.png 2) It seems most of the problems are caused by the ':' in the URL. If I do a seach-and-replace (geda: by geda_) all links work in the saved page, and all images show (which they didn't before the change). I'm doubtful if the ':' is legal (even though it works). Normally a ':' in a URL is the separator between URL and the port. (eg. http://my.url.org:8080) 3) This also works for CSS: before the replacement, css files were not loaded correctly. 4) Neither CSS validation (2 errors) nor HTML validation (33 errors) accept that page (geda:gsch2pcb_tutorial). Most are very minor errors - but they may contribute to the save problem. Note this is not criticism, just observing a couple of points which might improve the usability of the docs. ... and I offer my help if wanted. John PS: My workaround is to save it as PDF from the browser - which works reasonably well, but I prefer HTML. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

gEDA-user: PCB: May inserting new layers destroy my layout?
OK, maybe a silly question... Most part of my DSO board is finished now, I have to redraw some traces and to draw power planes. It may be a good idea to use more layers, i.e. to divide component layers in fast and slow signals, and to divide ground in AGND and DGND with different colors. But for this I have to move layers, and maybe to insert some new layers. Is this operation save for latest pcb snapshot pcb version 20081128? Of course we should assume it is, but I think only a few people will try this operation. And there was a problem about two years ago when I started using PCB.

Re: gEDA-user: PCB: May inserting new layers destroy my layout?
The only bug I know of involves moving thermals on vias to the new layers. You could build the latest git version just for this operation. Of course, save a backup copy of your board *anyway*. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

OK, now I remember the old bug: http://www.geda.seul.org/mailinglist/geda-user92/msg00121.html I guess it is fixed for version 20081128. Of course, save a backup copy of your board *anyway*. Sure -- but some bugs may hide itself, maybe until gerber export. To be safe I may export gerbers before and after I insert new layers and compare the gerbers. But of course the gerbers may be identical, while PCB operation fails after insertion of new layers. It's a dangerous world... ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
