Re: gEDA-user: PCB Netlist syntax
I managed to edit the netlist file manually (in gedit) and added the word 'Power'. Seems it is case sensitive _and_ tab sensitive. To summarize, the syntax of the style allocation should be: netname style_name pin pin pin where stylename is Case sensitive. e.g. "Power" worked; "power" did not... Yes it would be good if gnetlist could read some attribute like routestyle or something... But adding it manually isn't such a hard job at least for small boards...

gEDA-user: PCB Netlist syntax
What is the syntax for allotting a routing style to a net? I saw the syntax here: http://pcb.gpleda.org/pcb-cvs/pcb.html#Netlist-File and http://archives.seul.org/geda/dev/May-2008/msg00120.html I created the netlist using gschem2pcb and then edited it using a text editor, adding the word "power" just after the net GND in the netlist. The PCB log window reported no errors when I hit 'O' to optimise the rats nest, but the autorouter ignored the route style. If, instead, I use -power I get: WARNING! Pin number ending with 'R' encountered in netlist file Probably a bad netlist file format Can't find pin POWER called for in netlist. Is there a caps/no-caps requirement? Or Tab separation? P.S. Double checked that the correct netlist is getting loaded, and I Do have a route style called 'Power' with fatter trace widths.

Re: gEDA-user: PCB Netlist?
SPICE has no understanding of pin numbers *at all*. Its abstractions are grounded in IC design where you have no pin numbers (at least internally). You'd have to provide a file mapping positional netlist connections to pin numbers. Another advantage of using a *flexible* schematic capture tool rather than a specialized one. In gschem you can specify both pin numbers (pinnumber= attribute) and pin position in a SPICE netlist (pinseq= attribute). I am starting to see the picture now, I am playing with gschem right now on my server. I do see that this is a better way to input if it is going to go to layout afterword, but yes you do pay the price up front to save time using a netlist to help with the PCB layout. It is a nightmare trying to check a complicated layout against a schematic, just praying that you aren't missing anything. I switched over to all Macs for workstations and lappys. The only PC archetecture that I have up and running now is the server that runs FreeBSD. I might want to install a fresh copy of Ubuntu on my wife's lappy. I was not able to get X11 to work right with fink. Mac ports seem to support more applications and is more familiar to me since I use FreeBSD.

I do schematic capture for simulation, printed circuit design, and VLSI design with gschem, using a variety of design flows, whatever the customer wants. But LTSpice is specialized for simulation, so it doesn't need the extra capabilities gschem has, and there are therefore fewer opportunities for confusion. > I like PCB better than all of the other PCB CAD packages out there. > Very powerful, and it does not have a real steep curve just to get up > and running. > Thanks, > Chris Maness > > References > > 1. mailto:j...@noqsi.com > 2. http://www.brorson.com/gEDA/SPICE/intro.html > 3. http://www.noqsi.com/ > 4. mailto:j...@noqsi.com > > > ___ > geda-user mailing list > geda-user@moria.seul.org > http://www.seul.org/cgi-bin/mailman/listinfo/geda-user John Doty Noqsi Aerospace, Ltd. http://www.noqsi.com/ j...@noqsi.com ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
