[Xcircuit-dev] Multiple-gate chips in PCB netlists

[Bryce D. <br...@tl...>]

I was hoping to draw a schematic with a quad op-amp, based on the quad
NAND example in the quadparts library.  However I cannot get the quad NAND
to produce a usable pcb netlist.  I have filed a few bugs on Source Forge
describing the problems I'm seeing.  Basically:

1. I can't find any way to specify power and ground connections in a
multigate chip.  Maybe one of the instances should have power and ground
ports, and the others should not?

2. The pcb netlist output looks like U1-3-10, meaning part number U1, gate
number 3, pin 10.  This cannot be parsed in the pcb software, unless I
change it to just U1-10.  I know how to do this with a perl script to fix
up the netlist, but is there a better way?

I'm using xcircuit 2.5.2.  Later versions are crashing on startup with an
XQueryColors error.  I filed that one too. :)

Thanks,
