Re: gEDA-user: How to make a ground plane in PCB and attach all GND and VSS nets

[Rob Butts <r.butts2@xxxxxxxxx>]

   Actually, to get the GND net to tie in with the VSS net do I have to go
   down into each symbol in gschem and replace net=VSS:8 with net=GND:8?
   Same with Vcc and VDD?

     In PCB there's no real difference between a signal plane and a
     power/gnd plane.  Just set up any 4-layer board.

     I've never had much luck getting the autorouter to do this.  I
     usually
     pre-route all the power/gnd connections because I want them to have
     short fat traces, then let the autorouter do the signals.
