Re: gEDA-user: Symbol with 20 pins for a module of 40 connections

I want to connect each of these pairs.  My footprint has 20 pads and
20 pins with the following numbering.  Again the primary objective is
to connect each pair within the symbol that represents this module and
only have 20 pins visible on the schematic.
Pad   Pin
1        21
2        22
3        23
4        24
5        25
6        26
7        27

20      40


I think you are wanting a pad (no hole) and a via(with hole) to connect to a schematic in/out. If so, you can number them the same in your footprint. Then you have just twenty numbers. You will then have a pad 1 and a pin 1. The netlist will then require you to connect them with a trace on the pcb -- think of that pcb without your module added though...

Your schematic for the module will have no connection to the mother-board unless you put hierarchy attributes on it. You've not mentioned wanting hierarchy. Just make your footprint have the same number for each pair of in/out pin and pad, then make a symbol with that same numbering with twenty pins total.
