gEDA-user: How to deal with single/dual parts?

[Bill Gatliff <bgat@xxxxxxxxxxxxxxx>]

Guys:


I can get TI's LittleLogic NAND gates in single (SN74LVC1G00) and dual
(SN74LVC2G00) varieties.  At the schematic level, however, I'd prefer to
just have a NAND symbol and a separate symbol for the power pins.

One way to solve this problem is to have a symbol named sn74lvc1g00.sym
for the single-gate case, and sn74lvc2g00-1.sym and sn74lvc2g00-2.sym
for the two gates of the dual-gate part.  Then just pick--- and
re-pick--- the right one as I sort things out at layout time.  (Add one
symbol each for the power pins).

At the moment, I really don't want to deal with much back-end scripting
to make selection more automated.  And the slotting feature has left a
bad taste in my mouth in the past due to errors in the symbol.

Given all that, is the three-symbol approach described above the most
straightforward way to deal with my situation?  Or am I missing
something obvious?


b.g.
