Re: gEDA-user: Slots and tragesym

[Steve Meier <smeier@xxxxxxxxxxxxxxxxxxx>]

Craig,

from the 7400-1.sym

numslots=4

slotdef=1:1,2,3
slotdef=2:4,5,6
slotdef=3:9,10,8
slotdef=4:12,13,11

slot=1

This tells us that this symbol has 4 slots.
The pins for slot 1 are 1, 2 and 3 and for slot 2 they are 4, 5 and 6.

The graphical pins themselves have an attribute pinseq=3. This tells us
that that particular pin has its pin number replaced with the third pin
number in the desired slotdef.

for example, slotdef=4:12,13,11 the third pin is pin 11

When you select the symbol after it is dropped into a schematic you may
set at the schematic level a slot attribute. For example slot=2.

Best Wishes,

Steve Meier
