Re: gEDA-user: hierarchical design and slots

[Steve Meier <smeier@xxxxxxxxxxxxxxxxxxx>]

Britton,

you make one symbol lm324.sym.

for each pin you add a pin sequence.
typically you use the 1st slots pins and add a pinnumber=2 to the pin as
well

then you add an attribute
slot=1:2,4,6,8
then another attribute
slot=2:1,3,5,7

picking a slot at the schematic level substitues the pin numbers from
the slot attribute

have fun,

Steve M.
