I am continuing to have problems with multi part symbols. Here
I have an op amp define as thus:
v 20100214 2

}
T 700 600 8 10 1 1 0 0 1
refdes=U?
T 700 1200 5 10 0 0 0 0 1
description=operational amplifier
T 700 1400 5 10 0 0 0 0 1
symversion=0.1
T 200 1450 8 10 0 0 0 0 1
footprint=soic-08-d.fp
T 700 1000 8 10 0 0 0 0 1
file=./spice/OPA333.lib
When I try to use this op amp, the pin number show up wrong on the
schematic. For slot 1 they show up as 1,2,1 (not 3,2,1). When I try
slot 2 I get 5,6,1 not 5,6,7. Likewise spice back end also blows a
gasket trying with the pinseq numbers. I thought the pin seq refers to
which position in the spice parameter list the pin refers to?
I was going to see if I could fix up the spice-sdb backend to handle
putting multi part symbols back together, but I think something might
be more fundamentally broken inside gschem. Do folks have any
thoughts?
