Slotting is a fabrication concept. SPICE doesn't understand slotting.
Don't use it in your sims.
Hi John...
Thanks for the reply. I thought the idea of gEDA was to make a
complete
package, including fabrication and simulation. Actually, it's not
SPICE
that's complaining either - it's the netlister which isn't happy.
Since SPICE doesn't deal with slots, the netlister doesn't know how
to tell it what to do.
gEDA *is* a complete package: it can compose schematics for
simulation or for fabrication. But simulation is device and
subcircuit oriented, while fabrication is part oriented. They aren't
the same thing, and I think trying to do this mapping would make
symbol creation incomprehensible to many. Note that if you download a
SPICE model for a quad opamp from a manufacturer you'll actually get
a model of just one section. It's a common problem, not specific to
gEDA.
You can spend $100k/yr on EDA and still struggle with this issue
(been there, done that).
