Not entirely clear how to add NPN models to a spice file so gnucap can
simulate it.
Q1 1 2 3 NPN
Says 'Q1: can't find: NPN'
Models are separate in spice files.
Seems that this needs to be added in the schematic as an "A"
(annotation?) block.
[master] tom@tp:~/rai/spice$ apt-file find 2N3904.mod
apt-file find 2N3904.mod
geda-examples: /usr/share/doc/geda-examples/examples/TwoStageAmp/models/2N3904.mod
So the component needs a value=2N3904 attribute.
C 43700 45200 1 0 0 npn.sym
{
T 44300 45700 5 10 0 0 0 0 1
device=NPN_TRANSISTOR
T 44300 45700 5 10 1 1 0 0 1
refdes=Q1
T 44300 45500 5 10 1 1 0 0 1
value=2N3904
}
The schematic then needs a separate model box to trigger inclusion by
gnetlist of the model file into the final spice file.

}
