The heuristics that spice-sdb uses to determine prefixes are =
complicated, and sometimes unpredictable. In the past, I=E2=80=99ve seen =
it decide that my D flip-flops needed the prefix =E2=80=9CD=E2=80=9D, =
but SPICE had a hard time interpreting a flip-flop model as a diode ;-). =
I avoid this with the =E2=80=94nomunge flag (gnetlist -g spice-sdb =
=E2=80=94nomunge =E2=80=A6).
The add-on netlist back end at https://github.com/noqsi/gnet-spice-noqsi =
gives you much more control of prefixes and connections, but it=E2=80=99s =
not so well documented.
