Interesting. Stuart seems not to have implemented refdes "munging" for all of the components he lists at But my experimental spice-noqsi backend (, intended to be mostly compatible with spice-sdb, gets the resistors right for this case. I seem to have implemented Stuart's design better than his own code does here ;-)

The only incompatibility in this case is that spice-noqsi doesn't identify GND with node 0. This is intentional, to allow you to model parasitics in the interconnections between subcircuits. For simple simulations, I just connect GND to node 0 through a 1 ohm resistor at my simulated "power supply". Note that this method requires an explicit ground connection to subcircuits. If you want the old behavior, make a GND symbol with net=0:1.

I guess I should no longer consider this back end experimental. I've been using it intensively for months now. Time to write some documentation.
