We use both SigXp and PCB_SI. At this point, we are extracting the net topology off of the schematic through constraint manager. When we try to extract any net that has one of these test nodes, SigXp complains that all discrete components need models and bails out.
I am including a little .gif of the resistor nets. In this particular shot, the three components are labeled RN1,2,3 but in reality, they would all be part of the same network... Notice the pin numbers.
