I'm simulating a circuit that has a few noise contributors. After running an S-parameter simulation, I can display SP.port2.NC.vnc and SP.port2.NC.name in a table where I see all noise contributors and their indexes.
When sweeping some parameters in the circuit, the noise contributors change their indexes as their noise voltage values change. Is there a way to know the index of a particular contributor so that an equation could perform some numerical analysis on its output noise voltage?
Index Sp2.port2.NC.vnc Sp2.port2.NC.name
0 1nV _total
1 0.867nV AMP1
2 0.5nV AMP2
Sometimes AMP1 and AMP2 switch places. I'd like to be able to tell when that happens and be able to always know the index for AMP1, for example.
