Maybe I am missing the obvious, but I am trying to simulate a frequency dependent resistor within a subcircuit. The top level circuit will do a S-Parameter simulation, and I am trying (without success) to pass the frequency down to the subcircuit so it can simulate a frequency-dependent resistor. I have tried to use the equation block in the top level circuit to create a new variable name, but no success in passing it to the subcircuit. It is odd that I can display this new variable in a graph or table, but I cannot work with it in a simulation.
ex: Equation 1
I can create the Cartesian Graph or a Table of Fract (and frequency), but cannot make it control behaviour of a component, in that top level circuit or any subcircuit.
