Dear all,
I have a simulation of an amplifier circuit (PCB) that consists of some lumped parameters and a nonlinear device.
As soon as the EM Extract block is enabled the DC bias (DCVS block) voltage does not apply any current and thus the transistor model (SPICE) does not work.
How can I fix this problem? (For now I include DC into my simulation)
Second problem but not as important as the first one is that as soon as I hit run the EM Model gets overwritten and therefore I cannot change things before simulation.
What I want is to set the ports to connect to lower and draw a GND plane beneath the circuit because I have 4L substrate.
