Hi!
I setted up a simulation with microstrip on a 4L process (PCB) to simulate an amplifier.
After simulation I wanted to do an EM Extract simulation. The transistor model that is used for the simulation is a spice model that needs a specific DC bias.
Therefore I setted the frequencies from 0 to 8 GHz and changed the transistor properties to "Use convolution if active".
If I simulate the DC bias point is not used and I always see a strange behaviour explainable because both DC sources (DCVS) output zero current (logged via annotations).
How can I set the DC bias in EM Extract mode?
