Hi Mike,
Do you have support for the behavioral sources to provide power functions on the roadmap?
Right now, I run into issues (Timestep too small) if I try to define a behavioral source (R, V, or I) – with the R/V/I value defined based on a power waveform (i.e. R = V(vsys)**2/V(Px), where ‘vsys’ is the net on one of the behavioral resistor terminals (the other to GND/0) and V(Px) is an arbitrary Power waveform defined by the voltage output of a configured Voltage Source.
Having these non-convergance issues and the lack of Vprxover are preventing me from moving over to QSpice from LTSpice.
