I am trying to run a large signal simulation of an RF Switch after running an initial transient as the internal voltages need to be set and attain steady state before I run power through the circuit.
I have tried using HB with a tsab and had convergence issues. I also tried pss with no luck ..
What is the best way to simulate such a circuit ?
There's not really enough info to go on. You didn't show which version you're using, what the analysis setup was, or what the error message in the log file said.
I suggest that going to customer support is probably your best bet.
