I am simulating a parasitic capacitance extracted toplevel circuit with UltraSim 6.0. I have a problem of DC operating point calculation. UltraSim says in output log that "DC simulation finishes without reaching steady state" at the beginning of transient simulation. Then all bias voltages begin to make their settling behavior to their final value, but it takes a lot of transient simulation time. Is there a method at UltraSim to calculate steady state operating point at the beginning of transient simulation correctly?
Thanks in advance,
