Dear All,
I am simulating a LC VCO in PSS in Oscillator mode, and I encountered a no convergence problem if I enabled the "Calculate initial conditions (ic) automatically" option:
But if I disable this option like the next image and give a initial condition through ADE L>Simulation>Convergence Aids>Initial Condition manually, PSS will convergence.
The same situation happened when I simulate transient analysis with "Calculate initial conditions (ic) automatically" enabled. And again there is no convergence problem if I set a initial condition by myself.
Could you tell me what's the difference between "Calculate initial conditions (ic) automatically" and set initial condition through Convergence Aid by users? Is that reasonable if I disable "Calculate initial conditions (ic) automatically" and give initial condition through Convergence Aid?
Regards,
Clara.
