Hi,
I'm simulating an oscillator with a source input to kick-start the oscillation. I tried to plot the the frequency of the output signal Vs. the control voltage. But I have read several posts saying that it couldn't be done with PSS anlaysis. Instead, it could be done using harmonic balanced simulation (HB) as it has "Semi-autonomous" mode.
I have tried HB analysis several times but there was an error :
No convergence achieved with the minimum time step specified. Last acceptable solution computed at 0s.How to overcome this error?.
Now, knowing that the circuit works in the range [1-4 GHz] how to set-up the harmonic balance analysis correctly?
I'm using virtuoso 6.1.7
hope anyone could help me.
thanks.
