Thanks RFICDUDE,
I took the first step with your help and now I think the PSS+PAC sim shows correct results.
However, I see some discrepancy in Phase noise sim.
Here is the issue: assume I have only one 1GHz large signal/clock (I removed the other one to simplify the issue) in the circuit and I would like to measure the phase noise on that.
two methods that I tried and observed different results are:
1) PSS, beat freq=1G, output harmonics=3 Pnoise, sweeptype=relative, relative harmonic=1 2) PSS, beat freq=0.1G, output harmonics=30 Pnoise, sweeptype=relative, relative harmonic=10 the phase noise at 100MHz offset is low for method #2 around-171dBc but I think method #1 shows correct phase noise.
what do I miss in method #2 with 10X lower beat frequency that results in improper phase noise?
Thanks, Saeed
