Ken:
The oscillator comprises a MEMS oscillator (verilog-A model) with a Q of 10000, a trans-impedance amplifier and an AGC.
The PSS analysis converged in every simulation, but the pnoise analysis failed for most of my simulations with the same error message as I posted before. Sometimes, when I changed tstab to some value, the pnoise analysis completed properly, but these situations are very rare. And I found no relationship between tstab and a successful pnoise analysis.
Thank you.
