Hi,
I have a question about a spectreRF error when running harmonic balance pnoise. for a VCO.
It was able to run a pss succesfully, but when it starts running the pnoise, I get the following error.
-------------
Error found by spectre at freq = 100 kHz during PNoise analysis `pnoise'.
ERROR (SPCRTRF-15397): The pnoise analysis was skipped since the collected total noise is zero.
Analysis `pnoise' was terminated prematurely due to an error.
-----------------
Interestingly, the same pss/pnoise setting can run successfully with the same circuit/vco but at a low vco speed setting.
I was not able to find any information on this error code. Any help is appreciated. thanks
