PSS simulation of Oscillators

Hi,

I am simulating an oscillator. In transient simulation, I am getting 10GHz of oscillation, while i am getting 20GHz of oscillation in PSS / HB method. I followed all the steps as mentioned here. (https://community.cadence.com/cadence_technology_forums/f/rf-design/40949/pss-simulation-for-vco)

You've not given enough information to stand any chance of diagnosing this. Please contact customer support.

Dear Sumit Dash,

As Andrew mentioned, the information in your post really doesn't allow anyone to provide any specific suggestions. If you can share more information about your oscillator (type - harmonic (i.e. resonator based), ring, high-Q/low-Q, expected oscillation frequency), simulation settings for your transient and pss/pnoise simulations, and output logs with any error messages, I'd be willing to provide a few thoughts if you are interested.
