I am simulating an RFIC oscillator. An on-chip inductor is represented as an s-parameter data file.
I am oberserving differences between harmonic balance simulation, transient simulation, transient assisted harmonic balance. The three approaches each produce different results for DC current consumption, and therefore produce different amplitudes and frequency of oscillation. The differences are significant.
Advice regarding the reason behind these differences and potential solutions would be appreciated.

If you don't have it - add a data line for 0 Hz in the S-parameter file.
Example (Touchstone):
Format will depend on what file type you have and which format you're using (RI / MA etc).
This may not solve your problem but it's the first thing you should check.
