DCDC buck converter PSS/PSTB simulation for gain/phase margin check

I am newbie for spectreRF simulation. Anyone can help me check my simulation methodology correct or not? Thanks a lot.

I am going to run full schematic simulation (not veriloga model)

    Yes, because your switching frequency is an integer multiple (16) of the PSS fundamental. You can fit a whole number of cycles of 1.1MHz into a cycle of 68.750kHz, which enables it to do the Fourier analysis of a periodic waveform.

    Regards,

    Andrew.
