I am trying to measure the phase noise of my circuit output clock at rising edge and falling edge separately.
I am able to measure the overall phase noise of the clock using PSS/PNOISE but not separately.
Could anybody please tell how to simulate that in SpectreRF.

In reply to RFQuery:
This would be covered in the "jitter" mode of pnoise. You need to use the "PM" mode of that (which happens all the time when simulating a driven circuit, but is a choice for oscillators). In PM jitter, you specify a threshold, and then you'll get the jitter computed at each transition.
