I was trying to simulate my circuit (using PSS/PNOISE) which has mixer for downconversion.
The clock for the mixers are coming from another circuit block.
When I simulate with my clock source circuit it takes a lot of time to simulate the PSS.
So I want to simulate the clock source separately and capture the output waveform in a .PWL file.
This .PWL file I want to feed the main circuit for doing PSS/PNOISE analysis.
I am confused how it will work. Can anybody tell how this way of simulation will work with PSS/PNOISE. How this will affect the accuracy of the PSS/PNOISE simulation.
