Thanks for your reply.
Could you tell me some detail?
Actually, I made a phase domain behavioral model of pll with component in analogLib. I used vccs to model the charge pump, vcvs to model an amplifier. I want to simulate the noise shaping effect for a given noise source, like resistor in the loop filter or charge pump.
Is XF simulation able to get what I want? How to do that?
Thanks,
