I m trying to find out the noise contribution of the pulse swallow diver in a pll. As the division ratio is very high (10000), it is very difficult to simulate the noise using pss+pnoise. Is there a way to simulate the noise efficiently?

thanks

Hi Frank, thanks for the reply.
If I reduece the division ratio,  I would also decrease the noise sampling frequency. After all I get different strobed phase noise. Can I mutlipy the noise by the factor I reduce the ratio, and say this is the phase noise I should get at a high division ratio?
