thx a lot!

PLL Phase Simulation actually is not that much difficult as you think. Using Matlab or Cadence both can do.  Basically  check noise from individual block first, then build PLL noise model(Matlab or Cadence) to check the whole loop simulation. The critical thing is you have to identify where is noise dorminant from and how to adjust the loop parameter to get the optimal results.

Hopefully it helps to you.

有没有关于建模的论文呢

I have ever built the circuit level model and matlab model as well.  For circuit level, it is more convenient to use. let me try to pack it and upload later if many ppl interested. Otherwise, don't waste my time.

I do think so. But the problem is even I get the phase noise for each module like PFD, CHP, VCO, how can I add it into the loop, you know, the phase noise is a function of frequncy.Could you show us how to do it?Thanks.
