pll spur

I want to simulate pll spur by using verilog-A file. simulation tool is spetre. it costs a lot of time. Firstly, I do the transient simu, then to do the fft. Is there any good way to do it? appreciate.

Hi,
Plot the power spectrum density of your signal using the psd function of the calculator. You'll be apple to see the spurs.

got it. appreciate
