need your help!
thanks!
 

Re: how to simulate the noise of close loop pll with Spectre

One one would be running transient simulation, measuring time jitter and transferring it into phase noise.

You may also try to run PSS with tstab longer than PLL lock time and run PNOISE.

Hi all,

Could you please Elaborate. That issue id very interresting for me.

Thanks in advance.
 

I could never finish this simulation. It always crashed because of insufficient memory or so. If you can make it I'd also be interested how to do it.
