Title: PSS convergence on divider
Post by lianggu on Feb 15^th, 2008, 11:37am

Hi,

I run PSS simulation on a divider by 2 (just a DFF with negative feedback). But it always can not be convergent even if I set large tstab and steadyratio. Can any one give me some advice?

The period that SpectreRF requires is the period at the output of the divider.

Thanks a lot! After I change "beat period" to the period of divider output, PSS can be convergent!
