hi, everyone
I have a problem of simulation jitter of PLL in cadence 5141.
when i was running pss, some error appeared:
Error found by spectre during periodic steady state analysis `pss'.
`V1' is a periodic input signal, which is inconsistent with autonomous
circuits.
PS: V1 is the reference source of the PLL.
I think PLL should be a driven circuit but an autonomous circuit.
I want to know Whether I should run pss and pnoise to get the jitter of the PLL and how to do it.
