Analog_cha,

  Have you tried the jitter_meter from the bmslib? It calculates
the jitter directly from the transient output using a reference clock.

                                                      Best Regards,

It doesn't relate to ocean scripting, and It ASSUMES you are running Cadence tools.. -- a full install of which will have a copy of "bmslib".

you place the "jittermeter" model in your schematic.. and run the simulation.. If I recall correctly It captures a number of periods of the input signal and calculates some statistics on the variation in the period. (or did it need a reference clock? )

-- but my concerns have been more with validation of pll operation than measuring the jitter.. usually the designers do that..

But I find I can do a heck of a lot of results analysis in a verilogA model, rather than hoping to find a way to post process the results and get the right answer.

how to setup source and analysis for PRBS with spectre?

Assume a  transmission line or its S-parameter data to be tested,  wanted to simulate eye diagram  at the output of it.

thanks

thanks.
