Maestro - Intersymbol Interference (ISI) Jitter measurement

firebolt3

I am trying to measure ISI jitter using delay function between PRBS pattern output (includes DCD+ISI jitter) & Clk pattern output (includes DCD jitter only). I need delay seperately for rise & fall edges. For Rise2Rise delay, function should capture only delay between rising edges of both signals at the same time, not at different times. Same is applicable to fall delay also. This delay, either Rise2Rise or Fall2Fall, will eliminate common DCD jitter and left with ISI jitter only. But my delay expression is not working properly. Below image (shared in link) clearly shows what I am trying to measure. Please help.

    If this is urgent, you should contact customer support, as these forums are done in our own time (including those of us like me who are Cadence employees). The forums are not a substitute for customer support.

    I can't see your picture as it's on a google drive which doesn't work for me (might be because it's blocked for us).
