Thanks, I have found the way. There is a function eyediagram in the calculator of Cadence spectre.
May I ask an other Q?
Since my input signal is a RBS(random bit stream), I was reqired to set the period, rise-time,fall-time,delay.
For example, in the codition T=50ps,Trise=1ps,Tfall=1ps, I wiil see a very large overshoot.Should I owed this to the too-short Trise and Tfall, or my ckt?
Thanks
