Hi Balamanikandan,

Check out in the Stimulus configure (button on the GUI)
You have option to skip the no of initial bits

* Dry run and estimate the no of cycles for the waveform to settle -- skip 
those many cycles in the eye
or
* Replace the capacitor by the equivalent capacitive resistance 
Xc=1/2(Pi)(f)(C) and simulate -- this is mentioned in the Mentorgraphics user 
web-page

Regards
Ck.,

Subject: [SI-LIST] excluding the initial delay- eye diagram

hi
     I am using hyper-lynx. I am trying to get the eye diagram for a
particular circuit.

     The circuit has a capacitor and it causes huge delay to settle the
signal (stable form).

     The eye diagram obtained through the simulation includes the effect of
initial delay also.

     Is there any possibility to see the eye diagram excluding the initial
delay caused by capacitors?
