I've designed CRC(clock recovery circuit), and want to measure the jitter characteristics using Hspice.

I'm not familiar with HSPICE, jitter, eye diagram, etc.

Here are my questions.

1. I'm using PRBS patterns for the input data. Are they right to be used in my case?

2. I'm using Custom Waveview for the simulation of my circuit. I can check the eye diagram, but I don't know how/what I should measure or interpret the eye pattern.

3. Do I have to inject noise to the supply voltage? How?????

4. What should I check for the performance evaluation for the clock recovery circuit? Is it ok if I check the eye diagram only?

Is there anyone can help me?
