What kind of simulation are you aiming to do? The answer is somewhat dependent on that - it may be that a simple small-signal noise source is sufficient (if doing, say, pnoise analysis) - or you may need a larger-signal source for doing transient. Or you may be doing transient noise?

I think some more details are needed before an answer can be given.

Thanks,

Andrew.

I'm not familiar with a "stressed eye" simulation. I've found a few casual references to it from a google search, but didn't have time to research it fully to understand what you mean (I can guess, but I'd sooner know exactly what you mean).

Can you point me at some references so I can understand precisely what you're trying to do? Or if not, explain it here?

Regards,

Andrew.

What type of jitter do you want to realize ?

You can create PRBS with jitters similar to the above by Verilog-A.

See　http://www.designers-guide.org/VerilogAMS/

And the followings are useful although they are VHDL-AMS.

You might also want to take a look at the models that generate jitter in http://www.designers-guide.org/Analysis/PLLnoise+jitter.pdf
