Dear all,
If I want to simulate eye diagram in hspice, how do I do?
Are there other tools simulating eye diagram?
If you have these information, can you help me?
Thanks.
lots of methods
1. use cssope for waveform viewer. It has a eye function
2. print the signal in hspice and plot its eye with matlab, before this you must write a matlab script first.
3. write a pwl source in hspice netlist such as
veye aaa 0 pwl (0 0 100n 100n r)
the 100n is the eye width,
after simulation completed, open the waveform by awave
and change the x-axis to v(aaa)
then polt the signal eye

In the calculator option of most of the tools I've found Eyediagram plotting option on which it will be plotted..I've found them in Cadence Virtuoso Analog Design environment and Mentor Graphics - System vision.
