Version 97.4 of HSpice has an eye diagram demo in the demo/awaves/demo
area. Basically, you create a sawtooth wave with the same period as your
clock period, and use this sawtooth wave as your X axis. The X axis can
then become a percentage of clock period (if you make your sawtooth wave
go up to 1V).
