Hi, Johnlin,

As I know Prof. Jiayuan Fang from the State University of New York at
Binghamton is leading a group in developing such a software which I
guess might be of very help to you.

Actually in a presentation here at Apple, he demonstrated a simulation
of K5 processor(as I remembered). The animations showed the wave
travelling both on a user designated wire and between selectd two
adjacent power/ground planes.

The program can run both on workstations and on PCs. And the PC version
I believe is for sale. You may check with him at fangj@binghamton.edu.

I hope this information can be a little helpful to you.

Good luck,
