hi panyi,

thanks for your informative advice! after seeing the picture, i've got another questions:

1. As i know, there are several kinds of model to describe transmission line, such as s-model, w-model, and t-model in the pic1 as as well, then which one would be most apropriate for the usb cable modeling?

2. as depicted in the pic1, it should be 52 tline block to generate 26ns delay, am i right?

3. what's the desription language used in pic2, spice or spectre, or anything else?
