Weiheng,
You may think that this is a simple question, but not on this mail list...! :)
One nanosecond is about equal to six inches of trace length in a typical FR4
PCB, so a 1-inch trace would equate to ~167 picoseconds.
Let the fun begin!

Andy Green

Hi,
I have a simple quesion. Usually, how many nano-seconds does 1-inch-trace's
propagated delay equal to? Thank you.
Regards,
Weiheng
