Expert Opinion - Query 15 (Ground bounce)

How do you eliminate Ground bounce?

Ground bounce is a common problem seen in high speed signal designs. The main reason we see ground bounce is because all the signals share a common return path. So, we see that sharing a common return path is the culprit. Is it that we can eliminate common return paths? No, in practical scenarios it is not possible. So, the only way here is that whatever the return path that is present for the signals must be proper without any discontinuities. If there is a discontinuity for a particular signal, it might effect the entire return path as return path is shared.
