Eric Bogatin explains the figures of merit in the time and frequency domain, and he steps through how to get a rough measure of the highest frequency components in a signal.

Yuiry Shelpnev argues that simulating a link in isolation from the rest of the board (localization) is probably the most important requirement to simulate interconnects predictably. Read on to understand this important concept.

If we know how to design interconnects that correlate with the measurements for 28 Gbps NRZ, is it going to be a "free lunch" to move to 56 Gbps NRZ? Not so easily, as I learned recently. Read on to see how you can benefit from some analysis and validating your tools.

We are usually not worried about having via stubs on power and ground planes and shapes. Does it mean they are completely harmless?  When it comes to potential damage to high-speed signals, power-via stubs can be almost equally as bad as signal-via stubs.  Here is how and why.

Nyquist frequency, first harmonic, clock frequency, fundamental frequency, and some other intimidating terms might be thrown at you by an SI engineer. Read on to get up to speed on these and other terms you need to know.

When I first started studying Maxwell’s Equations, I was always intrigued by its mathematical finesse. How could someone think of that? Today we take them for granted and we sometimes forget how amazing they are and what a genius the guy was. In my view, James Maxwell should be with, if not above, Einstein and Newton among the greatest physicists to ever live, but outside our field people seldom know who Maxwell was.
