For some time, I have followed the work of Dr. Douglas Brooks, who was the head honcho at UltraCAD Design Inc., a PCB design house that specialized in ultra-high-speed designs. Dr. Brooks is the author of a number of books on high-speed design, as well as the developer of calculators and simulators that help predict circuit behavior under various conditions. He has retired, dissolved his company and re-licensed his calculators to “free for download”—they were previously for sale.
His work is interesting, if occasionally-heavy, stuff that can shed light on PCB design issues that may crop up even at the comparatively-slow speeds at which we run our designs. If nothing else, some of the theory illustrated by the simulations is edifying, such as the effects of harmonic loss in idealized square-wave signals.
Take a look when convenient.
