As Dave Dunham from Molex Corp. likes to say “When designing high speed serial links beyond 10 GB/s, everything matters“. Part of that everything is accurate modeling of transmission line losses. It is important to model dielectric and conductor loss accurately.
Here is a very useful presentation with speaker notes on the topic of “Practical Modeling of High Speed Channels Based on Datasheet Input” presented by Bert Simonovich, Lamsim Enterprise Inc at EDICON 2017.
Here is the motivation of the methodology proposed:
As my friend Eric Bogatin often likes to say, “Sometimes an OK answer NOW! is better than a good answer late.” As a high-speed signal integrity practitioner and backplane architect, I often have to come up with an answer sooner, rather than later because of the impact to time and cost to my clients. And that’s why I have been motivated over the last few years to research and develop a simple methodology to accurately determine parameters to feed into modern EDA tools .
