Methods for calculation of eye diagrams for digital links with multiple aggressors having unknown time offsets

摘要

Eye diagrams are often used for the evaluation of the signal quality of high-speed links in digital systems. This article deals with the question of how to efficiently simulate eye diagrams of links that suffer from multiple aggressors. Specifically, two different methods, a deterministic and a statistical simulation approach, for the inclusion of aggressors with unknown time offsets are compared. Their benefits and drawbacks are highlighted and shown for a specific example using measured data from a backplane to daughter card link.
