This document provides an agenda for a presentation on signal integrity that includes: defining signal integrity and why it is important; methods for signal integrity analysis including analytical, measurement, and simulation; modeling transmission lines and reflections; analyzing power planes and power integrity; and characteristics needed for successful signal and power integrity analysis and system design. Examples are provided throughout to illustrate key concepts.
