Chapter 3. Simultaneous Switching Noise

3.1. Introduction

The inclusion of signal integrity (SI) aspects in an early stage of the design flow is essential for the successful design of high-speed digital devices. Various SI problems may arise during the transmission of signals between integrated circuits (ICs) through the input/output (I/O) lines, causing malfunctioning of the device. Using proper models, these problems can be identified and eliminated so that costly tests, measurements, and redesigns can be avoided.

Noise generated in the power delivery network (PDN) due to I/O switching is often referred to as simultaneous switching noise (SSN). Since the I/Os are driver or receiver circuits connected to interconnections in the package and board, ...
