Concurrent Analysis of Signal-Power Integrity and EMC for High-Speed Signaling Systems

Abstract

A robust co-analysis approach for signal integrity, power integrity, and electromagnetic compatibility is successfully established and demonstrated through the investigation of several signal referencing configurations in Double Data Rate (DDR) memory systems. The characterization of power noise coupling into signal channels for two configurations is presented. In addition, a new metric that quantifies the entire signaling system combining simultaneous switching noise and crosstalk is detailed. Finally, the radiated emissions from the power planes in the signalling system are reduced through the proper placement of decoupling capacitors.
