Analyze simultaneous switching noise in PCBs
Author:Geing Liu, Hong Shi, Alan Chang, San Wong

This article from Altera offers a systematic SSN overview with the focus on SSN caused by FPGA output buffers. A description of the causes of system-level SSO is presented and a hierarchical system-level SSO modeling methodology is proposed. A procedure for correlating the SSO models to frequency- and time-domain measurements is provided and several PCB design methodologies for minimizing SSO in PCBs are offered.
