3.8.1. Simultaneous Switching Noise Analysis

Simultaneous switching noise (SSN) is a noise voltage inducted onto a victim I/O pin of a device due to the switching behavior of other aggressor I/O pins in the device.

Intel provides tools for SSN analysis and estimation, including SSN characterization reports, an Early SSN Estimator (ESE) spreadsheet tool, and the SSN Analyzer in the Intel® Quartus® Prime software. SSN often leads to the degradation of signal integrity by causing signal distortion, thereby reducing the noise margin of a system. You must address SSN with estimation early in your system design, to minimize later board design changes. When your design is complete, verify your board design by performing a complete SSN analysis of your FPGA in the Intel® Quartus® Prime software.
