MIG Spartan-6 MCB - Simultaneously Switching Noise (SSN) Calculation


What is the appropriate MIG flow for analyzing simultaneously switching outputs/noise?

Note:This Answer Record is part of the Xilinx MIG Solution Center (Xilinx Answer 34243). The Xilinx MIG Solution Center is available to address all questions related to MIG. Whether you are starting a new design with MIG or troubleshooting a problem, use the MIG Solution Center to guide you to the right information.


Hardware characterization of MCB-based memory interfaces indicates that there are no Simultaneous Switching Output (SSO) related restrictions when using the predefined IOB locations up to their maximum extent (that is, the maximum number of data and address pins in the interface). For more information, please seethe "Simultaneous Switching Output Considerations" sections in the Spartan-6 FPGA Memory Controller User Guide(UG388).
