The AMD LogiCORE™ IP UltraScale architecture Soft Error Mitigation (SEM) controller is an automatically configured, pre-verified solution to detect and correct soft errors in the configuration memory of AMD FPGAs. Soft errors are unintended changes to the values stored in state elements caused by ionizing radiation.
The SEM controller does not prevent soft errors; however, it provides a method to better manage the system-level effects of soft errors. Proper management of these events can increase reliability and availability, and reduce system maintenance and downtime costs.
