Just would like to confirm, you would like to understand if the SEU is happening on critical bit or not right? If yes, then I would recommend you to implement Advanced SEU features (https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug_altadvseu.pdf) to confirm if the failure is critical or not.

When CRC_ERROR happen then it is always a real SEU happening as the configuration will always performed check on the CRAM bit.
