You may encounter the following failure when using Single Event Upset (SEU) feature in Intel® Quartus® Prime Pro software version 18.1:
1. After performing Partial Reconfiguration (PR), the SEU error detection on the PR region will not function as expected.
2. If SEU error detection happened in both priority and non-priority region (when you enable Priority Scrubbing), the first SEU error message read out from the queue is the error from non-priority region.
