5.7. FIFO ECC Protection
In the Quartus II software version 13.1 and later, the Serial Lite III Streaming IP core can be protected from Single-Event Upset (SEU) changes using error correcting code (ECC) protection. You can enable this feature using the ECC protection option in the parameter editor. The ECC protection provides additional error status bits that tell you if the ECC was able to perform a correction from the SEU change or if an uncorrectable error has occurred.
