Why does the Low Latency 100-Gbps Ethernet IP Core with CAUI-4 PCS and RS-FEC enabled generate periodic blocks of errors after 2 hours when implemented in the Intel® Arria® 10 GT device?

Description

Due to a problem in the Intel® Quartus® Prime software versions 19.3 and earlier, the Low Latency 100-Gbps Ethernet IP Core with CAUI-4 PCS and RS-FEC enabled will generate periodic bursts of errors over time when implemented in the Intel® Arria® 10 GT device.

Resolution

To work around this issue, re-generate the IP core in the Intel® Quartus® Prime software 19.4 or later.
