Description
If the hard PRBS checker is enabled via the reconfiguration interface of the Intel® Arria® 10 Low Latency 40-GbE IP core, it will fail due to PCS logic always asserting rx_digitalreset.
Resolution
To use the hard PRBS checker, enable ADME (Altera® Debug Master Endpoint) and use Transceiver Tool Kit (TTK) to enable the PRBS checking.
