Why do PRBS checks fail on the Intel® Arria® 10 Low Latency 40-GbE IP through reconfiguration interface?

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.
