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

Environment

  • Intel® Arria® 10 GT FPGA
  • Low Latency 40G Ethernet Intel® FPGA IP for Arria® 10 and Stratix® V
  • Low Latency 40G 100G Ethernet
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    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.
