LL 40-100GbE IP Core Octets Counter Error Following Two Short Back-to-Back Packets

Environment

  • Quartus® II Subscription Edition
  • Ethernet
    • BUILT IN - ARTICLE INTRO SECOND COMPONENT

    Critical Issue

    Description

    If the LL 40-100GbE IP core receives two short packets back to back on the Ethernet link, the IP core might misinterpret the second packet as having an FCS error. In this case, the 64-bit RxOctetsOK counter does not record the bytes from the second packet.

    Resolution

    This issue has no workaround. This issue will be fixed in a future version of the LL 40-100GbE IP core.
