Preamble Pass Through Mode in 10-Gbps Ethernet MAC Does Not Meet Average IPG

Environment

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

    Critical Issue

    Description

    10GbE MAC designs with the Enable preamble pass-through mode option turned on, the average inter-packet gap (IPG) is set to 16 instead of 12. Your designs will have lower throughput.

    This issue will be fixed in a future version of the 10GbE MAC MegaCore function.
