Why do some of the TX statistics of the 40/100G Ethernet MAC always read '0'?

Environment

  • Intel® Quartus® Prime Pro Edition
  • Low Latency 40G 100G Ethernet
  • Low Latency 40G Ethernet Intel® FPGA IP for Arria® 10 and Stratix® V
  • Low Latency 100G Ethernet Intel® FPGA IP for Arria® 10 and Stratix® V
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a problem in the Quartus® Prime software, the following TX statistics registers will read back as '0': CNTR_TX_FRAGMENTS_LO, CNTR_TX_JABBER_LO, CNTR_TX_CRCERR_LO, CNTR_TX_FRAGMENTS_HI, CNTR_TX_JABBER_HI, CNTR_TX_CRCERR_HI

    Resolution

    This problem is not scheduled to be fixed. To work around this issue, the user should create his own counters for these statistics.
