Why do the EMIF Efficiency Monitor counters “No readdatavalid Count” and “Master Write Idle Count” continue to incorrectly increment after traffic has completed?

Environment

  • Intel® Quartus® Prime Pro Edition
  • External Memory Interfaces Intel® Stratix® 10 FPGA IP
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a problem in the Intel® Quartus® Prime Pro Edition software version 20.4 and earlier, you may see the EMIF Efficiency Monitor counters “No readdatavalid Count” and “Master Write Idle Count” continue to incorrectly increment after the Traffic Generator 1.0 (TG1) has completed sending traffic and subsequently resetting the Efficiency Monitor status registers by clicking on the Clear Status Registers button.

    Resolution

    This problem is fixed starting with the Intel® Quartus® Prime Pro Edition software version 21.1.
