Why does the eye width measurement display zero in the Eye Viewer of the F-Tile FGT Transceiver Toolkit in the Intel® Quartus® Prime Pro Edition Software version 22.2 when running in internal serial loopback mode?

Environment

  • Intel® Quartus® Prime Pro Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a problem with the firmware in the Intel® Agilex™ F-tile devices with the ordering part number (OPN) ending VR0, VR1 or VR2, the results of “eye width time” and “eye width UI” will return a 0 value when trying to run Eye Viewer to measure eye width in internal serial loopback mode.

    Resolution

    There is no workaround for this problem for devices with OPN ending VR0, VR1 or VR2.
    This problem is fixed in newer Intel Agilex F-Tile devices with OPN ending VR3 or AA.
