Why does the Intel® Stratix® 10 EMIF Toolkit report DQS Enable Calibration failure?

Environment

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

    Critical Issue

    Description

    Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 19.3 and earlier, the Intel Stratix® EMIF Toolkit calibration report may show a DQS Enable Calibration failure even though both the DQ/DQS read and write margins show passing valid window values.

    This DQS Enable Calibration failure report can be ignored if the DQ/DQS read and write margins show passing valid window values.

    Resolution

    To work around this problem in the Intel® Quartus® Prime Pro Edition Software version 19.3 and earlier, you can also verify that the local_cal_success signal is asserted using the Signal Tap Logic Analyzer tool.

    This problem is fixed in the Intel Quartus Prime Pro Edition Software version 19.4 and later.
