Why is there a functional error on M20K blocks in Intel® Agilex™ devices after doing Partial Reconfiguration (PR)?

Environment

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

    Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 22.2 and earlier, you might see a functional error on M20K blocks in Intel® Agilex™ devices after Partial Reconfiguration (PR) if the base design does not use those M20K blocks.

     

    When the problem happens, the failed M20K blocks are stuck, and you will not be able to read or write to them correctly.

    You will not see such a functional error on the M20K blocks already used in the base design.

     

    This problem can be recovered after doing a full chip reconfiguration.  

     

     

    Resolution

    To fix this problem, download and install the following patch according to your Intel® Quartus® Prime Pro Edition Software version, and then regenerate the programming files for both the base image and PR image.

    • Intel® Quartus® Prime Pro Edition Software v22.1 - Patch 0.40fw
    • Intel® Quartus® Prime Pro Edition Software v21.4 - Patch 0.80fw
