Why is M20K dual-port RAM data corrupted in the first read operation or the first write operation when using rd_addressstall or wr_addressstall in the Intel® Stratix® 10 device?

Environment

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

    Due to a problem of the Intel® Quartus® Prime Pro software version 18.1.1 and later, M20K dual-port RAM data may be corrupted in the first read operation or the first write operation when using rd_addressstall or wr_addressstall in the Intel Stratix® 10 device.  This problem is observed only when rd_addressstall or wr_addressstall is initially high from the beginning of user mode and is kept high until the 1st read operation or the 1st write operation.

    Resolution

    This problem has been fixed since the Intel Quartus Prime Pro software version 20.3.
