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?

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.

Workaround/Fix

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