Why doesn't the In-System Memory Content Editor work on hardware in Intel® Stratix® 10 devices.

Description

Due to a problem in the Intel® Quartus® Prime Pro Edition software, you may see that the In-System Memory Content Editor(ISMCE) does not work correctly on hardware. This problem occurs when the memory block type is set to Auto and is then implemented as an MLAB. This problem only affects Intel® Stratix® 10 devices and newer.

Resolution

To work around this problem, always select M20K memory block type.

This problem is fixed beginning with version 20.1 of the Intel® Quartus® Prime Pro Edition software.
