Due to a problem in the Quartus® Prime Pro Edition Software version 24.1 and earlier, you might see that your .qprs file is not taken into account when reopening the External Memory Interface (EMIF) IP after copying your project to a new location or using the Quartus® archiver.
This problem is caused by the use of an absolute path within the External Memory Interface (EMIF) IP .ip file.
To correctly read in the .qprs file, browse to the new location of the .qprs file from within the Platform Designer.
This problem is scheduled to be fixed in a future release of the Quartus® Prime Pro Edition Software.
