ID:16256 Strictly preserved region mask verification failed for <name> bits. The mask does not match reference mask generated in the design creation compilation. <name>

CAUSE: You attempted to compile a design that contains a strictly preserved region in design modification mode. The specified strictly preserved region mask does not match the reference strictly preserved region mask in the location specified in Quartus Prime INI file.

ACTION: Confirm that indicated region is a subject of design modification compilation by checking the Quartus Prime Fitter report. Ensure that the strict preservation location specified in the Quartus Prime INI file contains a valid reference region mask for the strictly preserved region. The reference mask should be generated in the latest design creation compilation for the region using the same Quartus Prime revision. If the error is still reported, contact Intel for assistance.
