ID:23615 Cannot use OPERATION_MODE parameter value set to ROM with M-RAM block in altera_syncram megafunction

CAUSE: You specified the RAM_BLOCK_TYPE parameter of the altera_syncram megafunction with the M-RAM value; however, the OPERATION_MODE parameter value set to ROM cannot be used with the M-RAM block. This error usually occurs when you instantiate a megafunction directly in a text file rather than using the IP Parameter Editor .

ACTION: Modify the design and use a different RAM_BLOCK_TYPE parameter value, or set the OPERATION_MODE parameter value to another value. To avoid receiving this message in the future, Intel recommends using the IP Parameter Editor. Use a different RAM_BLOCK_TYPE or change the mode.
