ID:23601 Cannot use READ_DURING_WRITE_MODE_MIXED_PORTS parameter value set to OLD_DATA 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 READ_DURING_WRITE_MODE_MIXED_PORTS parameter value set to OLD_DATA 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 READ_DURING_WRITE_MODE_MIXED_PORTS parameter value to DONT_CARE. To avoid receiving this message in the future, Intel recommends using the IP Parameter Editor.
