ID:95022 Cannot use rden_b port with M-RAM block in altsyncram megafunction

CAUSE: You specified the RAM_BLOCK_TYPE parameter of the altsyncram megafunction with the M-RAM value; however, the rden_b port 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 MegaWizard Plug-In Manager .

ACTION: Modify the design and use a different RAM_BLOCK_TYPE parameter value, or do not use the rden_b port. To avoid receiving this message in the future, Intel recommends using the MegaWizard Plug-In Manager.
