ID:95020 Cannot use OPERATION_MODE set to value BIDIR_DUAL_PORT with <ram_block> block in altsyncram megafunction
CAUSE: You specified the OPERATION_MODE parameter of the altsyncram megafunction with the BIDIR_DUAL_PORT value; however, the OPERATION_MODE parameter set to value BIDIR_DUAL_PORT cannot be used with the M512 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 change the memory block type, or change the value of the OPERATION_MODE. To avoid receiving this message in the future, Intel recommends using the MegaWizard Plug-In Manager.
