ID:16480 Parameter error: parameter <name> of altera_syncram megafunction set to value <value> is illegal -- legal values for parameter <name> are <choices>

CAUSE: You specified an illegal value for the specified parameter of the altera_syncram megafunction. The specified parameter value must be one of the specified legal values. 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 specify one of the specified legal parameter values. To avoid receiving this message in the future, Altera recommends using the IP Parameter Editor.
