ID:16484 Must connect <name> port of altera_syncram megafunction when using current set of parameters

CAUSE: You did not specify the specified port of the altera_syncram megafunction; however, when you use the current set of parameters, the specified port must be connected. 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 connect specified port of the altera_syncram megafunction, or change the parameters so that they do not require the specified port. To avoid receiving this message in the future, Intel recommends using the IP Parameter Editor.
