ID:16475 In altera_syncram megafunction, clock0 port must always be connected

CAUSE: The clock0 port of the altera_syncram megafunction is not connected; however, the clock0 port must always connect because the altera_syncram megafunction is a synchronous RAM megafunction. 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 the clock0 port of the altera_syncram megafunction. To avoid receiving this message in the future, Intel recommends using the IP Parameter Editor.
