ID:71015 Can't determine the mode based on the I/O ports declaration

CAUSE: The Quartus Prime software cannot determine whether the altfp_matrix_mult megafunction is being used as complex or normal mode based on the I/O ports declaration.

ACTION: Recheck the ports declaration. Make sure that you use only complex I/O ports if want to set the altfp_matrix_mult megafunction in complex mode, and normal I/O ports if want to set the altfp_matrix_mult megafunction in normal mode.
