ID:84030 When PARAM <name> has the specified parameter value, port <name> is not supported

CAUSE: The port you specified for the altmult_add megafunction is illegal when the specific parameter value is used. This error usually occurs when you instantiate a megafunction directly in a text file rather than using the MegaWizard Plug-In Manager .

ACTION: To avoid receiving this message in the future, Intel recommends using the MegaWizard Plug-In Manager.
