ID:84057 Can't select more than three clock and clock enable pairs in the <name> device family

CAUSE: You selected more than three clock and clock enable pairs for the specified device family, but this feature is not supported. 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 to regenerate the altmult_add megafunction with supported features for the specified device family.
