ID:84059 WIDTH_COEF parameter value is illegal

CAUSE: The WIDTH_COEF parameter value is illegal. The legal value is either 18 or 27. 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 the correct parameter value.
