ID:84046 <name> must be 44 or width_a + width_b + 8 in chainout mode with <name> device family

CAUSE: You select the chainout mode in altmult_add megafunction and width_result is not 44 or (width_a + width_b + 8); however, with_result can only be 44 or (width_a + width_b + 8) when chainout mode is turned on. 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.
