ID:84051 <name> should be 8 + width_a + width_b to support port <name> in <name> device family

CAUSE: You select the specific value of the specific parameter in altmult_add megafunction; however, this value of the specific parameter is not supported in this device family for the specific port. 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.
