ID:84037 When width_result bigger than the mathematical width of result and dynamic sign is used, the mega function will sign extends the mathematical result to match the requested width of result

CAUSE: You specified a width_result greater than the mathematical width of the result in a altmult_add megafunction, and you also used a dynamic sign. The megafunction will sign extend the mathematical result to match the requested width of the result.

ACTION: To avoid receiving this message in the future, use a smaller width_result or do not use a dynamic sign. Or, to avoid receiving this message in the future, Intel recommends using the MegaWizard Plug-In Manager.
