ID:84033 DSP block is using rounding, but the parameter WIDTH_MSB is out of the range. The range of the WIDTH_MSB is decided by the input data width, result width and the operation mode.

CAUSE: A hardware rounding circuit is being used with the altmult_add megafunction, and the value of the rounding width is between 22 and 37. 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.
