ID:68004 WIDTH_MAN parameter of the altfp_inv_sqrt megafunction has value <number> -- however, the WIDTH_MAN parameter value must be 23 and the WIDTH_EXP parameter value must be 8 for single precision floating point format

CAUSE: You specified a value for the WIDTH_MAN parameter of the altfp_inv_sqrt megafunction. When the WIDTH_MAN parameter has the specified value, the altfp_inv_sqrt megafunction assumes that you want single precision floating point format. The WIDTH_MAN parameter must be set to 23 and the WIDTH_EXP parameter must be set to 8 for single precision floating point format. This error usually occurs when you instantiate a megafunction directly in a design file rather than using the MegaWizard Plug-In Manager .

ACTION: Change the value of the WIDTH_MAN parameter to 23 and the value of the WIDTH_EXP parameter to 8 of the altfp_inv_sqrt megafunction for single precision floating point format.
