ID:67001 In the altfp_inv megafunction, the value of the WIDTH_EXP parameter is <number>, but the value of the WIDTH_EXP parameter must be at least 8

CAUSE: You specified a value for the WIDTH_EXP parameter of the altfp_inv megafunction. However, the value of the WIDTH_EXP parameter must be at least 8. 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_EXP parameter so that the value of the parameter is greater than or equal to 8.
