Why does the MegaWizard Plug-in Manager generate an ALTDDIO_IN or ALTDDIO_OUT megafunction with a width of 8 when different custom width is specified?

Description

Due to a problem in the MegaWizard™ Plug-in Manager, ALTDDIO_IN or ALTDDIO_OUT megafunctions may be generated with a width of 8 even though a different custom width is specified in the Width field.

Resolution

To work around the issue, after manually typing in the width value in the Megawizard Plug-In Manager, press the Enter key. The MegaWizard Plug-In Manager refreshes the diagram with the correct width value. After clicking the Finish button, the MegaWizard Plug-In Manager generates the variation file with the correct custom width.
