Values: Use this attribute to set the compatible threshold level for inputs and outputs. The values you can choose from depend on which device you selected.
Default value: The default I/O threshold displayed is based upon the I/O standard. If you want to set the I/O threshold independently of the I/O specification, you must select CUSTOM in the I/O standard cell.
