This tab, shown in the following figure, only appears if a supported board has been pre-selected as the project part.
In the Associate IP Interface table, only those interfaces appear that are supported by the selected board. When Generate Board Based IO Constraints is selected, the appropriate Board Interface field becomes active. Custom is the default option, allowing customization of the FPGA pinout. The other options allow selection of the supported board physical interfaces, and if selected, then the correct pinout is assigned automatically. By default, the Generate Board Based IO Constraints setting is not enabled.
