To import I/O port definitions from an XDC file:
  1. Select File > Import > Import I/O Ports.
  2. In the Import I/O Ports dialog box, select XDC File, and browse to select the file to import.

Because the XDC format does not define port direction, the direction is undefined. To define the I/O port direction, right-click in the I/O Ports window, and select Set Direction. You can also directly modify the direction of a specific I/O port in the I/O Ports window. For more information, see Setting I/O Port Direction.
