To set I/O port direction, use any of the following methods:

  • For I/O planning projects only:
    • In the Direction column of the I/O Ports window, click a port and change the direction using the drop-down menu.
    • Click a port in the I/O Ports window, and change the direction in the I/O Port Properties window.
    • Select the I/O ports, buses, or interfaces to be configured in the I/O Ports window, right-click, and select Set Direction.
  • For RTL projects only, define the port direction in the RTL source.
    Important: You can only set the port direction property in an I/O planning project. If you attempt to modify this property outside of an I/O planning project, a critical warning is issued.
