The I/O Ports window (shown in the following figure) enables you to create, configure, and place I/O ports onto I/O sites in either the Package window or Device window. The I/O Ports window shows the I/O signal ports defined in the design. To open the I/O Ports window, select Window > I/O Ports.

Creating RTL source or netlist projects populates the I/O Ports window with the I/O ports defined in the design source files. In an I/O Planning project, you can import a port list from a CSV or XDC file and create ports manually for the project. For more information, see the Vivado Design Suite User Guide: I/O and Clock Planning (UG899).

    Note: For more information on using the platform board flow, see the Vivado Design Suite User Guide: System-Level Design Entry (UG895).
  • Package pin
  • I/O bank

The table in the I/O Ports window includes the following information:

  • Port Interfaces are in expandable folders that can contain buses and individual ports that you defined.
  • Cells with editable values allow you to enter text or select text from drop-down menus.

Table values appear as follows:

  • Blank for default values
  • An asterisk (*) for non-default values
  • Red for illegal or undefined values
