You can automatically assign I/O ports to package pins in an open synthesized design. The Vivado IDE obeys I/O standard and differential pair rules and places global clock pins appropriately.

To automatically assign I/O ports:

  1. In the I/O Ports window, select the I/O ports to place.
  2. Select Tools > I/O Planning > Auto-place I/O Ports.
    Note: Alternatively, you can right-click, and select Auto-place I/O Ports in the I/O Ports window.
  3. In the Autoplace I/O Ports wizard (see the following figure), select the group of I/O ports to place, and click Next.

  4. If you selected I/O ports that are already assigned to package pins, select an option in the Placed I/O Ports page, and click Next.

  5. In the Summary page, click Finish.
