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:
- In the I/O Ports window, select the I/O ports to place.
- Select .Note: Alternatively, you can right-click, and select Auto-place I/O Ports in the I/O Ports window.
- In the Autoplace I/O Ports wizard (see the following figure), select the
group of I/O ports to place, and click Next.
- 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.
- In the Summary page, click Finish.
