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.
