You can manually modify memory I/O ports, such as swap pins, using the I/O
Ports window or the Package Pins window. Both windows are expandable data tables, which
you can manipulate to more easily view information. For example, you can expand or
collapse the table, filter lists, or sort and move columns. For more information, see
section "Using Data table Window" in the
Vivado
Design Suite User Guide: Using the Vivado IDE (UG893).
Important: DRCs are not performed as you make changes, which
means it is possible to make invalid pin assignments for the memory controller.
After you modify the I/O ports or package pin assignments, it is important to run
DRCs as described in Running DRCs.
