what pin to assign to node named "rzqin" in DDR3 interfacing using hard memory controller design targeted for cyclone V GT (5CGTFD9E5F35C7) development board?

No pin is name is given for this node(ZQ impedance calibration) in board reference manual, there is a dash against it as can be seen in below image,

According to the board schematic on sheet 4 (https://www.intel.com/content/www/us/en/programmable/products/boards_and_kits/dev-kits/altera/kit-cy...), it's AP19, but you don't need to make an assignment to it because it's hardened and connected to the RZQ resistor.
