ID:176186 Pin <name> must use pseudo-differential I/O standard -- the Fitter will automatically assign <name> pseudo-differential I/O standard to pin

CAUSE: You assigned a non-pseudo-differential I/O standard to the specified pin. However, the specified pin can use only a pseudo-differential I/O standard. The Fitter will automatically assign the specified pseudo-differential I/O standard to the pin.

ACTION: No action is required. To avoid receiving this message in the future, replace the pin assignment I/O standard with a pseudo-differential I/O standard.
