ID:176178 Input pin <name> must use differential I/O standard when using differential path connections -- automatically assigned <name> differential I/O standard to pin

CAUSE: You assigned a non-differential I/O standard to the specified input pin that has a differential path connection. However, pins with differential path connections can use only a differential I/O standard. The Fitter automatically assigned the specified differential I/O standard to the input pin.

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