CAUSE: The Fitter is reporting that your design contains one or more non clock differential I/O pins that do not connect to a SERDES receiver or transmitter. Non clock differential I/O pins that are not connected to a SERDES receiver or transmitter have less stringent placement restrictions than non clock differential I/O pins that are connected to a SERDES receiver or transmitter. If you modify your design to connect the non clock differential I/O pins to the SERDES receiver or transmitter, the Fitter may not be able to fit your design in the device.
ACTION: If you do not want to connect non clock differential I/O pins to a SERDES receiver or transmitter, no action is required. Otherwise, modify your design to ensure that the non clock differential I/O pins are connected to a SERDES receiver or transmitter.
