The OCT termination without calibration is not supported by the Stratix® III device family in the military temperature range (-55 to 125C). The default OCT setting for the IO pin is “Series 50 Ohm without calibration”. You will get a fitter error when you set the junction temperature to the military temperature range in the Quartus® II software. Use programmable drive strength or OCT with calibration for the pin to prevent the error.
