OCT Calibration Accuracy Specifications

If you enable on-chip termination (OCT) calibration, calibration is automatically performed at power up for I/Os connected to the calibration block.

Table 9.  OCT Calibration Accuracy Specifications for Intel® Arria® 10 DevicesCalibration accuracy for the calibrated on-chip series termination (RS OCT) and on-chip parallel termination (RT OCT) are applicable at the moment of calibration. When process, voltage, and temperature (PVT) conditions change after calibration, the tolerance may change.
