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 1-8: OCT Calibration Accuracy Specifications for Arria V Devices
Calibration 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 afer calibration, the tolerance may change.
