OCT Specifications
If you enable on-chip termination (OCT) calibration, calibration is automatically
performed at power up for I/Os connected to the calibration block.
lists the Arria V OCT termination calibration accuracy specifications. The OCT
calibration accuracy is valid at the time of calibration only.

Calibration accuracy for the calibrated on-chip series termination (R
S
OCT) and
on-chip parallel termination (R
T
OCT) are applicable at the moment of calibration.
When process, voltage, and temperature (PVT) conditions change after calibration,
the tolerance may change.
