5.9. On-Chip I/O Termination in Arria V Devices

Dynamic RS and RT OCT provides I/O impedance matching and termination capabilities. OCT maintains signal quality, saves board space, and reduces external component costs.

The Arria® V devices support OCT in all FPGA I/O banks. For the HPS I/Os, the column I/Os do not support OCT with calibration.
