A logic option that specifies the control block used for calibrated on-chip termination (OCT) Definition and impedance matching for an I/O pin. OCT helps to prevent signal reflections and maintain signal integrity. This option is ignored if it is applied to anything other than an I/O pad, input buffer, or output buffer. This option should only be used on I/O pins which have a calibrated termination assignment.
This option is available for supported device(ArriaII, StratixIII, Stratix IV, and StratixV )families.
