Termination Control Block logic option

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 (Arria^® II, Stratix^®III, Stratix^® IV, and Stratix^®V )families.
