Fast OCT Register logic option
A logic option that implements an on-chip termination (OCT) Definition register in a cell that has a fast, direct connection to an I/O pin. Turning on the Fast OCT Register logic option can help maximize I/O timing performance, for example, by permitting fast clock-to-output times. Turning this option off for a particular signal prevents the Fitter from implementing the signal automatically in an I/O cell. This option is ignored if it is applied to anything other than a register or an output or bidirectional pin fed by a register.
This option is available supported device (Arria® II,Stratix® IV, and Stratix® V) families.
