3.2.3.3.1. Carry Chain

The carry chain provides a fast carry function between the dedicated adders in the arithmetic mode.

The 2-bit carry select feature in Agilex™ 5 devices splits the propagation delay of carry chains with the ALM. Carry chains can begin in either the first ALM or the sixth ALM in a LAB. The final carry-out signal is routed to an ALM, where it is fed to local, row, or column interconnects.
