Adaptive Look-Up Table (ALUT) Definition
An Adaptive Look-Up Table (ALUT) is a logical construct that represents what can be implemented by the combinational logic hardware of an Adaptive Logic Module (ALM) in supported device ( Arria® series, Cyclone® V , Stratix® IV, and Stratix® V ) families. When a report refers to ALUT usage, the physical resources represented differ based on device family.
