Shared Arithmetic Chain
In addition to the dedicated carry chain routing, the shared arithmetic
chain available in shared arithmetic mode allows the ALM to implement
a three-input add, which significantly reduces the resources necessary to
implement large adder trees or correlator functions. The shared
arithmetic chains can begin in either the first or fifth ALM in a LAB. The
Quartus II Compiler automatically links LABs to create shared arithmetic
chains longer than 16 (8 ALMs in arithmetic or shared arithmetic mode).
For enhanced fitting, a long shared arithmetic chain runs vertically
