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. This 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
an LAB. The Quartus II Compiler creates shared arithmetic chains longer
than 16 (8 ALMs in arithmetic or shared arithmetic mode) by linking
LABs together automatically. For enhanced fitting, a long shared
