Functional Description
The wide multiplexers can be used by the automatic tools or
instantiated in a design using a component such as the
F5MUX. The symbol, signals, and function are described
below. The description is similar for the F6MUX, F7MUX,
and F8MUX. Each has versions with a general output, local
output, or both.

Carry and Arithmetic Logic
For additional information, refer to the “Using Carry and
Arithmetic Logic” chapter in UG331.
The carry chain, together with various dedicated arithmetic
logic gates, support fast and efficient implementations of
math operations. The carry logic is automatically used for
most arithmetic functions in a design. The gates and multi-
plexers of the carry and arithmetic logic can also be used for
general-purpose logic, including simple wide Boolean func-
tions.
The carry chain enters the slice as CIN and exits as COUT,
controlled by several multiplexers. The carry chain connects
directly from one CLB to the CLB above. The carry chain
can be initialized at any point from the BX (or BY) inputs.
The dedicated arithmetic logic includes the exclusive-OR
gates XORF and XORG (upper and lower portions of the
slice, respectively) as well as the AND gates GAND and
FAND (upper and lower portions, respectively). These gates
work in conjunction with the LUTs to implement efficient
arithmetic functions, including counters and multipliers, typ-
ically at two bits per slice. See
