carry multiplexer (MUXCY) can also be used to cascade function generators for
implementing wide logic functions.

X-Ref Target - Figure 5-24
The carry chains carry lookahead logic along with the function generators. There are ten
independent inputs (S inputs – S0 to S3, DI inputs – DI1 to DI4, CYINIT and CIN) and eight
independent outputs (O outputs – O0 to O3, and CO outputs – CO0 to CO3).
The S inputs are used for the “propagate” signals of the carry lookahead logic. The
“propagate” signals are sourced from the O6 output of a function generator. The DI inputs
are used for the “generate” signals of the carry lookahead logic. The “generate” signals are
sourced from either the O5 output of a function generator or the BYPASS input (AX, BX,
CX, or DX) of a slice. The former input is used to create a multiplier, while the latter is used
