Spartan-IIE FPGA Family: Functional Description
Additional Logic
The F5 multiplexer in each slice combines the function gen-
erator outputs
a function generator that can implement any 5-input func-
tion, a 4:1 multiplexer, or selected functions of up to nine
inputs.

Similarly, the F6 multiplexer combines the outputs of all four
function generators in the CLB by selecting one of the two
F5-multiplexer outputs. This permits the implementation of
any 6-input function, an 8:1 multiplexer, or selected func-
tions of up to 19 inputs.
