Carry Chain Generator
The Carry Chain Generator is useful for implementing high-speed arithmetic functions. The CCG consists of a two-
input XOR gate whose carryout can be cascaded with the input of the adjacent CCG. As shown in Figure 5, the
carryin signal feeds CLE3 of the PFU and is propagated through CLE2 and CLE1 before reaching CLE0. The sum
output of the CCG can be fed to the CSE through the WLG. The carryout must propagate to CLE0 for use outside
the PFU. The carryout from the PFU can feed the W0 input of CSE0. The CCG also helps to effectively implement
wider functions by using its logic elements to expand the capabilities of the LUT-4.

Wide Logic Generator
The WLG contains the logic necessary to implement wide gate functions. This is made up of a set of multiplexers
that are located between the CLE and the CSE. The WLG helps in enhancing the wide gating capability of the PFU.
The outputs of each CLE can be cascaded in the WLG to build wide gating functions. Wide multiplexing functions
are also possible with a similar use of the WLG. Figure 6 illustrates the WLG.
