Note that the configuration of the logic allocator has absolutely no impact on the speed of the signal. All
configurations have the same delay. This means that designers do not have to decide between optimizing
resources or speed; both can be optimized.
If not used in the cluster, the extra product term can act in conjunction with the basic cluster to provide
XOR logic for such functions as data comparison, or it can work with the D-,T-type flip-flop to provide
for J-K, and S-R register operation. In addition, if the basic cluster is routed to another macrocell, the extra
product term is still available for logic. In this case, the first XOR input will be a logic 0. This circuit has the
flexibility to route product terms elsewhere without giving up the use of the macrocell.
Product term clusters do not “wrap” around a PAL block. This means that the macrocells at the ends of
the block have fewer product terms available.
