Note that the conguration of the logic allocator has absolutely no impact on the speed of the
signal. All congurations 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 ip-
op 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 rst XOR
input will be a logic 0. This circuit has the exibility 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.
