Abstract: In a programmable logic device having a plurality of gates capable of being programmed according to a plurality of product terms representing logic functions, an apparatus for allocating the product terms to a plurality of outputs. A first set of product terms are steerable to one of at least two outputs. A second set of product terms is permanently assigned to a predetermined output. The second set is comprised of more product terms than the first set, wherein the average number of product terms per output is low, yet a user has the flexibility of implementing logic functions requiring a relatively large number of product terms.
