In any programmable logic array (PLA) where it is possible with proper assignment of ""don't care'' crosspoints to cause a PLA output to always produce a logical ""1'' or always product a logical ""0'' response regardless of what input combination is applied to the PLA, the OR array column used to produce that output is deleted and replaced by a simple tie-up or tie-down circuit at the output. The use of this technique reduces the size of the OR array in the PLA.
