A method is presented to design pseudoexhaustive testable (PET) PLAs (programmable logic arrays) that are suitable for BIST (built-in self-test) environments. The key idea of the design is to partition inputs and product lines into groups. During testing, a group of inputs and a group of product lines are selected and tested exhaustively. The proposed design leads to small test sizes and relatively small area overhead. Experimental results on 30 PLAs, comparing test set sizes and area overhead of different BIST PLA designs, are reported
