ABSTRACT:
A programmable logic array (PLA) is tested by applying a sliding-ones pattern to the bit lines from a circular shift register, and individual product lines are selected by applying a sequence of addresses from a linear feedback shift register (LFSR) to an integral decoder. Both the circular shift register and the LFSR are controlled by a common clock signal, avoiding the need for special synchronizing logic between them. The sequence lengths of the circular shift register and the LFSR are chosen to be coprime numbers. Thus, after a predetermined number of clock beats, all the crosspoints in the AND plane will have been individually tested.
