A New Built-In Self-Test Design for PLA's with Hligh Fault Coverage and Low Overhead
March 1987 (vol. 36 no. 3)
pp. 369-373
R. Treuer, Department of Electrical Engineering, McGill University
This correspondence presents a new built-in self-test design for PLA's, that has a lower area overhead and higher multiple fault coverage (of three types of faults: crosspoint, stuck, and bridging) than any existing design. This new design uses function independent test input patterns (which are generated on chip), compresses the output responses into a function independent string of parity bits (whose fault-free expected values are generated on-line with a simple circuit), and detects all siqgle faults and more than ( 1 --2(m+2n) of all multiple faults where m and n represent the number of product terms and input variables, respectively.
Index Terms:
VLSI design, Built-in self test (BIST), fault coverage, fault models, output response compression, parity bits, programmable logic array (PLA), test pattern generation
