Majhi, Ananta K and James, Jacob and Patnaik, Lalit M and Agrawal, Vishwani D (1995) An Efficient Automatic Test Generation System for Path Delay Faults in Combinational Circuits. In: 8th International Conference on VLSI Design, 4-7 January 1995, New Delhi, India, pp. 161-165.
The new test pattern generation system for path delay faults in combinational logic circuits considers robust and nonrobust tests, simultaneously. Once a robust test is obtained for a path with a given transition, another test for the same path with the opposite transition is immediately derived with a small extra effort. To facilitate the simultaneous consideration of robust and nonrobust tests, we derive a new nine-value logic system. An efficient multiple backtrace procedure satisfies test generation objectives. We also use a path selection method which covers all lines in the logic circuit by the longest and the shortest possible paths through them. A fault simulator in the system gives information on robust and nonrobust detection of faults either from a given target set or all path faults. Experimental results on ISCAS ' 85 and ISCAS ' 89 benchmark circuits substantiate the efficiency of our algorithm in comparison to other published results.
