| Outline of Final Research Achievements |
It is difficult for the existing methods for the stuck-at faults and the transition delay faults to guarantee the quality of the high-speed system on chips. In this study, we proposed a concept of 2 pattern-2 pair tests as a high quality diagnostic test for resistive open faults. Also we proposed methods for generating the diagnostic tests by using SAT solver and the Simulated Annealing. We proposed an on-chip sensor that is applied by the analog boundary-scan as a design-for diagnosis. Moreover, we proposed a diagnostic method based on the ranking of the sensitized paths. From the experimental results for the benchmark circuits, we show that the proposed methods can generate the high quality diagnostic tests and the proposed diagnosis method can obtain the better diagnostic resolutions compared with the existing methods.
