Abstract(in English) | There are faults which can be detected by only the invalid test patterns. This is one of the causes for the overtesting. Overtesting occurs that faults on a chip are detected under invalid states using scan chains. However it is difficult to find all invalid states based on circuit structures. On the other hand, untestable faults identification can be used sequential ATPG based on time expansion models. The our proposed method is composed of generating multi cycle capture test patterns, identifying untestable faults and extracting single cycle capture patterns from multi cycle capture sequences to reduce the number of detection for untestable faults. |
