  • Patent number: 7913144
    Abstract: Provided are a diagnostic device and the like providing a favorable diagnosis result by further improving the diagnosis resolution. A diagnostic device 1 has a symbol injection part 3, which is composed of a symbol injection part for an active element 5 and a symbol injection part for a passive element 7, an occurrence probability providing part 9, an equal occurrence probability providing part 11, and a switching part 13. A per-test X-fault diagnosis flow by the diagnostic device 1 consists of a stage for collecting diagnostic information and a stage for drawing diagnostic conclusion. The layout of a deep-submicron LSI circuit usually needs to involve multiple layers, which means that vias are extensively used. Since via information is utilized by the symbol injection part for a passive element 7, it becomes possible to locate defects to the via level, greatly improving the diagnostic resolution.

  • Patent number: 7437340
    Abstract: The area of the circuit to be added for easy testability is reduced. Operations contained in a behavioral description are extracted in an operation analyzing unit; when expanding any operation at the time of behavioral synthesis, if the area of the circuit can be reduced to a greater extent when a DFT is applied to the operation before expansion, a parameter indicating that the operation is not to be expanded at the time of behavioral synthesis is generated and DFT information is added to a DFT library. A behavioral synthesis unit, in accordance with the parameter, generates an RTL description without expanding the operation. A DFT unit implements the DFT by referring to the DFT library, and thereafter expands the operation.

  • Publication number: 20030188239
    Abstract: In a strongly testable DFT method, the length of a test sequence is reduced, thereby reducing the amount of circuitry to be added for testing purposes. Test plans, generated one for each of circuit elements forming a data path, are scheduled in parallel in a form that can be compacted, and a compaction operation is applied to generate a compacted test plan. The test sequence is generated by inserting the test patterns needed for each circuit element into the compacted test plan.
