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. Since, by the occurrence probability providing part 9, a new diagnosis value is used and, the occurrence probabilities of possible faulty logic combinations are taken into consideration, the reality in a deep-submicron LSI circuit is better reflected, which contributes to the improvement of diagnostic resolution.
