| Abstract(in English) | As cellar phones and wireless LANs are popularly used in our lives, mixed-signal LSIs, which have analog circuits for radio-frequency signal processing insides, increased in number, and their fault diagnosis is becoming more and more essential. Previously, we proposed an improved parameter-estimation method for diagnosing parametric faults of analog circuits, and demonstrated that the proposed method makes it possible to diagnose them without any design knowledge. To implement such methods into a diagnostic system, it is necessary to establish efficient algorithms for acquiring parameter solutions to circuit equations. In this paper, we propose algorithms of demonstrating existence of solutions to circuit equations and finding all their solutions. Existence of solutions is shown by excluding non-solution regions in successive binary division, and Newton method and genetic algorithm are introduced to find all the solutions of equations. As a result of evaluating these introduced methods, it was demonstrated to acquire solutions stably and efficiently. |
