Fault Diagnosis of Analog Circuits Based on Adaptive Test and Output Characteristics
Yukiya Miura, Jiro Kato · Proceedings · 2006
A method for diagnosing analog circuits that is realized by combining the operation-region model and the X-Y zoning method have been proposed. In the method, the authors cloud implement a diagnosis procedure based on a diagnostic method for digital circuits. In this paper, the method by using an adaptive test to obtain a shorter diagnostic sequence length was improved and its characteristics were shown. Moreover, a new data processing method that utilizes the output response of a circuit to obtain better diagnostic performance was proposed. The effectiveness of the proposed methods by applying them to ITC'97 benchmark circuits was demonstrated with hard faults and soft faults. These improved methods can reduce a diagnostic sequence length without degrading the performance of diagnostic resolution and CPU time
