An integrated framework for diagnosing process faults with incomplete features

Diagnosis with Incomplete Models: Diagnosing Hidden Interaction Faults

This paper extends model-based diagnosis (MBD) (de Kleer and Williams 1987; Reiter 1987) to systems with hidden interaction faults. An interaction fault is present if an interaction among a set of components leads to an observable failure, even though each individual component individually meets the specifications. A naive approach to address interaction faults is to simply account for all poss...

A Design- for-Diagnosis Technique for Diagnosing Integrated Circuit Faults with Faulty Scan Chains

1 This paper is supported in part by National Natural Science Foundation of China (NSFC) under grant No.(60633060), and in part by National Basic Research Program of China (973) under grant No.(2005CB321604). Abstract Scan chains take as much as 30% of the silicon area [1], while scan chain failure accounts for almost 50% of chip failure [2]. Conventional logic diagnosis techniques abort the di...

Techniques for Diagnosing Software Faults

Diagnosing Multiple Faults

Diagnostic tasks require determining the differences between a model of an artifact and the artifact itself. The differences between the manifested behavior of the artifact and the predicted behavior of the model guide the search for the differences between the artifact and its model. The diagnostic procedure presented in this paper is model-based, inferring the behavior of the composite device...

Detecting and Diagnosing Faults

Thema The world is full of faults! Some devices develop faults once they are put into use; some devices have faults from the moment of manufacture. Some faults lead to the unusability of a device or even to catastrophes [6]; some faults can be ignored or are actually never discovered. There is, therefore, an increasing demand for mechanisms that automatically detect, isolate and understand faul...
