A Systematic Approach for Diagnosing Multiple Delay Faults
نویسندگان
چکیده
In the presence of multiple delay faults, automated diagnostic procedures that make a single fault assumption may give an incorrect diagnosis. In this paper, a systematic approach is proposed for delay fault diagnosis under a multiple fault assumption. Information from the failing test vectors are used to construct a list of single and multiple fault suspects that may have caused all of the observed faulty response. The list of suspects is then pruned and ranked in a novel way by using information from the passing test vectors combined with static timing information.

Diagnosing Delay Faults in Combinational Circuits under the Ambiguous Delay Model
In our previous paper [9] we presented a pathtracing method of multiple gate delay fault diagnosis in combinational circuits. In this paper, we propose an improved method that uses the ambiguous delay model. This delay model makes provision for parameter variations in the manufacturing process of ICs. For the effectiveness of the current method, we propose a timed 8-valued simulation and some n...

A novel algorithm based on Genetic approach for diagnosing Bridging faults, Transitional Delay faults and stuck at faults in LSI circuits is presented. The method of devising a universal set for detecting Bridging faults in testable circuits is investigated. We outline a method that utilizes the information from the stuck-at fault model to accurately diagnose the bridging faults that affect two...
متن کاملMulti-fault Diagnosis in Dynamic Systems
In this paper, we address the problem of diagnosing multiple faults in dynamically changing systems. Currently used popular techniques such as codebook and active probing suffer from limitations imposed by their ”static”, non-temporal nature, and single-fault assumptions. We propose a very simple, linear-time multifault scheme, capable of tracking system changes and diagnosing multiple faults m...

Abstract General faults in regular electrical railways system could be detect by implementing the specific protection functions such as ground fault or sensitive earth fault. Otherwise, in ungrounded electrical railway systems which using both feeding and return contact rail at the same time, fault detection cannot done with above-mentioned function. Due to recent growth in electrical railway ...
متن کاملAn Efficient and Effective Methodology on the Multiple Fault Diagnosis
In this paper, we analyze failing circuits and propose a multiple-fault diagnosis approach. Our methodology has been validated experimentally and has proved to be highly efficient and effective in diagnosing multiple faults. We do not consider the multiple-fault behavior explicitly, but rather use an incremental simulation-based approach to diagnose failures one at a time. Furthermore, to impro...
