Timed fault diagnosis

2007 European Control Conference (ECC), 2007
Time has been shown to be determinant in many diagnosis situations. A way to account for time is to enrich the fault signature matrix with time information. However this requires to anticipate the symptoms occurrence order or provide estimates for the symptom occurrence dates.

Delay Fault Diagnosis

1998
Testing fabricated chips for correct temporal behavior is typically done by applying a set of input vector pairs at-speed to the chip under test, and comparing the sampled circuit outputs with their expected logic values. Assuming that the chip is functionally correct, i.e., it produces the correct output values given sufficient time, any discrepancy ...

Analog Fault Diagnosis

1988
A simulation-after-test algorithm for the analog fault diagnosis problem is presented, in which a bound on the maximum number of simultaneous faults is used to minimize the number of test points required. Based on this self-testing algorithm, an analog automatic test program generation (AATPG) for both linear and nonlinear circuits and systems is being

On Undetectable Faults and Fault Diagnosis

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2010
The presence of an undetectable fault ui may modify the response of a detectable fault dj to a test set used for fault diagnosis. This may impact the accuracy of fault diagnosis based on the responses of single faults. Many state-of-the-art diagnosis processes are based on the responses of single stuck-at faults even though their goal is to diagnose ...

Ongoing fault diagnosis

Proceedings 15th Symposium on Reliable Distributed Systems, 2002
We consider a dynamic fault diagnosis problem: there are n processors, to be tested in a series of rounds. In every testing round we use a directed matching to have some processors report on the status (good or faulty) of other processors. Also, in each round up to t processors may break down, and we may direct that up to t processors are repaired.

Fault Diagnosis and Fault Model Aliasing

IEEE Computer Society Annual Symposium on VLSI: New Frontiers in VLSI Design (ISVLSI'05), 2005
During fault diagnosis, the existence of equivalent faults, or faults that are not distinguished by the test set applied to the circuit, can create ambiguity as to the location of a defect. This happens if the circuit-under-test produces a response that matches the circuit response in the presence of two faults in different locations of the circuit ...

Fault Diagnosis Systems

2014
Sensors and real apparatus are prone to faults that, in turn, affect the quality of retrieved data. Detection of faults or erroneous behaviors in sensor data stream must be anticipated to prevent drastic side effects (recall we make decisions out of incoming data).

Automated Fault Diagnosis

1986
Machinery condition monitoring and fault diagnosis using a fault matrix and process deviation approach is described. In particular the application of computer aided diagnosis using an expert system based on artificial intelligence is considered. A prototype fault finding system has been developed and tested. Some examples from this system and some more
