TL;DR: This model of bridging faults suggests that decreasing the power supply voltage is a promising technique to maximize the real fault coverage of voltage tests, thereby minimizing the number of relatively slow Iddq tests required to achieve high quality.
Abstract: Bridging faults in CMOS circuits sometimes degrade the output voltage and time performance without altering the logic function. The traditional voltage testing models based on the normal power supply voltage do not accurately model this behavior. In this paper we develop a model of bridging faults that accounts for both the bridging resistance distribution and gate sensitization and propagation choices. This model shows that fault coverage increases at lower power supply voltages. It suggests that decreasing the power supply voltage is a promising technique to maximize the real fault coverage of voltage tests, thereby minimizing the number of relatively slow Iddq tests required to achieve high quality.

TL;DR: The study of bridging faults (or short circuits that occur between conducting paths) has become increasingly important with the advent of LSI technology, but what has yet to be explored are the effects of undetectable bridges faults on the tests designed to detect stuck-at faults.
Abstract: The study of bridging faults (or short circuits that occur between conducting paths) has become increasingly important with the advent of LSI technology To date, only a very few papers have been published on this topic Specifically, little is known regarding undetectable bridging faults More importantly, what has yet to be explored are the effects of undetectable bridging faults on the tests designed to detect stuck-at faults

TL;DR: In this article, a fault location technique for power distribution systems considering distributed generation (DG) and uncertainties associated to the fault resistance, load magnitude and model, fault type and faulted node is presented.
Abstract: A proposal of a fault location technique for power distribution systems considering distributed generation (DG) and uncertainties associated to the fault resistance, load magnitude and model, fault type and faulted node is presented in this study. The approach presented here uses only single end measurements at the main power substation and at the DG source. To demonstrate the good performance of the proposed approach, tests on the 24.9 kV IEEE 34 nodes test feeder, which includes three-phase and single-phase laterals, are performed. According to the results, a high performance is obtained in the fault distance estimation, considering the shunt faults and the uncertainties in the proposed test scenarios. Finally, it is demonstrated that the proposed approach helps to maintain high continuity indexes by speeding up the fault location task in modern power distribution utilities.

TL;DR: In this article, a neural-fuzzy network is used to model the dynamics of the power transmission system in fault-free conditions, which is compared to measurements from the power system and the obtained residuals undergo statistical processing according to a fault detection and isolation algorithm.
Abstract: This study proposes neural modelling and fault diagnosis methods for the early detection of cascading events in electric power systems. A neural-fuzzy network is used to model the dynamics of the power transmission system in fault-free conditions. The output of the neural-fuzzy network is compared to measurements from the power system and the obtained residuals undergo statistical processing according to a fault detection and isolation algorithm. If a fault threshold, defined by the fault detection and isolation (FDI) algorithm, is exceeded then deviation from normal operation can be detected at its early stages and an alarm can be launched. In several cases fault isolation can be also performed, that is the sources of fault in the power transmission system can be also identified. The performance of the proposed methodology is tested through simulation experiments.
