This paper presents a novel approach to interconnect fault location for FPGAs during power-on sequence. The method is based on a concept known as fault grading which utilizes defect knowledge during manufacturing test to classify faulty devices into different defect groups. A Built-In Self-Test (BIST) method that can efficiently identify the exact location of the interconnect fault is introduce...

In this paper, methods of fault location are discussed in electrical traction single-end direct power supply network systems. Based on the distributed parameter model of the system, the position of the short-circuit fault can be located with the aid of the current and voltage value at the measurement end of the electrical traction line. Furthermore, the influence of the transient resistance, th...

In developing a software system, we would like to be able to estimate the way in which the fault content changes during its development, as well as determining the locations having the highest concentration of faults, In the phases prior to test, however, there maybe very little direct information regarding the number and location of faults. This lack of direct information requires the developm...

Abstract As the key equipment of power conversion, stability inverter directly affects working state equipment. Aiming at open circuit fault tube, this paper designs a diagnosis and tolerance scheme three-phase bridge based on current signal. Firstly, amplitude phase characteristics vector are used to judge location tube. Then output characteristic signal is converted into fault-tolerant contro...

This paper addresses the optimum design of fault detection systems based on sensor location. A multi-objective optimization problem based on optimal sensor location for fault detection is formulated for linear time invariant system. Measurement outputs are formed by selecting m variables of N available process measurements that ensures a high fault detetion performance. A minimum total measurem...

The paper presents an apparent impedance calculation procedure for distance relaying of transmission line involving FACTS devices, particularly the UPFC (unified power flow controller). The presence of UPFC significantly affects the trip boundaries which are also adversely affected by fault resistance combined with remote end infeed. Depending on the UPFC location, the trip boundary is influenc...

Preliminary communication There are currently no appropriate methods to find CNC system software defects and eliminate hidden dangers. In order to improve CNC system reliability, the architecture expansion-based fault location method in CNC system software was proposed in this paper. The failure of CNC system software was 619 analysed, the expansion method of CNC system software architecture wa...

Failure investigation and statistical debugging are two critical components in automated failure analysis. Although related, the two components have always been studied separately in previous work. In this paper, we propose a faultaware fingerprinting technique that relates the two components and puts them into mutualism, i.e., each component benefits and benefits from the other. Technically, w...
