This paper will describe a fault simulation tool for analogue and mixed-signal circuits based on the HSpice circuit simulator and a graphical user interface (GUI)/Integration tool created using Tcl/Tk. The structure and use of the tool is demonstrated with example to the fault-free and fault simulation of a weighted-current Digital to Analogue Converter (DAC). Fault simulation techniques utilis...

AESTRACT We introduce a new fault representation mechanism for digital circuits based on fault tuples. A fault tuple is a simple 3-element condition for a signal line, its value, and clock cyclle constraint. AND-OR expressions of fault tuples are used to represent arbitrary misbehaviors. A fault simulator based on fault tuples was used to conduct experiments on benchmark circuits. Simulation re...

We propose three synchronous parallel algorithms for scalable parallel test set partitioned fault simulation. The algorithms are based on a new two-stage approach to parallelizing fault simulation for sequential VLSI circuits in which the test set is partitioned among the available processors. The test set partitioning inherent in the algorithms overcomes the good circuit logic simulation bottl...

In this study, detection and identification of common faults in industrial gas turbines is investigated. We propose a model-based robust fault detection(FD) method based on multiple models. For residual generation a bank of Local Linear Neuro-Fuzzy (LLNF) models is used. Moreover, in fault detection step, a passive approach based on adaptive threshold is employed. To achieve this purpose, the a...

this paper presents the hardware simulation (based on vhdl code) of a multiple-fault tolerant cellular genetic algorithm. this study aims to increase the immunity of cellular genetic algorithm in multiple-fault situation. here, multiple-fault refers to the situation that seu (single event upset) occurs simultaneously at two or more bits of the chromosome and fitness registers. the fault model i...

tern generation (ATPG) has yielded effective solutions for combinational circuits, developing efficient methods for sequential circuits remains difficult. The difficulty results because state and time frame expansion has caused a virtual explosion of the relevant search space. The commonly used branch-and-bound technique1 is infeasible for large sequential circuits because of the exponentially ...

among the studies related to power systems are the contingency analysis for judging the system security and short circuit study for relay coordination. due to continuous and repeated performation of these studies for different system configurations, the solution algorithms but also on applied numerical techniques. compensation and partial matrix refactorization are two methods that are often us...
