With the advent of new the RT-level design and test flows, new tools are needed to migrate at the RT-level the activities of fault simulation, testability analysis, and test pattern generation. This paper focuses on fault simulation at the RT-level, and aims at exploiting the capabilities of VHDL simulators to compute faulty responses. The simulator was implemented as a prototypical tool, and e...

Advanced Encryption Standard (AES) cryptographic system are widely used in embedded systems to secure secret information. One of the most powerful cryptanalysis techniques against the cryptographic systems is the fault injection attacks. The complexity of cryptographic systems is increasing which requires fast security attacks simulation against fault injection attacks. The multi-level Electron...

In this paper, the fuzzy system has been used for fault detection and diagnosis of a yeast fermentation bioreactor based on measurements corrupted by noise. In one case, parameters of membership functions are selected in a conventional manner. In another case, using certainty factors between normal and faulty conditions the optimal values of these parameters have been obtained through the g...

System reliability is an important issue in designing modern multiprocessor systems. This paper proposes a fault-tolerant, scalable, system architecture that adopts pipeline scheme. To verify the performance of proposed system, SimEvent/Stateflow tool MATLAB program was used to simulate system. The uses twelve processors (P), connected linear array, build ten-stage with two backup (BP). However...

This paper describes the RaFT simulation environment, a software tool for use in the development of hardware-based fault-tolerant systems using transputers. The concepts behind the RaFT project are presented, together with an overview of previous work into the design of a fault-tolerant transputer node. The simulation environment described seeks to emulate the hardware techniques and to provide...

Fault simulation for synchronous sequential circuits is a very time-consuming task. The complexity of the task increases if there is no information available about the initial state of the circuit. In this case, an unknown initial state is assumed which is usually handled by introducing a three-valued logic. It is known that fault simulation based upon this logic only determines a lower bound f...

wireless sensor networks (wsns) consist of a large number of sensor nodes which are capable of sensing different environmental phenomena and sending the collected data to the base station or sink. since sensor nodes are made of cheap components and are deployed in remote and uncontrolled environments, they are prone to failure; thus, maintaining a network with its proper functions even when und...

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...

Fault diagnosis techniques for digital integrated circuits have been classified into three categories: static (using pre-computed information), dynamic (using simulation at run-time) and integrated (using a combination of pre-computed information and simulation). This paper presents our research in all three areas. We first present our tree-based theoretical framework, which improves static fau...

We simulate a stabilizing propagation of information with feedback (PIF) program to evaluate its response to perturbations. Under several classic execution models, we vary the extent of the fault as well as the system scale. We study the program’s speed of stabilization and overhead incurred by the fault. Our simulation provides insight into practical program behavior that is sometimes lacking ...
