Environment for Fault Simulation Acceleration on FPGA

چکیده
We present an environment to accelerate fault simulation by hardware emulation on FPGA. Fault simulation is an important subtask in test pattern generation and it is frequently used throughout the test generation process. We studied the feasibility of using reconfigurable hardware emulator instead of software simulation. Experiments showed that it is beneficial to use emulation for circuits/methods that require large numbers of test vectors, e.g., sequential circuits and/or genetic algorithms.

Simulation-based Vibration Sensor Placement for Centrifugal Pump Impeller Fault Detection
In this paper, a simulation-based method is proposed for optimal placement of vibration sensors for the purpose of fault detection in a centrifugal pump. The centrifugal pump is modeled to investigate the effect of vane tip fault on fluid flow patterns numerically. Pressure pulsations are investigated at different locations at the inner surface of the pump before and after the presence of the f...

متن کاملCo - design of Fault - Tolerant Systems with Imperfect Fault Detection
In recent decades, transient faults have become a critical issue in modern electronic devices. Therefore, many fault-tolerant techniques have been proposed to increase system reliability, such as active redundancy, which can be implemented in both space and time dimensions. The main challenge of active redundancy is to introduce the minimal overhead of redundancy and to schedule the tasks. In m...
