摘要

In this paper we propose an approach to speed-up Fault Injection campaigns for the evaluation of dependability properties of complex digital systems. The approach exploits FPGA devices for system emulation, and new techniques are described, allowing emulating the effects of faults and to observe faulty behavior. Thanks to its flexibility and efficiency, the approach is suitable to be applied to SOC devices. The paper points out the flexibility of the approach, able to inject different faults of different types in custom logic, memory blocks, and processor cores. The proposed approach combines the speed of hardware-based techniques, and the flexibility of simulation-based techniques. Experimental results are provided showing that speed-up figures of up to 3 orders of magnitude with respect to state-of-the-art simulation-based techniques can be achieved.
