Abstract

Fault injection is needed for different purposes such as analyzing the reaction of a system in a faulty environment or validating fault-detection and/or fault-correction techniques. In this paper we propose a simulation-based fault injection tool able to work at different abstraction levels and with user-defined fault models. By exploiting the facilities provided by a functional verification environment it allows to speed up the entire fault injection process: from the creation of the workload to the analysis of the results of injection campaigns. Moreover, the adoption of techniques to optimize the fault list significantly reduces the simulation time. Being the tool targeted to the validation of dependable systems, it includes a way to extract information from the Failure Mode and Effect Analysis and to correlate fault injection results with estimates.

基于功能验证的故障注入环境

故障注入用于不同的目的，例如分析系统在故障环境中的反应或验证故障检测和/或故障纠正技术。在本文中，我们提出了一种基于仿真的故障注入工具，该工具能够在不同的抽象层和用户定义的故障模型中工作。通过利用功能性验证环境提供的工具，它可以加速整个故障注入过程:从创建工作负载到分析注入活动的结果。此外，采用了故障列表优化技术，大大缩短了仿真时间。作为一种针对可靠系统验证的工具，它包括一种从故障模式和影响分析中提取信息的方法，并将故障注入结果与估计相关联。
