【摘要】：故障注入技术是评价系统可靠性的有效方法。现有基于仿真的故障注入平台大多基于现场可编程门阵列或超高速集成电路硬件描述语言实现,对故障模型的支持非常有限。为此,基于Simics结构级模拟器,设计并实现系统级硬件故障注入平台。该平台上层支持不同固件、操作系统以及应用程序,底层支持对处理器典型流水部件的故障注入,同时实现瞬时故障、永久故障和间歇故障模型以及其他较全面的故障类型,并将一组系统级故障检测机制集成入平台中。实验通过监测硬件故障在系统级的传播,对比分析了故障对不同部件造成的系统级影响,结果表明,瞬时故障对系统影响较小,永久故障容易引起系统失效,间歇故障对各部件有不同程度的干扰作用。
[Abstract]:Fault injection technique is an effective method to evaluate the reliability of the system. Most of the existing simulation-based fault injection platforms are based on field programmable gate arrays or VLSI hardware description language, and the support for fault models is very limited. Therefore, the system level hardware fault injection platform is designed and implemented based on Simics structural simulator. The upper layer of the platform supports different firmware, operating systems and applications, while the bottom layer supports fault injection of typical pipelined components of the processor, and implements transient, permanent and intermittent fault models as well as other more comprehensive fault types. A set of system level fault detection mechanisms are integrated into the platform. By monitoring the propagation of hardware fault at the system level, the system level effect caused by the fault on different components is compared and analyzed. The results show that the transient fault has little effect on the system, and the permanent fault can easily cause the system failure. Intermittent faults have different degree of interference to each component.
