摘　　要：主要论述了在Simics全系统仿真环境下,对Vx Works嵌入式操作系统的串口故障注入以及网络故障注入的相关研究。Simics允许开发者根据需求自定义处理器、存储器、板级硬件和复杂网络系统等任意规模的硬件目标设备模型。运行在真实硬件目标设备上的底层软件、中间层软件和上层软件完全不用修改即可运行在自定义的Simics硬件目标设备模型上。因此,Simics不仅能够进行仿真硬件级的故障注入,同时还可以全面地检测软件的运行状态。This paper discusses the research of the VxWorks embedded operating system＇s serial port fault injection and net- work fault injection under Simics full system simulation environment. Simics enables developers to customize processors, memory, board-level hardware and complex network systems and any-size hardware target device models based on their needs. The underly- ing software, middle-layer software and upper-layer software running on real hardware target devices can run on Simics target hardware device models without any modification. Therefore, Simics not only enables hardware-level fault injection simulation, but also can fully detect the operating state of the software.
