| 摘 要： | 针对航天应用的处理器敏感性评估需求,采用仿真命令技术开发了一种基于VHDL的故障注入工具.以LEON3处理器为目标模型进行了故障注入实验,得到了流水线寄存器的敏感性,并对敏感性较高的寄存器加固之后再次进行可靠性评估,从而验证了该故障注入工具的有效性.本故障注入工具适用于基于VHDL的RTL级处理器的软错误敏感性分析.

| Abstract: | A fault injection tool based on VHDL that implemented by simulator commands technique is proposed for supporting the sensitivity analysis of space processor.To demonstrate the tool,we use LEON3 processor as the target prototype to obtain the sensitivity of pipeline registers.Moreover,we harden the pipeline registers which are most sensitive and evaluate the reliability again.The fault injection tool presented by this paper can be also used to analyze sensitivity for other processor models by VHDL. |
