Abstract: This paper studies a fault injection technology based on VHDL. It expounds the theories of simulation commands, saboteurs and mutants and implements them with the injection object, 8051 processor. It compares and analyzes the characters of them. For simulation commands, it studies the signal operation and variable operation styles. Aiming at the variable operation styles, it presents the feasible method. For saboteurs, it analyzes the serial saboteurs and collateral saboteurs, and proves the practical value of the serial saboteurs. For mutants, it introduces the different realizations, and presents the optimization design method.

Key words: VHDL, fault injection, simulation commands, saboteurs, mutants

摘要： 对基于VHDL的故障注入技术进行研究，阐述基于仿真命令、“破坏”和“突变”的故障注入技术原理，以8051处理器为注入对象，实现3种故障注入技术。对3种技术的特性进行比较分析。对于仿真命令方式，研究信号操作和变量操作2种方式，针对变量操作方式提出可行的实现方法。对于“破坏”方式，通过对“串行破坏”和“并行破坏”的分析比较，证明前者更具实用价值。对于“突变”方式，介绍不同的实现方法，提出优化的设计方案。
