中文摘要:

      基于VHDL的故障注入技术是一种验证系统可信性的有效方法，构造基于VHDL的故障注入工具是故障注入研究的一个重要组成部分。对基于VHDL的故障注入技术进行了研究，详细描述了该故障注入工具的结构和主要模块功能，并进行故障注入实验，分析和计算故障的激活率、探测率、恢复率。故障注入工具可用于对中等复杂度的VHDL模型进行故障注入，对容错系统的容错机制进行分析和验证。

英文摘要:

      VHDL-based fault injection technology is a useful method to validate the credibility of a system.Constructing fault injection tool based on VHDL is an important part of fault injection study.Firstly,VHDL-based fault injection techniques are studied.The structure of the fault injection tool and the main module function are described in detail,and the fault injection experiment is completed.Finally,fault activation rate,detection rate,recovery rate are analyzed and calculated.Fault injection tool can be used for the fault injection of the VHDL model of moderate complexity,and fault-tolerant systems analysis and verification of fault-tolerant mechanisms.
