摘要: 为了对分层系统进行测试性分析,提出基于多信号流图模型的分层系统测试性建模与分析方法.该方法利用多信号流图模型建立分层系统的层次结构模型,进行测试性分析时,首先利用相关性模型法对顶层模型进行测试性分析,当层次性模块与其它模块不能区分时,再利用相关性模型法对模糊组进行测试性分析,最终实现对分层系统的诊断设计.最后,利用某具有层次性结构的滤波放大器电路对该方法进行了验证,试验结果证明,该方法对于分层系统的测试性建模与分析是有效的,能够为分层系统制定有效的诊断策略.

Abstract: In order to make analysis for testability of hierarchy system, a testability modeling and analyzing approach were proposed for hierarchy system based on multi-signal flow graph (MSFG). This approach can used MSFG to build hierarchy system-s hierarchy structural mode. Firstly, dependency model was applied to make testability analysis for the top-model. If the hierarchy module can-t be isolated with other modules, the dependency model was used to make testability analysis for the ambiguity again, continuing this process until realizing diagnostic designing of the whole hierarchy system. Finally, by applying the proposed approach in some hierarchy structural amplifier/filter system, the efficiency of this method was verified, and the result shows that this method is efficient, and effective diagnostic strategy can be obtained for the testability analysis of hierarchy system.
