摘　　要：测试性模型是进行测试性仿真、设计、分析、评估等的基础和关键.本文介绍了测试性工程及测试性模型的研究背景.较为系统地阐述了逻辑模型、信息流模型、多信号流图模型、混合诊断模型等测试性模型的组成、相关软件、应用概况等,介绍了这些模型的研究进展,并以某有源滤波放大电路为案例,直观、深入地分析、比较各类模型的特点.指出测试性工程对测试性模型提出的新要求及目前测试性模型存在的一些不足,提出将虚拟样机技术引入测试性建模领域,研究面向测试性的虚拟样机,构建定量化的测试性模型将是未来的发展趋势,并给出了面向测试性的虚拟样机的框架结构和组成.Testability model is the basic and critical factor in the testability simulation, design, analysis and evaluation. Firstly, the background of the testability engineering and testability model is introduced. Secondly, some typical testability models, such as logic model, information flow model, multisignal flow graphs model, structure model and hybrid diagnostic model, are discussed. The elements, correlative software and application of these models are elaborated. The characteristics of these models are compared and analyzed with an active filter/amplifier as an example. Finally, the disadvantages of current testability models are indicated. And the paper points out that introducing virtual prototyping technology into testability modeling field and studying testability - oriented virtual prototype will become the tendency d testability model. Simultaneously the frame of the testability- oriented virtual prototype is presented.
