测试性建模与分析在显示控制单元中的应用

摘要

测试性分析与评估是测试性设计工作的重要环节，采用的方法一般有基于经验的加权法和基于模型的分析法。本文采用了基于模型的方法对显示控制单元的测试性进行了分析与评估，验证了显示控制单元的测试性设计指标是否达到要求，并对显示控制单元的测试性设计提出了改进建议。%Analysis and evaluation of testability is an important link of design for testability,methods generally used are weighted method based on experience and model-analysis method . A model-based approach was used in this article to testability analysis and evaluation for display control unit, verifying that the display control unit testability design specification meets the requirements. In the end, testability design improvement suggestion for display control unit are presented.
