集成电路测试的目的是希望在一批器件中找出有缺陷的器件，从而将交付的DPPM(每百万器件中的缺陷器件数目)降低至100以下。通过对自动测试图样生成(ATPG)算法进行一些设计修改，就可能在合理的测试图样数目下达到较高的缺陷覆盖率。本文描述了在评估不同 ...

故障建模是生产测试的基础，在介绍故障建模前需要先理清集成电路中几个容易混淆的概念：缺陷、故障、误差和漏洞。 缺陷是指在集成电路制造过程中，在硅片上所产生的物理异常，如某些器件多余或被遗漏了。故障是指由于缺陷所表现出的不同于正常功能的 ...

There is a rapidly growing interest in the use of structural techniques for testing random logic. In particular, much has been published on new techniques for on-chip compression of automatic test ...

Automatic test-pattern generation (ATPG) has played a key role in semiconductor logic test, but several trends driving the need for semiconductor test quality are challenging traditional ATPG tools.

Moore’s law has been the standard reference for semiconductor scaling. It roughly says that semiconductor design sizes, fueled by technology improvements, double every two years. Consequentially, the ...
