本文介绍了一种用于测试模式生成的新方法,以用于内置的内置自我测试。新颖性在于原始测试序列检测到打开,短裤和延迟以及测试模式发生器的原始设计。主要思想是基于使用圆形移位寄存器及其适当的初始化。与其他已知技术相比,当前方法在最短的测试应用程序时提供了最低的硬件成本。
This article describes a novel approach to test pattern generation for at-speed interconnect built-in self-test. The novelty consists in both the original test sequence detecting opens, shorts and delays and the original design of the test pattern generator. The main idea is based on using a circular shift register and its proper initialization. Compared to other known techniques, Current approach provides the minimal hardware cost at the shortest test application time.
