摘要
IEEE1149标准及其子标准是基于边界扫描的测试技术,它们针对不同的应用环境采用相应的技术标准。它们所提供的解决方案极大地方便了芯片级、板级、系统级及数字网络的测试。本文讨论了IEEE1149.X中各标准的原理、结构,分析了各项技术的发展及应用,并举例说明了在实际中的测试应用。
IEEE1149 standard and its .X sub standards are based on boundary scan technique, different standards can be appropriately selected for various of applications. The standards provide more solutions to the test of IC level, board level, system level and digital networks, which facilitate the debugging and testing of them. In the paper the theory and architecture of IEEE1149.X standards will be discussed, then their development and applications will be analysed, and their applications in practice will be pointed out.
