边界扫描测试协议剖析——从1149.1到1149.6

Boundary-Scan Test Standard\;——from 1149.1 to 1149.6

本文对边界扫描协议IEEEStd 114 9.1- 1990到IEEEStd 114 9.6 - 2 0 0 3的多个协议进行了介绍和剖析 ,着重讨论了各个协议能够解决的问题以及解决问题的方法 ,各个协议的体系结构和指令特色 ,总结了边界扫描技术的最新进展 ,并对以后边界扫描的发展方向给出了预测。

In this paper, Boundary-scan Test Standards IEEE Std 1149.1 to 1149.6 are introduced. It focuses on architecture and characteristic of instruction. After analysis of the new development of boundary-scan techniques, the future direction of boundary-scan techniques is expected.
