摘要
ＪＴＡＧ边界扫描机制是用于在线导通测试的新技术，利用ＪＴＡＧ可以在数分钟内查出复杂插件和系统的全部导通故障。本文介绍了基于ＪＴＡＧ导通测试的基本思想，提出了一个有效的基于ＪＴＡＧ的在线导通测试算法。
JTAG Boundary Scan is a new technique for connection test.With the help of JTAG,we can find out all connection faults of a complicated board or system.In this article, we introduce the basic concepts of connection test based on the JTAG mechanism,and present an effective algorithm based on JTAG.
