2003年9月15日 · Several members of the IEEE 1149.6 working group describe how the standard works and how it can test Gigabit Ethernet, Fibre Channel and more. AC-coupled high-speed differential signals have been a hole in the IEEE 1149.1 boundary-scan standard since its …

IEEE 1149.6标准的基本实现需要在信号路径驱动器中添加一个时脉产生器，它能发射单一脉冲或一列脉冲，这取决于被加载到 1149.1 指令暂存器中的 EXTEST_PULSE 或 EXTEST_TRAIN 指令。

2016年3月18日 · Scope: This standard defines extensions to IEEE Std 1149.1 (TM) to standardize the boundary-scan structures and methods required to help ensure simple, robust, and minimally intrusive boundary-scan testing of advanced digital networks.

2009年9月11日 · This standard defines extensions to IEEE Std 1149.1. It standardizes the boundary-scan structures and methods required to help ensure simple, robust, and minimally intrusive boundary-scan testing of advanced digital networks.

Its work, approved and published as IEEE 1149.6 Standard for Boundary-Scan Testing of Advanced Digital Networks, specifies supplemental boundary-scan cells for provision on advanced digital networks and corresponding boundary-scan instructions that are capable of generating stimuli and capturing responses in a manner suitable to the presence of ...

2003年9月30日 · The IEEE 1149.6 standard was approved in March of 2003. The standard extends the capability of the IEEE 1149.1 standard to include AC-coupled and/or differential nets. These nets are predominant in multi-gigabit serial technology. This paper presents a short overview of the 1149.6 standard and the issues that it addresses.

2024年11月28日 · IEEE 1149.6标准的基本实现需要在信号路径 驱动器 中添加一个时脉产生器，它能发射单一脉冲或一列脉冲，这取决于被加载到 1149.1 指令暂存器中的 EXTEST_PULSE 或 EXTEST_TRAIN 指令。

2022年7月22日 · 本文详细介绍了JTAG 1149.6协议，作为1149.1协议的扩展，专注于交流耦合I/O测试。 内容涵盖协议新增的EXTEST_PULSE和EXTEST_TRAIN指令，以及AC边界扫描结构，旨在支持高级I/O引脚的AC测试和差分信号引脚的连接检查。 JTAG 1149.6协议是1149.1协议中Boundary-Scan结构的扩展，1149.1对交流耦合、差分或两者兼有的情况并没有得到充分的处理。 该协议支持新的I/O测试结构。 需要时变 (AC)信号的高级I/O引脚允许测试它们之间的连接， …
