A summary, overview or tutorial of the basics of what is boundary scan, JTAG, IEEE 1149 (IEEE 1149.1), test system used for testing complex electronic circuits where there is limited test access.
on the PCBA. An external JTAG/boundary-scan controller is used to activate the logic and complete the testing of the board and programming of devices. Using the JTAG/boundary-scan logic minimizes the amount and complexity of equipment for testing boards and for device programming in design, manu...
JTAG - the IEEE 1149.1 Standard JTAG/Boundary Scanor theIEEE 1149.1standard is one of the most successful electronics standards of all time and was invented to test electrical assemblies. JTAG/Boundary Scan has become an integral part of electronics development and production. ...
Boundary scan is going crazy. From humble beginnings in 1990 targeted at solving the limited-access problems of traditional board test based on a physical-touch technology such as bed-of-nails and flying probe systems, IEEE 1149.1 boundary scan applications have expanded beyond the wildest ...

用于JTAG测试而特意加入设备中的主要寄存器叫作边界扫描寄存器(Boundary Scan Register)。 正如它名字所提示的那样,这个寄存器中的单个模块,或者单元,都位于设备的边界上,在它的功能核心和与板卡相连的针脚或焊点之间——很多时候 JTAG测试被称为边界扫描。
How XJTAG uses JTAG/boundary scan to test a board Boundary scan cells (see above) can operate in two modes. In their functional mode they have no effect on the operation of the device – this is the mode in which they operate when the board is running normally. In their test mode the...
