In a chapter devoted to recent developments, the Boundary-Scan Tutorial describes the objectives of the IEEE P1687 working group, which is investigating the development of the so-called Internal JTAG (IJTAG) standard. When ratified, IJTAG would standardize the way an external system could communicate with embedded design debug and test instruments via the 1149.1 test access port (TAP). System-level JTAG issues are also discussed as well as how boundary-scan technology relates to other test technologies such as processor-based emulation testing, in-circuit test (ICT), flying probe testers (FPT) and others. The tutorial also features a chapter on device- and board-level design-for-test (DFT) guidelines.
Earlier editions of the Boundary-Scan Tutorial have been widely distributed to test engineers, technicians and managers. The new edition contains 75 pages with more than 70 illustrations, a bibliography and a list of reference materials.

About ASSET InterTech
ASSET's boundary-scan systems, ScanWorks� and DFT Analyzer�, have advanced usability and automation features. ScanWorks has become the boundary-scan test system of choice for practically all major communication and defense/avionics suppliers, including Cisco, Ericsson, Motorola, Lucent, Alcatel, Tellabs, Huawei, Raytheon, Rockwell, Lockheed Martin, BAE, ITT, Northrop Grumman, Smiths and others. In addition, ScanWorks' adoption by companies like Microsoft for its Xbox 360 video game console and Delphi for its automotive electronics demonstrates that ScanWorks will continue its leadership as boundary scan proliferates in computers, set-top boxes, consumer electronics, industrial controls, automotive and other industries.
ASSET InterTech, Inc. develops, markets, sells, and supports boundary-scan testability, in-system programming (ISP) and design-for-test products worldwide. ASSET's affordable ScanWorks and DFT Analyzer systems are easy yet powerful. ScanWorks allows users to quickly and easily test semiconductors, circuit boards or entire systems during every phase of a product's life, including design, manufacturing/repair and field maintenance and to program chips after they have been connected to a circuit board. DFT Analyzer is the industry's first tool to validate the JTAG testability features of a design. ScanWorks and DFT Analyzer work in conjunction with a standard of the International Electronics and Electrical Engineering (IEEE) society known as the IEEE 1149.1 (JTAG) boundary-scan test specification. ASSET InterTech is located outside of Dallas, TX, at 2201 North Central Expressway, Suite 105, Richardson, TX 75080.
