Boundary-Scan, formally known as IEEE/ANSI Standard 1149.1-1990, is a collection of design rules applied principally at the Integrated Circuit (IC) level that allow software to alleviate the growing cost of designing, producing and testing digital systems. A fundamental benefit of the standard is its ability to transform extremely difficult printed circuit board testing problems that could only be attacked with ad-hoc testing methods into well-structured problems that software can easily deal with. IEEE standards, when embraced by practicing engineers, are living entities that grow and change quickly. The Boundary-Scan Handbook, Second Edition: Analog and Digital is intended to describe these standards in simple English rather than the strict and pedantic legalese encountered in the standards. The 1149.1 standard is now over eight years old and has a large infrastructure of support in the electronics industry. Today, the majority of custom ICs and programmable devices contain 1149.1. New applications for the 1149.1 protocol have been introduced, most notably the `In-System Configuration' (ISC) capability for Field Programmable Gate Arrays (FPGAs). The Boundary-Scan Handbook, Second Edition: Analog and Digital updates the information about IEEE Std. 1149.1, including the 1993 supplement that added new silicon functionality and the 1994 supplement that formalized the BSDL language definition. In addition, the new second edition presents completely new information about the newly approved 1149.4 standard often termed `Analog Boundary-Scan'. Along with this is a discussion of Analog Metrology needed to make use of 1149.1. This forms a toolset essential for testing boards and systems of the future.

Boundary-Scan, formally known as IEEE/ANSI Standard 1149.1-1990, is a collection of design rules applied principally at the integrated circuit (IC) level that allow software to alleviate the growing cost of designing and producing digital systems. The primary benefit of the standard is its ability to transform extremely printed circuit board testing problems that could only be attacked with ad-hoc testing methods into well-structured problems that software can easily and swiftly deal with. The Boundary-Scan Handbook is for professionals in the electronics industry who are concerned with the practical problems of competing successfully in the face of rapid-fire technological change. Since many of these changes affect our ability to do testing and hence cost-effective production, the advent of the 1149.1 standard is rightly looked upon as a major breakthrough. However, there is a great deal of misunderstanding about what to expect of 1149.1 and how to use it. Because of this, The Boundary-Scan Handbook is not a rehash of the 1149.1 standard, nor does it intend to be a tutorial on the basics of its workings. The standard itself should always be consulted for this, being careful to follow supplements issued by the IEEE that clarify and correct it. Rather, The Boundary-Scan Handbook motivates proper expectations and explains how to use the standard successfully.

In February of 1990, the balloting process for the IEEE proposed standard P1149.1 was completed creating IEEE Std 1149.1-1990. Later that summer, in record time, the standard won ratification as an ANSI standard as well. This completed over six years of intensive cooperative effort by a diverse group of people who share a vision on solving some of the severe testing problems that exist now and are steadily getting worse. Early in this process, someone asked me if 1 thought that the P1l49.l effort would ever bear fruit. 1 responded somewhat glibly that "it was anyone's guess". Well, it wasn't anyone's guess, but rather the faith of a few individuals in the proposition that many testing problems could be solved if a multifaceted industry could agree on a standard for all to follow. Four of these individuals stand out; they are Harry Bleeker, Colin Maunder, Rodham Tulloss, and Lee Whetsel. In that I am convinced that the 1149.1 standard is the most significant testing development in the last 20 years, I personally feel a debt of gratitude to them and all the people who labored on the various Working Groups in its creation.
