The Boundary Scan Handbook

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.

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.

This pioneering text explains how to synthesize digital diagnostic sequences for wire interconnects using boundary-scan, and how to assess the quality of those sequences. It takes a new approach, carefully modelling circuit and interconnect faults, and applying graph techniques to solve problems.

In 1993, the first edition of The Electrical Engineering Handbook set a new standard for breadth and depth of coverage in an engineering reference work. Now, this classic has been substantially revised and updated to include the latest information on all the important topics in electrical engineering today. Every electrical engineer should have an opportunity to expand his expertise with this definitive guide. In a single volume, this handbook provides a complete reference to answer the questions encountered by practicing engineers in industry, government, or academia. This well-organized book is divided into 12 major sections that encompass the entire field of electrical engineering, including circuits, signal processing, electronics, electromagnetics, electrical effects and devices, and energy, and the emerging trends in the fields of communications, digital devices, computer engineering, systems, and biomedical engineering. A compendium of physical, chemical, material, and mathematical data completes this comprehensive resource. Every major topic is thoroughly covered and every important concept is defined, described, and illustrated. Conceptually challenging but carefully explained articles are equally valuable to the practicing engineer, researchers, and students. A distinguished advisory board and contributors including many of the leading authors, professors, and researchers in the field today assist noted author and professor Richard Dorf in offering complete coverage of this rapidly expanding field. No other single volume available today offers this combination of broad coverage and depth of exploration of the topics. The Electrical Engineering Handbook will be an invaluable resource for electrical engineers for years to come.

The modern electronic testing has a forty year history. Test professionals hold some fairly large conferences and numerous workshops, have a journal, and there are over one hundred books on testing. Still, a full course on testing is offered only at a few universities, mostly by professors who have a research interest in this area. Apparently, most professors would not have taken a course on electronic testing when they were students. Other than the computer engineering curriculum being too crowded, the major reason cited for the absence of a course on electronic testing is the lack of a suitable textbook. For VLSI the foundation was provided by semiconductor device techn- ogy, circuit design, and electronic testing. In a computer engineering curriculum, therefore, it is necessary that foundations should be taught before applications. The field of VLSI has expanded to systems-on-a-chip, which include digital, memory, and mixed-signalsubsystems. To our knowledge this is the first textbook to cover all three types of electronic circuits. We have written this textbook for an undergraduate “foundations” course on electronic testing. Obviously, it is too voluminous for a one-semester course and a teacher will have to select from the topics. We did not restrict such freedom because the selection may depend upon the individual expertise and interests. Besides, there is merit in having a larger book that will retain its usefulness for the owner even after the completion of the course. With equal tenacity, we address the needs of three other groups of readers.

A pragmatic approach to testing electronic systems As we move ahead in the electronic age, rapid changes in technology pose an ever-increasing number of challenges in testing electronic products. Many practicing engineers are involved in this arena, but few have a chance to study the field in a systematic way-learning takes place on the job. By covering the fundamental disciplines in detail, Principles of Testing Electronic Systems provides design engineers with the much-needed knowledge base. Divided into five major parts, this highly useful reference relates design and tests to the development of reliable electronic products; shows the main vehicles for design verification; examines designs that facilitate testing; and investigates how testing is applied to random logic, memories, FPGAs, and microprocessors. Finally, the last part offers coverage of advanced test solutions for today's very deep submicron designs. The authors take a phenomenological approach to the subject matter while providing readers with plenty of opportunities to explore the foundation in detail. Special features include: * An explanation of where a test belongs in the design flow * Detailed discussion of scan-path and ordering of scan-chains * BIST solutions for embedded logic and memory blocks * Test methodologies for FPGAs * A chapter on testing system on a chip * Numerous references

This is a new type of edited volume in the Frontiers in Electronic Testing book series devoted to recent advances in electronic circuits testing. The book is a comprehensive elaboration on important topics which capture major research and development efforts today. "Hot" topics of current interest to test technology community have been selected, and the authors are key contributors in the corresponding topics.
