Boundary-Scan Test: A Practical Approach Review

Costs 50% more than Parker's "The Boundary-Scan Handbook", is much more difficult to read, and has less useful information. There are frequent typographical errors, and the material is disorganized - for example, the section describing the INTEST command neglects to mention that 1149.1 requires that the chip's inner circuitry must be single-steppable - single-stepping for INTEST is only indirectly referred to in a later section describing RUNBIST. Many of the 1149.1 requirements aren't integrated with the main discussion of a topic where they could be most readily digested, but are relegated to an appendix that appears to be something of an afterthought.

This new book will act an introduction to as well as apractical guide to Boundary-Scan testing. The ever increasingminiaturization of digital electronic components is hampering theconventional testing of Printed Circuit Boards (PCBs) by means ofbed-of-nails fixtures. Basically this is caused by the very high scaleof integration of ICs, through which packages with hundreds of pins atvery small pitches of down to a fraction of a millimeter, have becomeavailable. As a consequence, the trace distances between the coppertracks on a printed circuit board came down to the same value. Notonly have the required small physical dimensions of the test nailsmade conventional testing unfeasible, the complexity to provide testsignals for many hundreds of test nails has grown beyond manageablelimits. A new board test methodology has to be invented. Following theevolution in the IC test technology, Boundary-Scan testing has becomethe new approach to PCB testing. By taking precautions in the designof the IC (design for testability), testing on a PCB level could besimplified to a great extent. This condition has been essential forthe success of the introduction of a Boundary-Scan Test (BST) at boardlevel. Since Boundary-Scan testing involves the whole PCB life cycle, it ismore than just the introduction of a new design technology. It is anintegral production approach which will aid top management in theirgoal of a successful global strategy for their business. This book will aid a company to introduce the Boundary-Scan Test. ICdesign and test engineers alike will find the book an importantintroduction and guide to using the Boundary-Scan Test in their work.Engineering managers can also use this book to gain an insight to theimpact that the Boundary-Scan Test will make on their organisation.
