Available in PDF, EPUB and Kindle. Book excerpt: VLSI systems are becoming very complex and difficult to test. Traditional stuck-at fault problems may be inadequate to model possible manufacturing defects in the integrated ciruit. Hierarchial models are needed that are easy to use at the transistor and functional levels. Stuck-open faults present severe testing problems in CMOS circuits, to overcome testing problems testable designs are utilized. Bridging faults are important due to the shrinking geometry of ICs. BIST PLA schemes have common features-controllability and observability - which are enhanced through additional logic and test points. Certain circuit topologies are more easily testable than others. The amount of reconvergent fan-out is a critical factor in determining realistic measures for determining test generation difficulty. Test implementation is usually left until after the VLSI data path has been synthesized into a structural description. This leads to investigation methodologies for performing design synthesis with test incorporation. These topics and more are discussed.

This book was released on 2012-12-06 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early days of digital design, we were concerned with the logical correctness of circuits. We knew that if we slowed down the clock signal sufficiently, the circuit would function correctly. With improvements in the semiconductor process technology, our expectations on speed have soared. A frequently asked question in the last decade has been how fast can the clock run. This puts significant demands on timing analysis and delay testing. Fueled by the above events, a tremendous growth has occurred in the research on delay testing. Recent work includes fault models, algorithms for test generation and fault simulation, and methods for design and synthesis for testability. The authors of this book, Angela Krstic and Tim Cheng, have personally contributed to this research. Now they do an even greater service to the profession by collecting the work of a large number of researchers. In addition to expounding such a great deal of information, they have delivered it with utmost clarity. To further the reader's understanding many key concepts are illustrated by simple examples. The basic ideas of delay testing have reached a level of maturity that makes them suitable for practice. In that sense, this book is the best x DELAY FAULT TESTING FOR VLSI CIRCUITS available guide for an engineer designing or testing VLSI systems. Tech niques for path delay testing and for use of slower test equipment to test high-speed circuits are of particular interest.

This book was released on 1987 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Functional failures of VLSI circuits are caused by process-induced defects. Such defects have very complex physical characteristics and may be significantly different from the simplistic defect models assumed by typical fault modeling techniques. In the tutorial an overview of the actual mechanisms causing processing defects, and the defects' electrical manifestations will be discussed. It will be demonstrated that inadequate insight into the physics of processing defects and the manufacturing process may lead to inefficient testing of actual VLSI circuits."

This book was released on 2012-12-06 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Test generation is one of the most difficult tasks facing the designer of complex VLSI-based digital systems. Much of this difficulty is attributable to the almost universal use in testing of low, gate-level circuit and fault models that predate integrated circuit technology. It is long been recognized that the testing prob lem can be alleviated by the use of higher-level methods in which multigate modules or cells are the primitive components in test generation; however, the development of such methods has proceeded very slowly. To be acceptable, high-level approaches should be applicable to most types of digital circuits, and should provide fault coverage comparable to that of traditional, low-level methods. The fault coverage problem has, perhaps, been the most intractable, due to continued reliance in the testing industry on the single stuck-line (SSL) fault model, which is tightly bound to the gate level of abstraction. This monograph presents a novel approach to solving the foregoing problem. It is based on the systematic use of multibit vectors rather than single bits to represent logic signals, including fault signals. A circuit is viewed as a collection of high-level components such as adders, multiplexers, and registers, interconnected by n-bit buses. To match this high-level circuit model, we introduce a high-level bus fault that, in effect, replaces a large number of SSL faults and allows them to be tested in parallel. However, by reducing the bus size from n to one, we can obtain the traditional gate-level circuit and models.

Download or read book Introduction to IDDQ Testing written by S. Chakravarty and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Testing techniques for VLSI circuits are undergoing many exciting changes. The predominant method for testing digital circuits consists of applying a set of input stimuli to the IC and monitoring the logic levels at primary outputs. If, for one or more inputs, there is a discrepancy between the observed output and the expected output then the IC is declared to be defective. A new approach to testing digital circuits, which has come to be known as IDDQ testing, has been actively researched for the last fifteen years. In IDDQ testing, the steady state supply current, rather than the logic levels at the primary outputs, is monitored. Years of research suggests that IDDQ testing can significantly improve the quality and reliability of fabricated circuits. This has prompted many semiconductor manufacturers to adopt this testing technique, among them Philips Semiconductors, Ford Microelectronics, Intel, Texas Instruments, LSI Logic, Hewlett-Packard, SUN microsystems, Alcatel, and SGS Thomson. This increase in the use of IDDQ testing should be of interest to three groups of individuals associated with the IC business: Product Managers and Test Engineers, CAD Tool Vendors and Circuit Designers. Introduction to IDDQ Testing is designed to educate this community. The authors have summarized in one volume the main findings of more than fifteen years of research in this area.

Download or read book IDDQ Testing of VLSI Circuits written by Ravi K. Gulati and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power supply current monitoring to detect CMOS IC defects during production testing quietly laid down its roots in the mid-1970s. Both Sandia Labs and RCA in the United States and Philips Labs in the Netherlands practiced this procedure on their CMOS ICs. At that time, this practice stemmed simply from an intuitive sense that CMOS ICs showing abnormal quiescent power supply current (IDDQ) contained defects. Later, this intuition was supported by data and analysis in the 1980s by Levi (RACD, Malaiya and Su (SUNY-Binghamton), Soden and Hawkins (Sandia Labs and the University of New Mexico), Jacomino and co-workers (Laboratoire d'Automatique de Grenoble), and Maly and co-workers (Carnegie Mellon University). Interest in IDDQ testing has advanced beyond the data reported in the 1980s and is now focused on applications and evaluations involving larger volumes of ICs that improve quality beyond what can be achieved by previous conventional means. In the conventional style of testing one attempts to propagate the logic states of the suspended nodes to primary outputs. This is done for all or most nodes of the circuit. For sequential circuits, in particular, the complexity of finding suitable tests is very high. In comparison, the IDDQ test does not observe the logic states, but measures the integrated current that leaks through all gates. In other words, it is like measuring a patient's temperature to determine the state of health. Despite perceived advantages, during the years that followed its initial announcements, skepticism about the practicality of IDDQ testing prevailed. The idea, however, provided a great opportunity to researchers. New results on test generation, fault simulation, design for testability, built-in self-test, and diagnosis for this style of testing have since been reported. After a decade of research, we are definitely closer to practice.
