Download or read book Digital Circuit Testing written by Francis C. Wong and published by Elsevier. This book was released on 2012-12-02 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent technological advances have created a testing crisis in the electronics industry--smaller, more highly integrated electronic circuits and new packaging techniques make it increasingly difficult to physically access test nodes. New testing methods are needed for the next generation of electronic equipment and a great deal of emphasis is being placed on the development of these methods. Some of the techniques now becoming popular include design for testability (DFT), built-in self-test (BIST), and automatic test vector generation (ATVG). This book will provide a practical introduction to these and other testing techniques. For each technique introduced, the author provides real-world examples so the reader can achieve a working knowledge of how to choose and apply these increasingly important testing methods.

This book was released on 2007-05-08 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardware veri?cation is the process of checking whether a design conforms to its speci?cations of functionality and timing. In today’s design processes it becomes more and more important. Very large scale integrated (VLSI) circuits and the resulting digital systems have conquered a place in almost all areas of our life, even in security sensitive applications. Complex digital systems control airplanes, have been used in banks and on intensive-care units. Hence, the demand for error-free designs is more important than ever. In addition, economic reasons underline this demand as well. The design and production process of present day VLSI-circuits is highly time- and cost-intensive. Mo- over, it is nearly impossible to repair integrated circuits. Thus, it is desirable to detect design errors early in the design process and not just after producing the prototype chip. All these facts are re?ected by developing and prod- tion statistics of present day companies. For example, In?neon Technologies [118] assumed that about 60% to 80% of the overall design time was spent for veri?cation in 2000. Other sources cite the 3-to-1 head count ratio between veri?cation engineers and logic designers. This shows that verifying logical correctness of the design of hardware systems is a major gate to the problem of time-to-market (cf. [113]). With the chip complexity constantly increasing, the dif?culty as well as the - portance of functional veri?cation of new product designs has been increased. It is not only more important to get error-free designs.

Download or read book Digital System Verification written by Lun Li and published by Springer Nature. This book was released on 2022-06-01 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrated circuit capacity follows Moore's law, and chips are commonly produced at the time of this writing with over 70 million gates per device. Ensuring correct functional behavior of such large designs before fabrication poses an extremely challenging problem. Formal verification validates the correctness of the implementation of a design with respect to its specification through mathematical proof techniques. Formal techniques have been emerging as commercialized EDA tools in the past decade. Simulation remains a predominantly used tool to validate a design in industry. After more than 50 years of development, simulation methods have reached a degree of maturity, however, new advances continue to be developed in the area. A simulation approach for functional verification can theoretically validate all possible behaviors of a design but requires excessive computational resources. Rapidly evolving markets demand short design cycles while the increasing complexity of a design causes simulation approaches to provide less and less coverage. Formal verification is an attractive alternative since 100% coverage can be achieved; however, large designs impose unrealistic computational requirements. Combining formal verification and simulation into a single integrated circuit validation framework is an attractive alternative. This book focuses on an Integrated Design Validation (IDV) system that provides a framework for design validation and takes advantage of current technology in the areas of simulation and formal verification resulting in a practical validation engine with reasonable runtime. After surveying the basic principles of formal verification and simulation, this book describes the IDV approach to integrated circuit functional validation.

Available in PDF, EPUB and Kindle. Book excerpt: Device testing represents the single largest manufacturing expense in the semiconductor industry, costing over $40 billion a year. The most comprehensive and wide ranging book of its kind, Testing of Digital Systems covers everything you need to know about this vitally important subject. Starting right from the basics, the authors take the reader through automatic test pattern generation, design for testability and built-in self-test of digital circuits before moving on to more advanced topics such as IDDQ testing, functional testing, delay fault testing, memory testing, and fault diagnosis. The book includes detailed treatment of the latest techniques including test generation for various fault models, discussion of testing techniques at different levels of integrated circuit hierarchy and a chapter on system-on-a-chip test synthesis. Written for students and engineers, it is both an excellent senior/graduate level textbook and a valuable reference.

This book was released on 2007 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'objectif de ce travail de thèse consiste à fournir une démarche formelle pour la vérification de circuits numériques conçus en sécurité, c'est-à-dire qui sont prévus pour gérer certaines de leurs défaillances. Par démarche formelle, nous entendons le fait de pouvoir associer une signification mathématique et précise aux comportements des circuits numériques tant en mode normal, en l'absence de défaillance, qu'en mode dégradé, en présence de défaillances. Le but de ce travail est de permettre de déterminer dans quel contexte de défaillances un circuit numérique est sûr de fonctionnement. Le travail réalisé consiste, dans un premier temps, à enrichir un langage de spécification et de description des circuits numériques afin d'exprimer que des fautes - c'est-à-dire les causes de leurs défaillances - s'appliquent dessus et comment elles modifient le comportement des circuits numériques. Le premier objectif de cette thèse correspond donc à la formalisation des fautes de circuits numériques. Le second objectif correspond à l'élaboration d'un processus de vérification des circuits numériques en présence de fautes. Plus précisément, il s'agit de vérifier si leurs comportements sont sûrs de fonctionnement. Cet objectif est atteint en étendant les techniques de vérification existantes pour les circuits numériques.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents real-world examples of formal techniques in an industrial context. It covers formal methods such as SCADE and/or the B Method, in various fields such as railways, aeronautics, and the automotive industry. The purpose of this book is to present a summary of experience on the use of “formal methods” (based on formal techniques such as proof, abstract interpretation and model-checking) in industrial examples of complex systems, based on the experience of people currently involved in the creation and assessment of safety critical system software. The involvement of people from within the industry allows the authors to avoid the usual confidentiality problems which can arise and thus enables them to supply new useful information (photos, architecture plans, real examples, etc.).
