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.

Book Synopsis Formal Verification by : Erik Seligman
Download or read book Formal Verification written by Erik Seligman and published by Morgan Kaufmann. This book was released on 2015-07-24 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Formal Verification: An Essential Toolkit for Modern VLSI Design presents practical approaches for design and validation, with hands-on advice to help working engineers integrate these techniques into their work. Formal Verification (FV) enables a designer to directly analyze and mathematically explore the quality or other aspects of a Register Transfer Level (RTL) design without using simulations. This can reduce time spent validating designs and more quickly reach a final design for manufacturing. Building on a basic knowledge of SystemVerilog, this book demystifies FV and presents the practical applications that are bringing it into mainstream design and validation processes at Intel and other companies. After reading this book, readers will be prepared to introduce FV in their organization and effectively deploy FV techniques to increase design and validation productivity. Learn formal verification algorithms to gain full coverage without exhaustive simulation Understand formal verification tools and how they differ from simulation tools Create instant test benches to gain insight into how models work and find initial bugs Learn from Intel insiders sharing their hard-won knowledge and solutions to complex design problems

Download or read book Scalable Techniques for Formal Verification written by Sandip Ray and published by Springer Science & Business Media. This book was released on 2010-08-12 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about formal veri?cation, that is, the use of mathematical reasoning to ensure correct execution of computing systems. With the increasing use of c- puting systems in safety-critical and security-critical applications, it is becoming increasingly important for our well-being to ensure that those systems execute c- rectly. Over the last decade, formal veri?cation has made signi?cant headway in the analysis of industrial systems, particularly in the realm of veri?cation of hardware. A key advantage of formal veri?cation is that it provides a mathematical guarantee of their correctness (up to the accuracy of formal models and correctness of r- soning tools). In the process, the analysis can expose subtle design errors. Formal veri?cation is particularly effective in ?nding corner-case bugs that are dif?cult to detect through traditional simulation and testing. Nevertheless, and in spite of its promise, the application of formal veri?cation has so far been limited in an ind- trial design validation tool ?ow. The dif?culties in its large-scale adoption include the following (1) deductive veri?cation using theorem provers often involves - cessive and prohibitive manual effort and (2) automated decision procedures (e. g. , model checking) can quickly hit the bounds of available time and memory. This book presents recent advances in formal veri?cation techniques and d- cusses the applicability of the techniques in ensuring the reliability of large-scale systems. We deal with the veri?cation of a range of computing systems, from - quential programsto concurrentprotocolsand pipelined machines.
Book Synopsis Design and Verification of Microprocessor Systems for High-Assurance Applications by : David S. Hardin
Download or read book Design and Verification of Microprocessor Systems for High-Assurance Applications written by David S. Hardin and published by Springer Science & Business Media. This book was released on 2010-03-02 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microprocessors increasingly control and monitor our most critical systems, including automobiles, airliners, medical systems, transportation grids, and defense systems. The relentless march of semiconductor process technology has given engineers exponentially increasing transistor budgets at constant recurring cost. This has encouraged increased functional integration onto a single die, as well as increased architectural sophistication of the functional units themselves. Additionally, design cycle times are decreasing, thus putting increased schedule pressure on engineers. Not surprisingly, this environment has led to a number of uncaught design flaws. Traditional simulation-based design verification has not kept up with the scale or pace of modern microprocessor system design. Formal verification methods offer the promise of improved bug-finding capability, as well as the ability to establish functional correctness of a detailed design relative to a high-level specification. However, widespread use of formal methods has had to await breakthroughs in automated reasoning, integration with engineering design languages and processes, scalability, and usability. This book presents several breakthrough design and verification techniques that allow these powerful formal methods to be employed in the real world of high-assurance microprocessor system design.

This book was released on 1996 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "The design of correct computer systems is extremely difficult. However, it is also a very important task. Such systems are frequently used in applications where failures can have catastrophic consequences, or cause significant financial losses. Simulation and testing are the most widely used verification techniques, but they can only show the presence of errors and cannot demonstrate correctness. Until lately formal methods were too expensive to be used in industrial problems, but recent research has made it possible to apply formal techniques to the verification of complex real-world systems. Symbolic model checking is an example of such a technique that has been successful in verifying large finite-state systems. It has also been extended to produce timing and performance information. These properties are extremely important in the design of high-performance systems and time-critical applications. A more detailed analysis of a model is possible using these extensions than by simply determining whether a property is satisfied or not. We present algorithms that determine the exact bounds on the delay between two specified events and the number of occurrences of another event in all such intervels. To demonstrate how our method works, we present two complex examples: the verification of the Futurebus+ cache coherence protocol and the timing analysis of the PCI local bus. These results show the usefulness of symbolic model checking in analyzing modern industrial designs."

Book Synopsis Formal Verification of Circuits by : Rolf Drechsler
Download or read book Formal Verification of Circuits written by Rolf Drechsler and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Formal verification has become one of the most important steps in circuit design. Since circuits can contain several million transistors, verification of such large designs becomes more and more difficult. Pure simulation cannot guarantee the correct behavior and exhaustive simulation is often impossible. However, many designs, like ALUs, have very regular structures that can be easily described at a higher level of abstraction. For example, describing (and verifying) an integer multiplier at the bit-level is very difficult, while the verification becomes easy when the outputs are grouped to build a bit-string. Recently, several approaches for formal circuit verification have been proposed that make use of these regularities. These approaches are based on Word-Level Decision Diagrams (WLDDs) which are graph-based representations of functions (similar to BDDs) that allow for the representation of functions with a Boolean range and an integer domain. Formal Verification of Circuits is devoted to the discussion of recent developments in the field of decision diagram-based formal verification. Firstly, different types of decision diagrams (including WLDDs) are introduced and theoretical properties are discussed that give further insight into the data structure. Secondly, implementation and minimization concepts are presented. Applications to arithmetic circuit verification and verification of designs specified by hardware description languages are described to show how WLDDs work in practice. Formal Verification of Circuits is intended for CAD developers and researchers as well as designers using modern verification tools. It will help people working with formal verification (in industry or academia) to keep informed about recent developments in this area.

Book Synopsis Symbolic Model Checking by : Kenneth L. McMillan
Download or read book Symbolic Model Checking written by Kenneth L. McMillan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Formal verification means having a mathematical model of a system, a language for specifying desired properties of the system in a concise, comprehensible and unambiguous way, and a method of proof to verify that the specified properties are satisfied. When the method of proof is carried out substantially by machine, we speak of automatic verification. Symbolic Model Checking deals with methods of automatic verification as applied to computer hardware. The practical motivation for study in this area is the high and increasing cost of correcting design errors in VLSI technologies. There is a growing demand for design methodologies that can yield correct designs on the first fabrication run. Moreover, design errors that are discovered before fabrication can also be quite costly, in terms of engineering effort required to correct the error, and the resulting impact on development schedules. Aside from pure cost considerations, there is also a need on the theoretical side to provide a sound mathematical basis for the design of computer systems, especially in areas that have received little theoretical attention.
