Symbolic Simulation Methods for Industrial Formal Verification contains two distinct, but related, approaches to the verification problem. Both are based on symbolic simulation. The first approach is applied at the gate level and has been successful in verifying sub-circuits of industrial microprocessors with tens and even hundreds of thousands of gates. The second approach is applied at a high-level of abstraction and is used for high-level descriptions of designs. The book contains three main topics: Self consistency, a technique for deriving a formal specification of design behavior from the design itself; The use of the parametric representation to encode predicates as functional vectors for symbolic simulation, an important step in addressing the state-explosion problem; Incremental flushing, a method used to verify high-level descriptions of out-of-order execution. Symbolic Simulation Methods for Industrial Formal Verification concludes with work on verification of simplified models of out-of-order processors.

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.
Formal Verification
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
