Book Description
In order to design and build computers that achieve and sustain high performance, it is essential that reliability issues be considered care fully. The problem has several aspects. Certainly, considering reliability implies that an engineer must be able to analyze how design decisions affect the incidence of failure. For instance, in order design reliable inte gritted circuits, it is necessary to analyze how decisions regarding design rules affect the yield, i.e., the percentage of functional chips obtained by the manufacturing process. Of equal importance in producing reliable computers is the detection of failures in its Very Large Scale Integrated (VLSI) circuit components, caused by errors in the design specification, implementation, or manufacturing processes. Design verification involves the checking of the specification of a design for correctness prior to carrying out an implementation. Implementation verification ensures that the manual design or automatic synthesis process is correct, i.e., the mask-level description correctly implements the specification. Manufacture test involves the checking of the complex fabrication process for correctness, i.e., ensuring that there are no manufacturing defects in the integrated circuit. It should be noted that all the above verification mechanisms deal not only with verifying the functionality of the integrated circuit but also its performance.

Book Description
Logic synthesis has become a fundamental component of the ASIC design flow, and Logic Synthesis Using Synopsys® has been written for all those who dislike reading manuals but who still like to learn logic synthesis as practised in the real world. The primary focus of the book is Synopsys Design Compiler®: the leading synthesis tool in the EDA marketplace. The book is specially organized to assist designers accustomed to schematic capture based design to develop the required expertise to effectively use the Compiler. Over 100 `classic scenarios' faced by designers using the Design Compiler have been captured and discussed, and solutions provided. The scenarios are based both on personal experiences and actual user queries. A general understanding of the problem-solving techniques provided will help the reader debug similar and more complicated problems. Furthermore, several examples and dc-shell scripts are provided. Specifically, Logic Synthesis Using Synopsys® will help the reader develop a better understanding of the synthesis design flow, optimization strategies using the Design Compiler, test insertion using the Test Compiler®, commonly used interface formats such as EDIF and SDF, and design re-use in a synthesis-based design methodology. Examples have been provided in both VHDL and Verilog. Audience: Written with CAD engineers in mind to enable them to formulate an effective synthesis-based ASIC design methodology. Will also assist design teams to better incorporate and effectively integrate synthesis with their existing in-house design methodology and CAD tools.

Book Description
The first edition of Principles of Verifiable RTL Design offered a common sense method for simplifying and unifying assertion specification by creating a set of predefined specification modules that could be instantiated within the designer's RTL. Since the release of the first edition, an entire industry-wide initiative for assertion specification has emerged based on ideas presented in the first edition. This initiative, known as the Open Verification Library Initiative (www.verificationlib.org), provides an assertion interface standard that enables the design engineer to capture many interesting properties of the design and precludes the need to introduce new HDL constructs (i.e., extensions to Verilog are not required). Furthermore, this standard enables the design engineer to `specify once,' then target the same RTL assertion specification over multiple verification processes, such as traditional simulation, semi-formal and formal verification tools. The Open Verification Library Initiative is an empowering technology that will benefit design and verification engineers while providing unity to the EDA community (e.g., providers of testbench generation tools, traditional simulators, commercial assertion checking support tools, symbolic simulation, and semi-formal and formal verification tools). The second edition of Principles of Verifiable RTL Design expands the discussion of assertion specification by including a new chapter entitled `Coverage, Events and Assertions'. All assertions exampled are aligned with the Open Verification Library Initiative proposed standard. Furthermore, the second edition provides expanded discussions on the following topics: start-up verification; the place for 4-state simulation; race conditions; RTL-style-synthesizable RTL (unambiguous mapping to gates); more `bad stuff'. The goal of the second edition is to keep the topic current. Principles of Verifiable RTL Design, A Functional Coding Style Supporting Verification Processes, Second Edition tells you how you can write Verilog to describe chip designs at the RTL level in a manner that cooperates with verification processes. This cooperation can return an order of magnitude improvement in performance and capacity from tools such as simulation and equivalence checkers. It reduces the labor costs of coverage and formal model checking by facilitating communication between the design engineer and the verification engineer. It also orients the RTL style to provide more useful results from the overall verification process.

Book Description
This volume contains a collection of papers presented at the NATO Advanced Study Institute on ·Testing and Diagnosis of VLSI and ULSI" held at Villa Olmo, Como (Italy) June 22 -July 3,1987. High Density technologies such as Very-Large Scale Integration (VLSI), Wafer Scale Integration (WSI) and the not-so-far promises of Ultra-Large Scale Integration (ULSI), have exasperated the problema associated with the testing and diagnosis of these devices and systema. Traditional techniques are fast becoming obsolete due to unique requirements such as limited controllability and observability, increasing execution complexity for test vector generation and high cost of fault simulation, to mention just a few. New approaches are imperative to achieve the highly sought goal of the • three months· turn around cycle time for a state-of-the-art computer chip. The importance of testing and diagnostic processes is of primary importance if costs must be kept at acceptable levels. The objective of this NATO-ASI was to present, analyze and discuss the various facets of testing and diagnosis with respect to both theory and practice. The contents of this volume reflect the diversity of approaches currently available to reduce test and diagnosis time. These approaches are described in a concise, yet clear way by renowned experts of the field. Their contributions are aimed at a wide readership: the uninitiated researcher will find the tutorial chapters very rewarding. The expert wiII be introduced to advanced techniques in a very comprehensive manner.
