Making VHDL a simple and easy-to-use hardware description language Many engineers encountering VHDL (very high speed integrated circuits hardware description language) for the first time can feel overwhelmed by it. This book bridges the gap between the VHDL language and the hardware that results from logic synthesis with clear organisation, progressing from the basics of combinational logic, types, and operators; through special structures such as tristate buses, register banks and memories, to advanced themes such as developing your own packages, writing test benches and using the full range of synthesis types. This third edition has been substantially rewritten to include the new VHDL-2008 features that enable synthesis of fixed-point and floating-point hardware. Extensively updated throughout to reflect modern logic synthesis usage, it also contains a complete case study to demonstrate the updated features. Features to this edition include: a common VHDL subset which will work across a range of different synthesis systems, targeting a very wide range of technologies a design style that results in long design lifetimes, maximum design reuse and easy technology retargeting a new chapter on a large scale design example based on a digital filter from design objective and design process, to testing strategy and test benches a chapter on writing test benches, with everything needed to implement a test-based design strategy extensive coverage of data path design, including integer, fixed-point and floating-point arithmetic, logic circuits, shifters, tristate buses, RAMs, ROMs, state machines, and decoders Focused specifically on logic synthesis, this book is for professional hardware engineers using VHDL for logic synthesis, and digital systems designers new to VHDL but familiar with digital systems. It offers all the knowledge and tools needed to use VHDL for logic synthesis. Organised in themed chapters and with a comprehensive index, this complete reference will also benefit postgraduate students following courses on microelectronics or VLSI/ semiconductors and digital design.

This book is structured in a practical, example-driven, manner. The use of VHDL for constructing logic synthesisers is one of the aims of the book; the second is the application of the tools to the design process. Worked examples, questions and answers are provided together with do and don'ts of good practice. An appendix on logic design the source code are available free of charge over the Internet.

This is the first book to detail the use of VHDL with logic synthesis techniques, showing how to use the hardware description language to achieve SLSI design results. It explains VHDL features in terms of the hardware mappings performed in synthesis basics, then builds to more advanced topics, like the writing of VHDL packages and the writing of effective text benches.

This book provides the most up-to-date coverage using the Synopsys program in the design of integrated circuits. The incorporation of "synthesis tools" is the most popular new method of designing integrated circuits for higher speeds covering smaller surface areas.Synopsys is the dominant computer-aided circuit design program in the world. All of the major circuit manufacturers and ASIC design firms use Synopsys. In addition, Synopsys is used in teaching and laboratories at over 600 universities. - First practical guide to using synthesis with Synopsys - Synopsys is the #1 design program for IC design

A Designer's Guide to VHDL Synthesis is intended for both design engineers who want to use VHDL-based logic synthesis ASICs and for managers who need to gain a practical understanding of the issues involved in using this technology. The emphasis is placed more on practical applications of VHDL and synthesis based on actual experiences, rather than on a more theoretical approach to the language. VHDL and logic synthesis tools provide very powerful capabilities for ASIC design, but are also very complex and represent a radical departure from traditional design methods. This situation has made it difficult to get started in using this technology for both designers and management, since a major learning effort and `culture' change is required. A Designer's Guide to VHDL Synthesis has been written to help design engineers and other professionals successfully make the transition to a design methodology based on VHDL and log synthesis instead of the more traditional schematic based approach. While there are a number of texts on the VHDL language and its use in simulation, little has been written from a designer's viewpoint on how to use VHDL and logic synthesis to design real ASIC systems. The material in this book is based on experience gained in successfully using these techniques for ASIC design and relies heavily on realistic examples to demonstrate the principles involved.

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.

This book describes RTL design, synthesis, and timing closure strategies for SOC blocks. It covers high-level RTL design scenarios and challenges for SOC design. The book gives practical information on the issues in SOC and ASIC prototyping using modern high-density FPGAs. The book covers SOC performance improvement techniques, testing, and system-level verification. The book also describes the modern Xilinx FPGA architecture and their use in SOC prototyping. The book covers the Synopsys DC, PT commands, and use of them to constraint and to optimize SOC design. The contents of this book will be of use to students, professionals, and hobbyists alike.

A completely updated and expanded comprehensive treatment of VHDL and its applications to the design and simulation of real, industry-standard circuits. This comprehensive treatment of VHDL and its applications to the design and simulation of real, industry-standard circuits has been completely updated and expanded for the third edition. New features include all VHDL-2008 constructs, an extensive review of digital circuits, RTL analysis, and an unequaled collection of VHDL examples and exercises. The book focuses on the use of VHDL rather than solely on the language, with an emphasis on design examples and laboratory exercises. The third edition begins with a detailed review of digital circuits (combinatorial, sequential, state machines, and FPGAs), thus providing a self-contained single reference for the teaching of digital circuit design with VHDL. In its coverage of VHDL-2008, it makes a clear distinction between VHDL for synthesis and VHDL for simulation. The text offers complete VHDL codes in examples as well as simulation results and comments. The significantly expanded examples and exercises include many not previously published, with multiple physical demonstrations meant to inspire and motivate students. The book is suitable for undergraduate and graduate students in VHDL and digital circuit design, and can be used as a professional reference for VHDL practitioners. It can also serve as a text for digital VLSI in-house or academic courses.
