In the past ten years there has been a revolution in the practice of hardware design. Professionals now rely on CAD software, rapid prototyping, and programmable logic devices to streamline the design process. Contemporary Logic Design is the first text to address these changes - and to offer a truly modern introduction to logic design. Throughout, the author complements his presentation of logic design theory with discussions of current design technologies. Approximately 60% of the book presents new material; the remainder has been re-organized and partially re-written to correspond to the organizational changes.  





Comprehensive coverage of programmable logic, including ROMs, PALs, and PLAs.


Introduction to a wide range of software tools (including schematic capture, logic simulation and Boolean minimization) - Demonstrates how they fit into the hardware design process.


Hands-on experimentation using software tools such as Aldec- Bolsters students' understanding of practical design methods.




New to this Edition



New introduction - Now introduces the concepts of computation, encoding, sequencing, and instruction interpretation.

- Sets a better road map to the rest of the book and provide a rationale for its organization.  

- Includes many more case studies to help students see the design process in action, rather than discussing the design process in the abstract.


Re-partitioning of material on combinational and sequential logic - the two major sections on combinational and sequential logic has been divided into a set of chapters.  They first cover fundamental concepts, then describe the principles of manipulating the logic into different forms, followed by a discussion of the optimizations and tools that are available, and conclude with the technologies available to build logic circuits.  

- Each  is capped by a set of comprehensive design case studies.


More Emphasis on Programmable Logic.  

- New material on the latest programmable logic technologies for realizing digital designs with a focus on the underlying concepts.


Hardware description languages - Given a more central role to reflect their total acceptance by the design community over the past 10 years.  

- Describes only the basics of one of the dominant languages (Verilog), discussing behavior as well as covering the basics of HDL simulation models.  

- Highlights the power of the languages in making designs more parameterizable and customizable and designers more efficient.


New design case studies - Provides a large collection of examples where the intuitions and rules-of-thumb are discussed explicitly.  

- Many new and extensive design case studies  found throughout the text and in two large chapters (5& 10) focus on combinational and sequential logic.


Offers computer organization materials compatible with the text on a website.

--The last two chapters of the previous edition on Datapath, Control and Register-Transfer are now available on the book's website.

Back Cover

In the decade since the first edition of this book was published, the technologies of digital design have continued to evolve. The evolution has run along two related tracks: the underlying physical technology and the software tools that facilitate the application of new devices. The trends identified in the first edition have continued and promise to continue to do so. Programmable logic is virtually the norm for digital designers and the art of digital design now requires the software skills to deal with hardware description languages.

Hardware designers now spend the majority of their time dealing with software. Specifically, the tools needed to efficiently map digital designs onto the emerging programmable devices that are growing more sophisticated. They capture their design specifications in software with language appropriate for describing the parallelism of hardware; they use software tools to simulate their designs and then to synthesize it into the implementation technology of choice. Design time is radically reduced, as market pressures require products to be introduced quickly at the right price and performance.

Although the complexity of designs is necessitating ever more powerful abstractions, the fundamentals remain unchanged. The contemporary digital designer must have a much broader understanding of the discipline of computation, including both hardware and software. This broader perspective is present in this second edition.


Randy Katz received his undergraduate degree from Cornell University, and his M.S. and Ph.D. degrees from the University of California, Berkeley. He joined the faculty at Berkeley in 1983, where he is now the United Microelectronics Corporation Distinguished Professor in Electrical Engineering and Computer Science. He is a Fellow of the ACM and the IEEE, and a member of the National Academy of Engineering and the American Academy of Arts and Sciences. He has published over 230 refereed technical papers, book chapters, and books. He has won numerous awards, including 12 best paper awards, one "test of time" paper award, three best presentation awards, the Outstanding Alumni Award of the Computer Science Division, the CRA Outstanding Service Award, the Berkeley Distinguished Teaching Award, the Air Force Exceptional Civilian Service Decoration, The IEEE Reynolds Johnson Information Storage Award, the ASEE Frederic E. Terman Award, and the ACM Karl V. Karlstrom Outstanding Educator Award. With colleagues at Berkeley, he developed the terminology of and early prototypes for Redundant Arrays of Inexpensive Disks (RAID;. While on leave for government service in 1993-1994, he established and connected the White House to the Internet.

Gaetano Borriello is a Professor of Computer Science & Engineering at the University of Washington in Seattle. He received his undergraduate degree from the Polytechnic University, his M.S. degree from Stanford University, and his Ph.D. degree from the University of California, Berkeley. Prior to Berkeley he was a member of the research staff at Xerox's Palo Alto Research Center, where he was one of the designers of the first single-chip integrated Ethernet controller. He joined the faculty at UW in 1988 and received a Distinguished Teaching Award for his contributions in establishing the Computer Engineering undergraduate degree program. His research interests are in the design of ubiquitous computing technologies, the design of the embedded systems that connect the physical and virtual worlds, in the use of wireless sensors to infer human activities, and in creating applications that automatically adapt to their user's context. He is the founding director of Intel Research Seattle, a research laboratory focusing on new technologies and usage models for ubiquitous computing.
