An eBook reader can be a software application for use on a computer such as Microsoft's free Reader application, or a book-sized computer THE is used solely as a reading device such as Nuvomedia's Rocket eBook. Users can purchase an eBook on diskette or CD, but the most popular method of getting an eBook is to purchase a downloadable file of the eBook or other reading material from a Web site such as Barnes and Noble to be read from the user's computer or reading device.

Contents xiii 10 Over-the-Cell Routing and Via Minimization Contents xv This Page Intentionally Left Blank Foreword Since the invention of integrated circuits thirty years ago, manufacturing of electronic systems has taken rapid strides in improvement in speed, size, and cost.
A combination of high product performance and low per-unit cost leads to the very pervasive introduction of integrated circuit chips to many aspects of modern engineering and scientific endeavors including computations, telecommunications, aeronautics, genetics, bioengineering, manufacturing, factory automation, and so on. It is clear that the integrated circuit chip will play the role of a key building block in the information society of the twenty-first century.
The manufacture of integrated circuit chips is similar to the manufacture of other highly sophisticated engineering products in many ways. The three major steps are designing the product, fabricating the product, and testing the fabricated product.
In the design step, a large number of components are to be designed or selected, specifications on how these components should be as- sembled are to be made, and verification steps are to be carried out to assure the correctness of the design.
In the manufacturing step, a great deal of man- power, and a large collection of expensive equipment, together with painstaking care are needed to assemble the product according to the design specification. Finally, the fabricated product must be tested to check its physical function- ality. As in all engineering problems, there are conflicting requirements in all these steps. In the design step, we want to obtain an optimal product design, and yet we also want the design cycle to be short.
In the fabrication step, we want the product yield to be high, and yet we also need to be able to produce a large volume of the product and get them to market in time. In the testing step, we want the product to be tested thoroughly and yet we also want to be able to do so quickly. The title of this book reveals how the issue of enormous design complexity is to be handled so that high quality designs can be obtained in a reason- able amount of design time: We use muscles automation and we use brain Professor Sherwani has written an excellent book to introduce students in computer science and electrical engineering as well as CAD engi- neers to the subject of physical design of VLSI circuits.
Physical design is a key step in the design process. Research and development efforts in the last twenty years have led us to some very good understanding on many of the important problems in physical design.
All aspects of the physical design process are covered in a meticulous and comprehensive manner. The treatment is enlightening and enticing. A strong emphasis is placed on the algorithmic aspect of the design process. Algorithms are presented in an intuitive manner without the obscurity of unnecessary formalism. Both theoretical and practical aspects of algorithmic design are stressed.
Neither the elegance of optimal algorithms nor the usefulness of heuristic algorithms are overlooked. The many exercises included in the book are also most helpful teaching aids. This is a book on physical design algorithms. Yet, this is a book that goes beyond physical design algorithms.
There are other important design steps of which our understanding is still quite limited. Furthermore, develop- ment of new materials, devices, and technologies will unquestionably create new problems and new avenues of research and development in the design process.
An algorithmic outlook on design problem and the algorithmic techniques for solving complex design problems, which a reader learns through the examples drawn from physical design in this book, will transcend the confine of physical design and will undoubtedly prepare the reader for many of the activities in the field of computer-aided design of VLSI circuits. Urbana-Champaign, September C. Liu Of course, this tremendous growth in the area of VLSI design is made possible by the development of sophisticated design tools and software.
To deal with the complexity of millions of components and to achieve a turn around time of a couple of months, VLSI design tools must not only be computationally fast but also perform close to optimal.
In the last two decades, the research in physical design automation has been very intense, and literally thousands of research articles covering all phases of physical design automation have been published.
The development of VLSI physical design automation also depends on availability of trained manpower. We have two types of students studying VLSI physical design: students preparing for a research career and students preparing for a career in industry.
Both types of students need to build a solid background. However, currently we lack courses and text books which give students a comprehensive background.
It is common to find stu- dents doing research in placement, but are unaware of the latest developments in compaction. Those students seeking careers in industry will find that the VLSI physical design industry is very fast paced.
They are expected to be con- versant with existing tools and algorithms for all the stages of the design cycle of a VLSI chip. In industry, it is usual to find CAD engineers who work on one aspect of physical design and lack knowledge of other aspects. For example, a CAD engineer working in the development of detailed routers may not be knowledgeable about partitioning algorithms. This is again due to the lack of comprehensive textbooks which cover background material in all aspects of VLSI physical design.
Providing a comprehensive background in one textbook in VLSI physical design is indeed difficult. This is due to the fact that physical design automa- tion requires a mix of backgrounds. Some electrical engineering and a solid undergraduate computer science background is necessary to grasp the funda- mentals.
In addition, some background in graph theory and combinatorics is also needed, since many of the algorithms are graph theoretic or use other combinatorial optimization techniques. This mix of backgrounds has perhaps This book is an attempt to provide a comprehensive background in the principles and algorithms of VLSI physical design.
The goal of this book is to serve as a basis for the development of introductory level graduate courses in VLSI physical design automation. It is hoped that the book provides self con- tained material for teaching and learning algorithms of physical design.
All algorithms which are considered basic have been included. The algorithms are presented in an intuitive manner, so that the reader can concentrate on the basic idea of the algorithms. Yet, at the same time, enough detail is provided so that readers can actually implement the algorithms given in the text and use them.
Initially written as a set of class notes, the book took form as it was refined over a period of three years. Overview of the Book This book covers all aspects of physical design.
The first three chapters provide the background material, while the focus of each chapter of the rest of the book is on each phase of the physical design cycle. Topics include the VLSI design cycle, physical design cycle, design styles and packaging styles.
Algorithms for VLSI Physical Design Automation
It seems that you're in Germany. We have a dedicated site for Germany. It provides a comprehensive treatment of the principles and algorithms of VLSI physical design. Each chapter contains algorithms that are discussed in detail. Additional algorithms are presented in a somewhat shorter format. References to advanced algorithms are presented at the end of each chapter. The first three chapters provide the background material while the subsequent chapters focus on each phase of the physical design cycle.

Based on the very successful First Edition, it provides a comprehensive treatment of the principles and algorithms of VLSI physical design, presenting the concepts and algorithms in an intuitive manner. Each chapter contains algorithms that are discussed in detail. Additional algorithms are presented in a somewhat shorter format.
