History of the Book The last three decades have witnessed an explosive development in integrated circuit fabrication technologies. The complexities of cur rent CMOS circuits are reaching beyond the 100 nanometer feature size and multi-hundred million transistors per integrated circuit. To fully exploit this technological potential, circuit designers use sophisticated Computer-Aided Design (CAD) tools. While supporting the talents of innumerable microelectronics engineers, these CAD tools have become the enabling factor responsible for the successful design and implemen tation of thousands of high performance, large scale integrated circuits. This research monograph originated from a body of doctoral disserta tion research completed by the first author at the University of Rochester from 1994 to 1999 while under the supervision of Prof. Eby G. Friedman. This research focuses on issues in the design of the clock distribution net work in large scale, high performance digital synchronous circuits and particularly, on algorithms for non-zero clock skew scheduling. During the development of this research, it has become clear that incorporating timing issues into the successful integrated circuit design process is of fundamental importance, particularly in that advanced theoretical de velopments in this area have been slow to reach the designers' desktops.

Networks are pervasive. Very large scale integrated (VLSI) systems are no different, consisting of dozens of interconnected subsystems, hundreds of modules, and many billions of transistors and wires. Graph theory is crucial for managing and analyzing these systems. In this book, VLSI system design is discussed from the perspective of graph theory. Starting from theoretical foundations, the authors uncover the link connecting pure mathematics with practical product development. This book not only provides a review of established graph theoretic practices, but also discusses the latest advancements in graph theory driving modern VLSI technologies, covering a wide range of design issues such as synchronization, power network models and analysis, and interconnect routing and synthesis. Provides a practical introduction to graph theory in the context of VLSI systems engineering; Reviews comprehensively graph theoretic methods and algorithms commonly used during VLSI product development process; Includes a review of novel graph theoretic methods and algorithms for VLSI system design.

Statistical timing analysis is an area of growing importance in nanometer te- nologies‚ as the uncertainties associated with process and environmental var- tions increase‚ and this chapter has captured some of the major efforts in this area. This remains a very active field of research‚ and there is likely to be a great deal of new research to be found in conferences and journals after this book is published. In addition to the statistical analysis of combinational circuits‚ a good deal of work has been carried out in analyzing the effect of variations on clock skew. Although we will not treat this subject in this book‚ the reader is referred to [LNPS00‚ HN01‚ JH01‚ ABZ03a] for details. 7 TIMING ANALYSIS FOR SEQUENTIAL CIRCUITS 7.1 INTRODUCTION A general sequential circuit is a network of computational nodes (gates) and memory elements (registers). The computational nodes may be conceptualized as being clustered together in an acyclic network of gates that forms a c- binational logic circuit. A cyclic path in the direction of signal propagation 1 is permitted in the sequential circuit only if it contains at least one register . In general, it is possible to represent any sequential circuit in terms of the schematic shown in Figure 7.1, which has I inputs, O outputs and M registers. The registers outputs feed into the combinational logic which, in turn, feeds the register inputs. Thus, the combinational logic has I + M inputs and O + M outputs.

This book describes methods for distributing power in high speed, high complexity integrated circuits with power levels exceeding many tens of watts and power supplies below a volt. It provides a broad and cohesive treatment of power distribution systems and related design problems, including both circuit network models and design techniques for on-chip decoupling capacitors, providing insight and intuition into the behavior and design of on-chip power distribution systems. Organized into subareas to provide a more intuitive flow to the reader, this second edition adds more than a hundred pages of new content, including inductance models for interdigitated structures, design strategies for multi-layer power grids, advanced methods for efficient power grid design and analysis, and methodologies for simultaneously placing on-chip multiple power supplies and decoupling capacitors. The emphasis of this additional material is on managing the complexity of on-chip power distribution networks.

This research monograph deals with the design and analysis of integrated circuits, and describes how on-chip inductance can have a tangible effect on high speed integrated circuits. Ismail (Northwestern University) and Friedman (University of Rochester) review basic transmission line theory, methods for evaluating the transient response of linear networks, and characterization of MOS transistors. They then introduce a closed form solution for the propagation delay of a CMOS gate driving a lossy transmission line with a terminating CMOS gate. Further discussion includes waveform characterization of signals at different nodes of an RLC tree, dynamic and short-circuit power of CMOS gates driving lossless transmission lines, and the direct truncation of the transfer function (DTT) method for evaluation of the transient response in RLC circuits. c.

According to the Semiconductor Industry Association's 1999 International Technology Roadmap for Semiconductors, by the year 2008 the integration of more than 500 million transistors will be possible on a single chip. Integrating transistors on silicon will depend increasingly on design reuse. Design reuse techniques have become the subject of books, conferences, and podium discussions over the last few years. However, most discussions focus on higher-level abstraction like RTL descriptions, which can be synthesized. Design reuse is often seen as an add-on to normal design activity, or a special design task that is not an integrated part of the existing design flow. This may all be true for the ASIC world, but not for high-speed, high-performance microprocessors. In the field of high-speed microprocessors, design reuse is an integrated part of the design flow. The method of choice in this demanding field was, and is always, physical design reuse at the layout level. In the past, the practical implementations of this method were linear shrinks and the lambda approach. With the scaling of process technology down to 0.18 micron and below, this approach lost steam and became inefficient. The only viable solution is a method, which is now called Automatic Layout Modification (ALM). It combines compaction, mask manipulation, and correction with powerful capabilities. Automatic Layout Modification, Including design reuse of the Alpha CPU in 0.13 micron SOI technology is a welcome effort to improving some of the practices in chip design today. It is a comprehensive reference work on Automatic Layout Modification which will be valuable to VLSI courses at universities, and to CAD and circuit engineers and engineering managers.
