This book was released on 1998-10-31 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent years have seen rapid strides in the level of sophistication of VLSI circuits. On the performance front, there is a vital need for techniques to design fast, low-power chips with minimum area for increasingly complex systems, while on the economic side there is the vastly increased pressure of time-to-market. These pressures have made the use of CAD tools mandatory in designing complex systems. Timing Analysis and Optimization of Sequential Circuits describes CAD algorithms for analyzing and optimizing the timing behavior of sequential circuits with special reference to performance parameters such as power and area. A unified approach to performance analysis and optimization of sequential circuits is presented. The state of the art in timing analysis and optimization techniques is described for circuits using edge-triggered or level-sensitive memory elements. Specific emphasis is placed on two methods that are true sequential timing optimizations techniques: retiming and clock skew optimization. Timing Analysis and Optimization of Sequential Circuits covers the following topics: Algorithms for sequential timing analysis Fast algorithms for clock skew optimization and their applications Efficient techniques for retiming large sequential circuits Coupling sequential and combinational optimizations. Timing Analysis and Optimization of Sequential Circuits is written for graduate students, researchers and professionals in the area of CAD for VLSI and VLSI circuit design.

Download or read book Asynchronous Circuit Design for VLSI Signal Processing written by Teresa H. Meng and published by Springer Science & Business Media. This book was released on 2011-06-27 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Asynchronous Circuit Design for VLSI Signal Processing is a collection of research papers on recent advances in the area of specification, design and analysis of asynchronous circuits and systems. This interest in designing digital computing systems without a global clock is prompted by the ever growing difficulty in adopting global synchronization as the only efficient means to system timing. Asynchronous circuits and systems have long held interest for circuit designers and researchers alike because of the inherent challenge involved in designing these circuits, as well as developing design techniques for them. The frontier research in this area can be traced back to Huffman's publications `The Synthesis of Sequential Switching Circuits' in 1954 followed by Unger's book, `Asynchronous Sequential Switching Circuits' in 1969 where a theoretical foundation for handling logic hazards was established. In the last few years a growing number of researchers have joined force in unveiling the mystery of designing correct asynchronous circuits, and better yet, have produced several alternatives in automatic synthesis and verification of such circuits. This collection of research papers represents a balanced view of current research efforts in the design, synthesis and verification of asynchronous systems.

This book was released on 2012-12-06 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapid increases in chip complexity, increasingly faster clocks, and the proliferation of portable devices have combined to make power dissipation an important design parameter. The power consumption of a digital system determines its heat dissipation as well as battery life. For some systems, power has become the most critical design constraint. Computer-Aided Design Techniques for Low Power Sequential Logic Circuits presents a methodology for low power design. The authors first present a survey of techniques for estimating the average power dissipation of a logic circuit. At the logic level, power dissipation is directly related to average switching activity. A symbolic simulation method that accurately computes the average switching activity in logic circuits is then described. This method is extended to handle sequential logic circuits by modeling correlation in time and by calculating the probabilities of present state lines. Computer-Aided Design Techniques for Low Power Sequential Logic Circuits then presents a survey of methods to optimize logic circuits for low power dissipation which target reduced switching activity. A method to retime a sequential logic circuit where registers are repositioned such that the overall glitching in the circuit is minimized is also described. The authors then detail a powerful optimization method that is based on selectively precomputing the output logic values of a circuit one clock cycle before they are required, and using the precomputed value to reduce internal switching activity in the succeeding clock cycle. Presented next is a survey of methods that reduce switching activity in circuits described at the register-transfer and behavioral levels. Also described is a scheduling algorithm that reduces power dissipation by maximising the inactivity period of the modules in a given circuit. Computer-Aided Design Techniques for Low Power Sequential Logic Circuits concludes with a summary and directions for future research.

Available in PDF, EPUB and Kindle. Book excerpt: Computer-aided design of VLSI circuits is usually carried out in three synthesis steps: high-level synthesis, logic synthesis and layout synthesis. Each synthesis step is further broken into a few optimization problems. In this thesis we study several such problems in logic and layout synthesis. We study how the technique of retiming can be introduced to enhance the solution of three problems in logic synthesis. Specifically, we consider a partial scan approach to the problem of design-for-testability in which a set of scan signals (instead of scan flip-flops) is pre-selected. We propose an algorithm that uses retiming to position flip-flops on the pre-selected scan signals so that these signals can be scanned. Next, we combine resynthesis with retiming to reduce the cycle time of a sequential circuit. We also integrate retiming into the technology mapping step for look-up table based field programmable gate arrays (FPGAs). We present an optimal cycle time technology mapping algorithm for sequential circuits. In layout synthesis, we study the area minimization problem in floorplanning (also known as the floorplan sizing problem). We propose two area minimization algorithms for general floorplans. Both algorithms can be viewed as generalizations of the classical area minimization algorithm by Otten and Stockmeyer. A fast pseudo-polynomial area minimization algorithm for an important class of hierarchical floorplans is also proposed. We settle an open problem on the complexity of the area minimization problem for hierarchical floorplans by showing it to be NP-complete. Finally, we study a graph constraint reduction problem in symbolic layout compaction. We present a polynomial algorithm that achieves optimal reduction.

Download or read book Sequential Logic written by Joseph Cavanagh and published by CRC Press. This book was released on 2006-06-02 with total page 913 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until now, there was no single resource for actual digital system design. Using both basic and advanced concepts, Sequential Logic: Analysis and Synthesis offers a thorough exposition of the analysis and synthesis of both synchronous and asynchronous sequential machines. With 25 years of experience in designing computing equipment, the author stresses the practical design of state machines. He clearly delineates each step of the structured and rigorous design principles that can be applied to practical applications. The book begins by reviewing the analysis of combinatorial logic and Boolean algebra, and goes on to define sequential machines and discuss traditional and alternative methods for synthesizing synchronous sequential machines. The final chapters deal with asynchronous sequential machines and pulse-mode asynchronous sequential machines. Because this volume is technology-independent, these techniques can be used in a variety of fields, such as electrical and computer engineering as well as nanotechnology. By presenting each method in detail, expounding on several corresponding examples, and providing over 500 useful figures, Sequential Logic is an excellent tutorial on analysis and synthesis procedures.
