Logic Synthesis for Field-Programmable Gate Arrays (The Springer International Series in Engineering and Computer Science #324)

by Rajeev Murgai Robert K. Brayton Alberto L. Sangiovanni-Vincentelli

Short turnaround has become critical in the design of electronic systems. Software- programmable components such as microprocessors and digital signal processors have been used extensively in such systems since they allow rapid design revisions. However, the inherent performance limitations of software-programmable systems mean that they are inadequate for high-performance designs. Designers thus turned to gate arrays as a solution. User-programmable gate arrays (field-programmable gate arrays, FPGAs) have recently emerged and are changing the way electronic systems are designed and implemented. The growing complexity of the logic circuits that can be packed onto an FPGA chip means that it has become important to have automatic synthesis tools that implement logic functions on these architectures. Logic Synthesis for Field-Programmable Gate Arrays describes logic synthesis for both look-up table (LUT) and multiplexor-based architectures, with a balanced presentation of existing techniques together with algorithms and the system developed by the authors. Audience: A useful reference for VLSI designers, developers of computer-aided design tools, and anyone involved in or with FPGAs.

Logic Synthesis for Finite State Machines Based on Linear Chains of States: Foundations, Recent Developments and Challenges (Studies in Systems, Decision and Control #113)

by Alexander Barkalov Larysa Titarenko Jacek Bieganowski

This book discusses Moore finite state machines (FSMs) implemented with field programmable gate arrays (FPGAs) including look-up table (LUT) elements and embedded memory blocks (EMBs). To minimize the number of LUTs in FSM logic circuits, the authors propose replacing a state register with a state counter. They also put forward an approach allowing linear chains of states to be created, which simplifies the system of input memory functions and, therefore, decreases the number of LUTs in the resulting FSM circuit. The authors combine this approach with using EMBs to implement the system of output functions (microoperations). This allows a significant decrease in the number of LUTs, as well as eliminating a lot of interconnections in the FSM logic circuit. As a rule, it also reduces the area occupied by the circuit and diminishes the resulting power dissipation.This book is an interesting and valuable resource for students and postgraduates in the area of computer science, as well as for designers of digital systems that included complex control units

Logic Synthesis for FPGA-Based Control Units: Structural Decomposition in Logic Design (Lecture Notes in Electrical Engineering #636)

by Alexander Barkalov Larysa Titarenko Kamil Mielcarek Sławomir Chmielewski

This book focuses on control units, which are a vital part of modern digital systems, and responsible for the efficiency of controlled systems. The model of a finite state machine (FSM) is often used to represent the behavior of a control unit. As a rule, control units have irregular structures that make it impossible to design their logic circuits using the standard library cells. Design methods depend strongly on such factors as the FSM used, specific features of the logic elements implemented in the FSM logic circuit, and the characteristics of the control algorithm to be interpreted.This book discusses Moore and Mealy FSMs implemented with FPGA chips, including look-up table elements (LUT) and embedded memory blocks (EMB). It is crucial to minimize the number of LUTs and EMBs in an FSM logic circuit, as well as to make the interconnections between the logic elements more regular, and various methods of structural decompositions can be used to solve this problem. These methods are reduced to the presentation of an FSM circuit as a composition of different logic blocks, the majority of which implement systems of intermediate logic functions different (and much simpler) than input memory functions and FSM output functions. The structural decomposition results in multilevel FSM circuits having fewer logic elements than equivalent single-level circuits. The book describes well-known methods of structural decomposition and proposes new ones, examining their impact on the final amount of hardware in an FSM circuit. It is of interest to students and postgraduates in the area of Computer Science, as well as experts involved in designing digital systems with complex control units. The proposed models and design methods open new possibilities for creating logic circuits of control units with an optimal amount of hardware and regular interconnections.

Logic Synthesis for VLSI-Based Combined Finite State Machines: Synthesis Targeting ASICs, CPLDs and FPGAs (Lecture Notes in Electrical Engineering #922)

by Alexander Barkalov Larysa Titarenko Kamil Mielcarek Małgorzata Mazurkiewicz Elżbieta Kawecka

The book is devoted to design and optimization of control units represented by combined finite state machines (CFSMs). The CFSMs combine features of both Mealy and Moore FSMs. Having states of Moore FSM, they produce output signals of both Mealy and Moore types. To optimize the circuits of CFSMs, we propose to use optimization methods targeting both Mealy and Moore FSMs. The book contains some original synthesis and optimization methods targeting hardware reduction in VLSI-based CFSM circuits. These methods take into account the peculiarities of both a CFSM model and a VLSI chip in use. The optimization is achieved due to combining classical optimization methods with new methods proposed in this book. These new methods are a mixed encoding of collections of microoperations and a twofold state assignment in CFSMs. All proposed methods target reducing the numbers of arguments in systems of Boolean functions representing CFSM circuits. Also, we propose to use classes of pseudoequivalent states of Moore FSMs to reduce the number of product terms in these systems.The book includes a lot of examples which contributes to a better understanding of the features of the synthesis methods under consideration. This is the first book entirely devoted to the problems associated with synthesis and optimization of VLSI-based CFSMs. We hope that the book will be interesting and useful for students and PhD students in the area of Computer Science, as well as for designers of various digital systems. We think that proposed CFSM models enlarge the class of models applied for implementation of control units with modern VLSI chips.

Logic Synthesis Using Synopsys®, Second Edition is for anyone who hates reading manuals but would still like to learn logic synthesis as practised in the real world. Synopsys Design Compiler, the leading synthesis tool in the EDA marketplace, is the primary focus of the book. The contents of this book are specially organized to assist designers accustomed to schematic capture-based design to develop the required expertise to effectively use the Synopsys Design Compiler. Over 100 `Classic Scenarios' faced by designers when using the Design Compiler have been captured, discussed and solutions provided. These scenarios are based on both personal experiences and actual user queries. A general understanding of the problem-solving techniques provided should help the reader debug similar and more complicated problems. In addition, several examples and dc_shell scripts (Design Compiler scripts) have also been provided. Logic Synthesis Using Synopsys®, Second Edition is an updated and revised version of the very successful first edition. The second edition covers several new and emerging areas, in addition to improvements in the presentation and contents in all chapters from the first edition. With the rapid shrinking of process geometries it is becoming increasingly important that `physical' phenomenon like clusters and wire loads be considered during the synthesis phase. The increasing demand for FPGAs has warranted a greater focus on FPGA synthesis tools and methodology. Finally, behavioral synthesis, the move to designing at a higher level of abstraction than RTL, is fast becoming a reality. These factors have resulted in the inclusion of separate chapters in the second edition to cover Links to Layout, FPGA Synthesis and Behavioral Synthesis, respectively. Logic Synthesis Using Synopsys®, Second Edition has been written with the CAD engineer in mind. A clear understanding of the synthesis tool concepts, its capabilities and the related CAD issues will help the CAD engineer formulate an effective synthesis-based ASIC design methodology. The intent is also to assist design teams to better incorporate and effectively integrate synthesis with their existing in-house design methodology and CAD tools.

Logical Analysis of Hybrid Systems: Proving Theorems for Complex Dynamics

by André Platzer

Hybrid systems are models for complex physical systems and have become a widely used concept for understanding their behavior. Many applications are safety-critical, including car, railway, and air traffic control, robotics, physical–chemical process control, and biomedical devices. Hybrid systems analysis studies how we can build computerized controllers for physical systems which are guaranteed to meet their design goals. The author gives a unique, logic-based perspective on hybrid systems analysis. It is the first book that leverages the power of logic for hybrid systems. The author develops a coherent logical approach for systematic hybrid systems analysis, covering its theory, practice, and applications. It is further shown how the developed verification techniques can be used to study air traffic and railway control systems. This book is intended for researchers, postgraduates, and professionals who are interested in hybrid systems analysis, cyberphysical or embedded systems design, logic and theorem proving, or transportation and automation.

Logical Foundations for Cognitive Agents: Contributions in Honor of Ray Reiter (Artificial Intelligence)

by Hector J. Levesque Fiora Pirri

It is a pleasure and an honor to be able to present this collection of papers to Ray Reiter on the occasion of his 60th birthday. To say that Ray's research has had a deep impact on the field of Artificial Intel­ ligence is a considerable understatement. Better to say that anyone thinking of do­ ing work in areas like deductive databases, default reasoning, diagnosis, reasoning about action, and others should realize that they are likely to end up proving corol­ laries to Ray's theorems. Sometimes studying related work makes us think harder about the way we approach a problem; studying Ray's work is as likely to make us want to drop our way of doing things and take up his. This is because more than a mere visionary, Ray has always been a true leader. He shows us how to proceed not by pointing from his armchair, but by blazing a trail himself, setting up camp, and waiting for the rest of us to arrive. The International Joint Conference on Ar­ tificial Intelligence clearly recognized this and awarded Ray its highest honor, the Research Excellence award in 1993, before it had even finished acknowledging all the founders of the field. The papers collected here sample from many of the areas where Ray has done pi­ oneering work. One of his earliest areas of application was databases, and this is re­ flected in the chapters by Bertossi et at. and the survey chapter by Minker.

Logical Foundations for Rule-Based Systems (Studies in Computational Intelligence #11)

by Antoni Ligeza

Thinking in terms of facts and rules is perhaps one of the most common ways of approaching problem de?nition and problem solving both in everyday life and under more formal circumstances. The best known set of rules, the Ten Commandments have been accompanying us since the times of Moses; the Decalogue proved to be simple but powerful, concise and universal. It is logically consistent and complete. There are also many other attempts to impose rule-based regulations in almost all areas of life, including professional work, education, medical services, taxes, etc. Some most typical examples may include various codes (e.g. legal or tra?c code), regulations (especially military ones), and many systems of customary or informal rules. The universal nature of rule-based formulation of behavior or inference principles follows from the concept of rules being a simple and intuitive yet powerful concept of very high expressive power. Moreover, rules as such encode in fact functional aspects of behavior and can be used for modeling numerous phenomena.

Logical Foundations of Cyber-Physical Systems

by André Platzer

Cyber-physical systems (CPSs) combine cyber capabilities, such as computation or communication, with physical capabilities, such as motion or other physical processes. Cars, aircraft, and robots are prime examples, because they move physically in space in a way that is determined by discrete computerized control algorithms. Designing these algorithms is challenging due to their tight coupling with physical behavior, while it is vital that these algorithms be correct because we rely on them for safety-critical tasks. This textbook teaches undergraduate students the core principles behind CPSs. It shows them how to develop models and controls; identify safety specifications and critical properties; reason rigorously about CPS models; leverage multi-dynamical systems compositionality to tame CPS complexity; identify required control constraints; verify CPS models of appropriate scale in logic; and develop an intuition for operational effects. The book is supported with homework exercises, lecture videos, and slides.

Logischer Entwurf digitaler Systeme (Hochschultext)

by Wolfgang Giloi Hans Liebig

Bücher über die Arbeitsweise und den Entwurf logischer oder digitaler Systeme weisen unserer Meinung nach häufig einen Schönheitsfehler auf (manche mehr, manche weniger): sie trennen zu wenig die Betrachtung des funktionellen Ver­ haltens solcher Systeme von der Betrachtung ihres tee h n i sc he n Verhaltens. Das Standardbuch über Digitaltechnik enthält in der Regel die Definition einer Schalt­ algebra sowie Methoden der Beschreibung und Minimierung von Schaltnetzen und Schaltwerken, aber zum Beispiel auch die Darlegung der Arbeitsweise von Dioden und Transistoren als logische Verknüpfungselemente, den Aufbau und die Arbeitsweise von Ferritkern-Speichern, und wenn es modern ist, wird es auch die schaltungs mäßige Realisierung von integrierten Verknüpfungselementen behandeln. Wir wollen hierdurch keineswegs ausdrücken, daß die Fragen des technischen Auf­ baus von logischen Systemen nicht sehr wichtig sind und einer theoretischen Durch­ dringung wie einer Anleitung zum praktischen Handeln bedürfen. Diese Fragen je­ doch zum Bestandteil eines Lehrbuchs zu machen, birgt bei dem atemberaubenden Tempo der technischen Entwicklung ständig die Gefahr in sich, daß ihre Darstellung bereits in dem Augenblick veraltet ist, in dem das Buch im Druck erscheint. Die aktuellsten Informationen auf diesem Gebiet sind zwangsläufig die Handbücher der Schal tkrei s -Hersteller.
