Logic-timing Simulation and the Degradation Delay Model PDF Author: Manuel J. Bellido
Publisher: Imperial College Press
ISBN: 1860945899
Category : Technology & Engineering
Languages : en
Pages : 288

Book Description
This book provides the reader with an extensive background in the field of logic-timing simulation and delay modeling. It includes detailed information on the challenges of logic-timing simulation, applications, advantages and drawbacks. The capabilities of logic-timing are explored using the latest research results that are brought together from previously disseminated materials. An important part of the book is devoted to the description of the ?Degradation Delay Model?, developed by the authors, showing how the inclusion of dynamic effects in the modeling of delays greatly improves the application cases and accuracy of logic-timing simulation. These ideas are supported by simulation results extracted from a wide range of practical applications.Sample Chapter(s)

Book Description
As digital integrated circuit size and complexity increases, the need for accurate and efficient computer simulation increases. Logic simulators such as SALOGS (SAndia LOGic Simulator), which utilize transition states in addition to the normal stable states, provide more accurate analysis than is possible with traditional logic simulators. Furthermore, the computational complexity of this analysis is far lower than that of circuit simulation such as SPICE. An eight-value logic simulation environment allows the use of accurate delay models that incorporate both element response and transition times. Thus, timing simulation with an accuracy approaching that of circuit simulation can be accomplished with an efficiency comparable to that of logic simulation. 4 figures.

Delay Modeling of Bipolar ECL/EFL (Emitter-Coupled Logic/Emitter-Follower-Logic) Circuits

Delay Modeling of Bipolar ECL/EFL (Emitter-Coupled Logic/Emitter-Follower-Logic) Circuits PDF Author: Andrew T. Yang
Publisher:
ISBN:
Category :
Languages : en
Pages : 79

Book Description
This report deals with the development of a delay-time model for timing simulation of large circuits consisting of Bipolar ECL(Emitter-Coupled Logic) and EFL (Emitter-Follower-Logic) networks. This model can provide adequate information on the performance of the circuits with a minimum expenditure of computation time. This goal is achieved by the use of proper circuit transient models on which analytical delay expressions can be derived with accurate results. The delay-model developed in this report is general enough to handle complex digital circuits with multiple inputs or/and multiple levels. The important effects of input slew rate are also included in the model. (Author).

Incremental Zero/ Unit-delay Switch-level Logic Simulation

Incremental Zero/ Unit-delay Switch-level Logic Simulation PDF Author: Larry G. Jones

ISBN:
Category : Computer simulation
Languages : en
Pages : 34

Book Description
Abstract: "We present the methods used in the implementation of an incremental zero/unit-delay switch-level logic simulator for MOS circuits based on the MOSSIM II switch-level model. The incremental simulator is embedded within a single fully-integrated capture/compile/simulate tool. Modifications to the design at any level in the structural design hierarchy are automatically mapped into changes in the underlying transistor netlist and the incremental simulator is triggered to quickly resimulate only those regions of the circuit whose behavior has been modified by the change."

Integrated Circuit Design. Power and Timing Modeling, Optimization and Simulation

Integrated Circuit Design. Power and Timing Modeling, Optimization and Simulation PDF Author: Bertrand Hochet
Publisher: Springer
ISBN: 354045716X
Category : Technology & Engineering
Languages : en
Pages : 510

Book Description
The International Workshop on Power and Timing Modeling, Optimization, and Simulation PATMOS 2002, was the 12th in a series of international workshops 1 previously held in several places in Europe. PATMOS has over the years evolved into a well-established and outstanding series of open European events on power and timing aspects of integrated circuit design. The increased interest, espe- ally in low-power design, has added further momentum to the interest in this workshop. Despite its growth, the workshop can still be considered as a very - cused conference, featuring high-level scienti?c presentations together with open discussions in a free and easy environment. This year, the workshop has been opened to both regular papers and poster presentations. The increasing number of worldwide high-quality submissions is a measure of the global interest of the international scienti?c community in the topics covered by PATMOS. The objective of this workshop is to provide a forum to discuss and inves- gate the emerging problems in the design methodologies and CAD-tools for the new generation of IC technologies. A major emphasis of the technical program is on speed and low-power aspects with particular regard to modeling, char- terization, design, and architectures. The technical program of PATMOS 2002 included nine sessions dedicated to most important and current topics on power and timing modeling, optimization, and simulation. The three invited talks try to give a global overview of the issues in low-power and/or high-performance circuit design.

Digital Timing Macromodeling for VLSI Design Verification

Digital Timing Macromodeling for VLSI Design Verification PDF Author: Jeong-Taek Kong
Publisher: Springer Science & Business Media
ISBN: 1461523214
Category : Technology & Engineering
Languages : en
Pages : 276

Book Description
Digital Timing Macromodeling for VLSI Design Verification first of all provides an extensive history of the development of simulation techniques. It presents detailed discussion of the various techniques implemented in circuit, timing, fast-timing, switch-level timing, switch-level, and gate-level simulation. It also discusses mixed-mode simulation and interconnection analysis methods. The review in Chapter 2 gives an understanding of the advantages and disadvantages of the many techniques applied in modern digital macromodels. The book also presents a wide variety of techniques for performing nonlinear macromodeling of digital MOS subcircuits which address a large number of shortcomings in existing digital MOS macromodels. Specifically, the techniques address the device model detail, transistor coupling capacitance, effective channel length modulation, series transistor reduction, effective transconductance, input terminal dependence, gate parasitic capacitance, the body effect, the impact of parasitic RC-interconnects, and the effect of transmission gates. The techniques address major sources of errors in existing macromodeling techniques, which must be addressed if macromodeling is to be accepted in commercial CAD tools by chip designers. The techniques presented in Chapters 4-6 can be implemented in other macromodels, and are demonstrated using the macromodel presented in Chapter 3. The new techniques are validated over an extremely wide range of operating conditions: much wider than has been presented for previous macromodels, thus demonstrating the wide range of applicability of these techniques.

Mixed-Mode Simulation

Mixed-Mode Simulation PDF Author: Resve A. Saleh

Pages : 223

Book Description
Our purpose in writing this book was two-fold. First, we wanted to compile a chronology of the research in the field of mixed-mode simulation over the last ten to fifteen years. A substantial amount of work was done during this period of time but most of it was published in archival form in Masters theses and Ph. D. dissertations. Since the interest in mixed-mode simulation is growing, and a thorough review of the state-of-the-art in the area was not readily available, we thought it appropriate to publish the information in the form of a book. Secondly, we wanted to provide enough information to the reader so that a proto type mixed-mode simulator could be developed using the algorithms in this book. The SPLICE family of programs is based on the algorithms and techniques described in this book and so it can also serve as docu mentation for these programs. ACKNOWLEDGEMENTS The authors would like to dedicate this book to Prof. D. O. Peder son for inspiring this research work and for providing many years of support and encouragement The authors enjoyed many fruitful discus sions and collaborations with Jim Kleckner, Young Kim, Alberto Sangiovanni-Vincentelli, and Jacob White, and we thank them for their contributions. We also thank the countless others who participated in the research work and read early versions of this book. Lillian Beck provided many useful suggestions to improve the manuscript.
