Abstract: "This thesis presents several techniques for the analysis of substrate-coupled noise in mixed-signal integrated circuits. Advantages and limitations of several commonly employed analysis techniques for substrate coupling are outlined. A preprocessed boundary element technique introduced in this thesis is shown to overcome all the limitations of the prior approaches and results that confirm its accuracy and superior performance are presented. Methods are also discussed that dramatically accelerate the solution of the preprocessed boundary element equations. A methodology that applies these fast techniques to the verification of large mixed-signal circuits and results that confirm its efficiency are described. An application of this complete methodology to the design and verification of an industrial mixed-signal video analog-to- digital converter IC for substrate noise problems that ensured its success on first pass silicon is presented."

This book is the first in a series of three dedicated to advanced topics in Mixed-Signal IC design methodologies. It is one of the results achieved by the Mixed-Signal Design Cluster, an initiative launched in 1998 as part of the TARDIS project, funded by the European Commission within the ESPRIT-IV Framework. This initiative aims to promote the development of new design and test methodologies for Mixed-Signal ICs, and to accelerate their adoption by industrial users. As Microelectronics evolves, Mixed-Signal techniques are gaining a significant importance due to the wide spread of applications where an analog front-end is needed to drive a complex digital-processing subsystem. In this sense, Analog and Mixed-Signal circuits are recognized as a bottleneck for the market acceptance of Systems-On-Chip, because of the inherent difficulties involved in the design and test of these circuits. Specially, problems arising from the use of a common substrate for analog and digital components are a main limiting factor. The Mixed-Signal Cluster has been formed by a group of 11 Research and Development projects, plus a specific action to promote the dissemination of design methodologies, techniques, and supporting tools developed within the Cluster projects. The whole action, ending in July 2002, has been assigned an overall budget of more than 8 million EURO.

This monograph, divided into four parts, presents a comprehensive treatment and systematic examination of cycle spaces of flag domains. Assuming only a basic familiarity with the concepts of Lie theory and geometry, this work presents a complete structure theory for these cycle spaces, as well as their applications to harmonic analysis and algebraic geometry. Key features include: accessible to readers from a wide range of fields, with all the necessary background material provided for the nonspecialist; many new results presented for the first time; driven by numerous examples; the exposition is presented from the complex geometric viewpoint, but the methods, applications and much of the motivation also come from real and complex algebraic groups and their representations, as well as other areas of geometry; comparisons with classical Barlet cycle spaces are given; and good bibliography and index. Researchers and graduate students in differential geometry, complex analysis, harmonic analysis, representation theory, transformation groups, algebraic geometry, and areas of global geometric analysis will benefit from this work.

The goal of putting `systems on a chip' has been a difficult challenge that is only recently being met. Since the world is `analog', putting systems on a chip requires putting analog interfaces on the same chip as digital processing functions. Since some processing functions are accomplished more efficiently in analog circuitry, chips with a large amount of analog and digital circuitry are being designed. Whether a small amount of analog circuitry is combined with varying amounts of digital circuitry or the other way around, the problem encountered in marrying analog and digital circuitry are the same but with different scope. Some of the most prevalent problems are chip/package capacitive and inductive coupling, ringing on the RLC tuned circuits that form the chip/package power supply rails and off-chip drivers and receivers, coupling between circuits through the chip substrate bulk, and radiated emissions from the chip/package interconnects. To aggravate the problems of designers who have to deal with the complexity of mixed-signal coupling there is a lack of verification techniques to simulate the problem. In addition to considering RLC models for the various chip/package/board level parasitics, mixed-signal circuit designers must also model coupling through the common substrate when simulating ICs to obtain an accurate estimate of coupled noise in their designs. Unfortunately, accurate simulation of substrate coupling has only recently begun to receive attention, and techniques for the same are not widely known. Simulation Techniques and Solutions for Mixed-Signal Coupling in Integrated Circuits addresses two major issues of the mixed-signal coupling problem -- how to simulate it and how to overcome it. It identifies some of the problems that will be encountered, gives examples of actual hardware experiences, offers simulation techniques, and suggests possible solutions. Readers of this book should come away with a clear directive to simulate their design for interactions prior to building the design, versus a `build it and see' mentality.

(Cont.) Existing techniques have prohibitively long simulation times and are only suitable for final verification. Determination of substrate noise coupling during the design phase would be extremely beneficial to circuit designers who can incorporate the effect of the noise and re-design accordingly before fabrication. This would reduce the turn around time for circuits and prevent costly redesign. SNAT can be used at any stage of the design cycle to accurately predict (less than 12% error when compared to measurements) the substrate noise performance of any digital circuit with a large degree of computational efficiency.

An analysis of substrate noise coupling in mixed-signal circuits has been performed in the TSMC 0.25 [mu]m lightly doped and heavily doped CMOS processes. Methods to minimize noise coupling in both the chip design and board design phases are presented along with techniques for accurate circuit simulation of noise coupling. Measurements from test chips validate simulations performed using Silencer!. Suggestions for reducing substrate noise coupling are also provided. Measurements and simulations show a 15 dB improvement in substrate noise coupling in the lightly doped substrate when compared with the heavily doped substrate with the backplane floating. When no mutual inductance is present and the backplane is grounded through a low impedance, a 17.5 dB improvement in substrate noise coupling is observed in the heavily doped process. Simulations with guard rings show an 8 dB improvement in substrate noise coupling in the heavily doped case and 3.4 dB improvement in the lightly doped case.

The tools and techniques you need to break the analog design bottleneck! Ten years ago, analog seemed to be a dead-end technology. Today, System-on-Chip (SoC) designs are increasingly mixed-signal designs. With the advent of application-specific integrated circuits (ASIC) technologies that can integrate both analog and digital functions on a single chip, analog has become more crucial than ever to the design process. Today, designers are moving beyond hand-crafted, one-transistor-at-a-time methods. They are using new circuit and physical synthesis tools to design practical analog circuits; new modeling and analysis tools to allow rapid exploration of system level alternatives; and new simulation tools to provide accurate answers for analog circuit behaviors and interactions that were considered impossible to handle only a few years ago. To give circuit designers and CAD professionals a better understanding of the history and the current state of the art in the field, this volume collects in one place the essential set of analog CAD papers that form the foundation of today's new analog design automation tools. Areas covered are: * Analog synthesis * Symbolic analysis * Analog layout * Analog modeling and analysis * Specialized analog simulation * Circuit centering and yield optimization * Circuit testing Computer-Aided Design of Analog Integrated Circuits and Systems is the cutting-edge reference that will be an invaluable resource for every semiconductor circuit designer and CAD professional who hopes to break the analog design bottleneck.
