A Computer-Aided Design and Synthesis Environment for Analog Integrated Circuits addresses the design methodologies and CAD tools that are available for the systematic design and design automation of analog integrated circuits. Two complementary approaches are discussed.
In the first part the AMGIE analog synthesis system is described. AMGIE is the first analog synthesis system that automates the full design process from specifications down to verified layout. It is targeted to the design of moderate-complexity circuits. It relies on design and circuit knowledge stored in the tool's libraries and can be used by both novice and experienced analog designers as well as system-level designers. The inner workings are explained in detail, with (practical) examples to demonstrate how the implemented algorithms and techniques work. Experimental results obtained with the AMGIE system are reported, including actual fabricated and measured circuits.
The second approach, i.e. the systematic design of high-performance analog circuits, is discussed in the second part of the book. This approach is supported by tools to boost the productivity of the designer. An example of such a tool is Mondriaan, that is targeted towards the automatic layout generation of highly regular analog blocks. The proposed systematic design methodology is then applied to the design of high-accuracy current-steering digital to analog converters (DACs). The full design path is discussed in detail. By using the Mondriaan tool and other in-house developed and commercially available tools, the first 14-bit accurate current-steering DAC without tuning or trimming in CMOS technology has been fabricated and measured.
Both complementary approaches increase analog design productivity. Design times of the different design experiments undertaken are reported throughout the book to demonstrate this.
A comprehensive analysis of current theory and research in the psychological, computational, and neural sciences elucidates the stuctures and processes of language and thought. Chapters discuss language comprehension and artificial intelligence, ARCS system for analogical retrieval, ACME model of analogical mapping, PAULINE, an artificial intelligence system for pragmatic language generation, a theory of understanding of spoken and written text, recent developments and effect of different modes of language representation on the efficiency of information processing. This book will be of interest to professionals and scholars in psychology, artificial intelligence, and cognitive science.
This book allows readers to expand the versatility of AutoCADÂ® design and documentation software. It provides ready-to-use procedures and computer programs for solving problems in a variety of application areas, including computer-aided design, data visualization, evolutionary computation, numerical methods, single and multicriteria optimization, linkage and robot kinematics, cam mechanisms, and involute gears.
Students, engineers, and scientists alike will benefit from the text's illustrative examples, first-rate figures, and many original problem-solving approaches, as well as the included software tools for producing high-quality graphs and simulations. Those who use AutoCAD LT, or have access to only a DXF viewer, can also make substantial use of this book and the accompanying programs and simulations.
The first two chapters of this book describe plotting programs D_2D and D_3D, which have many features not yet available in popular software like MATLABÂ® or MathCAD. Both plotting programs are available with the book. Other chapters discuss motion simulation of planar mechanical systems, design and analysis of disk cam mechanisms, and how to use the Working Model 2D and AutoLISP applications to demonstrate how involute gears operate. The book concludes with a collection of practical problems that can be solved using the programs and procedures discussed earlier in the book.
