This book presents a detailed summary of research on automatic layout of device-level analog circuits that was undertaken in the late 1980s and early 1990s at Carnegie Mellon University. We focus on the work behind the creation of the tools called KOAN and ANAGRAM II, which form part of the core of the CMU ACACIA analog CAD system. KOAN is a device placer for custom analog cells; ANANGRAM II a detailed area router for these analog cells. We strive to present the motivations behind the architecture of these tools, including detailed discussion of the subtle technology and circuit concerns that must be addressed in any successful analog or mixed-signal layout tool. Our approach in organizing the chapters of the book has been to present our algo­ rithms as a series of responses to these very real and very difficult analog layout problems. Finally, we present numerous examples of results generated by our algorithms. This research was supported in part by the Semiconductor Research Corpora­ tion, by the National Science Foundation, by Harris Semiconductor, and by the International Business Machines Corporation Resident Study Program. Finally, just for the record: John Cohn was the designer of the KOAN placer; David Garrod was the designer of the ANAGRAM II router (and its predeces­ sor, ANAGRAM I). This book was architected by all four authors, edited by John Cohn and Rob Rutenbar, and produced in finished form by John Cohn.

Careful and systematic planning is essential to the success of your library's technology implementation efforts. This complete, clear, and easy-to-follow guide takes a highly practical, hands-on approach to thoroughly prepare public, academic, school and special libraries to develop and implement a technology plan in the library. Following a foreword from Executive Director of the American Library Association Keith Michael Fiels, authors John M. Cohn and Ann L. Kelsey provide a comprehensive introduction to the key concepts and elements in technology planning and the changing technological landscape affecting today's libraries. There is clear advice to help you best define your plan's scope, purpose and funding requirements, along with step-by-step guidance for developing an effective technology plan - from gathering data and identifying institutional needs, to determining priorities, identifying objectives, outlining costs and writing the actual plan. A five-step model plan is included to provide readers with a start-to-finish example of the development process, and the authors also advise on how to implement the new plan and evaluate its success. The accompanying CD-ROM includes over thirty-five time-saving, sample technology plans and RFPs. Each plan is specifically targeted to public, academic, school, or special libraries, and can be easily replicated or adapted for use in your own institution. An array of figures, checklists, and examples are included throughout the book to help reinforce important concepts, and a comprehensive webliography lists further related resources.

Designed for librarians, this guide explains how to create, implement, update, evaluate and use a detailed technology plan. It describes how plans are developed, how to maintain them and how to use them as leverage for grant and budget applications. A CD-ROM contains a variety of examples.
