According to the Semiconductor Industry Association's 1999 International Technology Roadmap for Semiconductors, by the year 2008 the integration of more than 500 million transistors will be possible on a single chip. Integrating transistors on silicon will depend increasingly on design reuse. Design reuse techniques have become the subject of books, conferences, and podium discussions over the last few years. However, most discussions focus on higher-level abstraction like RTL descriptions, which can be synthesized. Design reuse is often seen as an add-on to normal design activity, or a special design task that is not an integrated part of the existing design flow. This may all be true for the ASIC world, but not for high-speed, high-performance microprocessors. In the field of high-speed microprocessors, design reuse is an integrated part of the design flow. The method of choice in this demanding field was, and is always, physical design reuse at the layout level. In the past, the practical implementations of this method were linear shrinks and the lambda approach. With the scaling of process technology down to 0.18 micron and below, this approach lost steam and became inefficient. The only viable solution is a method, which is now called Automatic Layout Modification (ALM). It combines compaction, mask manipulation, and correction with powerful capabilities. Automatic Layout Modification, Including design reuse of the Alpha CPU in 0.13 micron SOI technology is a welcome effort to improving some of the practices in chip design today. It is a comprehensive reference work on Automatic Layout Modification which will be valuable to VLSI courses at universities, and to CAD and circuit engineers and engineering managers.

iOS Auto Layout Demystified
Auto Layout re-imagines the way developers create user interfaces. It provides a flexible and powerful system that describes how views and their content relate to each other and to the windows and superviews they occupy. In contrast to older design approaches, this technology offers incredible control over layout with a wider range of customization than frames, springs, and struts can express. In this guide, Erica Sadun, bestselling author of The Core iOS 6 Developer's Cookbook and The Advanced iOS 6 Developer's Cookbook, helps readers learn how to use Auto Layout effectively, even masterfully, by providing an abundance of examples alongside plenty of explanations and tips. Instead of struggling with class documentation, you learn in simple steps how the system works and why it’s far more powerful than you first imagined. You read about common design scenarios and discover best practices that make Auto Layout a pleasure rather than a chore to use. Sadun includes examples of non-obvious ways to use Auto Layout to build interactive elements, animations, and other features beyond what you might normally lay out in Interface Builder to help expand the reader’s design possibilities. With this book you will learn The basic concepts that form the foundation of Auto Layout How to create clear and satisfiable rules of your layout, called constraints How to work effectively with the Interface Builder Layout What visual constraints look like, how to work with them, and how they are used in your projects How to debug constraints How to design interfaces when working with Auto Layout Effective solutions to the most common real-world problems and challenges Approximately 238 pages.
