AIDA-CMK: Multi-Algorithm Optimization Kernel Applied to Analog IC Sizing
This work addresses the research and development of an innovative optimization kernel applied to analog integrated circuit (IC) design. Particularly, this works describes the modifications inside the AIDA Framework, an electronic design automation framework fully developed by at the Integrated Circuits Group-LX of the Instituto de Telecomunicações, Lisbon. It focusses on AIDA-CMK, by enhancing AIDA-C, which is the circuit optimizer component of AIDA, with a new multi-objective multi-constraint optimization module that constructs a base for multiple algorithm implementations. The proposed solution implements three approaches to multi-objective multi-constraint optimization, namely, an evolutionary approach with NSGAII, a swarm intelligence approach with MOPSO and stochastic hill climbing approach with MOSA. Moreover, the implemented structure allows the easy hybridization between kernels transforming the previous simple NSGAII optimization module into a more evolved and versatile module supporting multiple single and multi-kernel algorithms. The three multi-objective optimization approaches were validated with CEC2009 benchmarks to constrained multi-objective optimization and tested with real analog IC design problems. The achieved results were compared in terms of performance, using statistical results obtained from multiple independent runs. Finally, some hybrid approaches were also experimented, giving a foretaste to a wide range of opportunities to explore in future work.
Yield-Aware Analog IC Design and Optimization in Nanometer-scale Technologies

This book presents a new methodology with reduced time impact to address the problem of analog integrated circuit (IC) yield estimation by means of Monte Carlo (MC) analysis, inside an optimization loop of a population-based algorithm. The low time impact on the overall optimization processes enables IC designers to perform yield optimization with the most accurate yield estimation method, MC simulations using foundry statistical device models considering local and global variations. The methodology described by the authors delivers on average a reduction of 89% in the total number of MC simulations, when compared to the exhaustive MC analysis over the full population. In addition to describing a newly developed yield estimation technique, the authors also provide detailed background on automatic analog IC sizing and optimization.
Sizing in Clothing
The basic concepts behind sizing systems currently used in the manufacture of ready-to-wear garments were originally developed in the 19th century. These systems are frequently based on outdated anthropometric data, they lack standard labelling, and they generally do not accommodate the wide variations of body sizes and proportions that exist in the population. However, major technological improvements have made new population data available worldwide, with the potential to affect the future of sizing in many ways. New developments in computer-aided design and sophisticated mathematical and statistical methods of categorizing different body shapes can also contribute to the development of more effective sizing systems. This important book provides a critical appreciation of the key technological and scientific developments in sizing and their application.The first chapter in the book discusses the history of sizing systems and how this has affected the mass production of ready-to-wear clothing. Chapters two and three review methods for constructing new and adapting existing sizing systems, and the standardisation of national and international sizing systems. Marketing and fit models are reviewed in chapter four whilst chapter five presents an analysis of the grading process used to create size sets. Chapters six and seven discuss fit and sizing strategies in relation to function, and the communication of sizing. Mass customization and a discussion of material properties and their affect on sizing are addressed in chapters eight and nine. Military sizing and the aesthetics of sizing are detailed in chapters ten and eleven. The final chapter reviews the impact on sizing of production systems and specifications.Written by an international team of contributors, this book is an essential reference to researchers, designers, students and manufacturers in the clothing and fashion industry. - Provides a critical appreciation of key technological and scientific developments in sizing and their application - Discusses how developments in sizing affect the mass production of ready to wear clothing - Reviews methods of constructing new and adapting existing sizing systems
