TOLERANCING AND OPTIMIZATION FOR MODEL-BASED ROBUST ENGINEERING DESIGN

摘要

There are various methods for performing tolerancing and robust design within a computer-aided design (CAD) framework. Recent work on fitting statistical emulators to CAD systems can be used to facilitate fast optimization geared towards robustness against input variation. After discussing available methods for tolerancing within a common framework, a comprehensive strategy for robust design is developed which involves a combination of circuit simulation, emulation and global optimization.
