TOLERANCING AND OPTIMIZATION FOR MODEL-BASED ROBUST ENGINEERING DESIGN

There are various methods for performing tolerancing and robust design within a computer-aided design (CAD) framework. Recent work on fittin g 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 involv es a combination of circuit simulation, emulation and global optimizat ion.
