Title: Eigenvalue Problems and Model Order Reduction in Industry

Speaker: Joost Rommes, NXP Semiconductors, Corp. I&T/DTF,

Abstract: Physical structures and processes are modeled by dynamical systems in a wide range of application areas. During the design of very large-scale integration (VLSI) chips, for instance, dynamical systems are used to describe the low-level circuit behavior. Since these dynamical systems can become very large for modern chips, the essential simulation before production may consume hours or days of computing time. Hence there is need for efficient mathematical approaches that limit the computing time while preserving the accuracy. In this talk it will be shown how specialized eigenvalue methods and model order reduction techniques can be used to perform fast and accurate simulations of large dynamical systems. Results will be illustrated by numerical experiments with realistic examples. 1
