Numerical Aspects of Xyce (TM): Equations, Solvers Needs

402 Walter Library

The Xyce (TM) Parallel Electronic Simulator is a state-of-the-art circuit modeling code written to support the simulation needs of the Sandia National Laboratories electrical designers. This development has focused on providing the capability to solve extremely large circuit problems by supporting large-scale parallel computing platforms. In addition, it provides improved performance and robustness for numerical kernels by using modern algorithms via library implementations of these methods developed over the past ten years. As many of the equations and resulting numerics of circuit simulation are different from those of PDE simulations codes. This talk will discuss these differences followed by a description of the current solver environment used by Xyce and its needs for future improvements.

 

Scott Hutchinson received his Ph.D. in 1993 from New Mexico State University in Electrical Engineering studying Computational Electromagnetics. Since that time, he has been with the Computational Sciences Department at Sandia National Laboratories in Albuquerque, New Mexico where he has worked on modeling reacting flows (MPSalsa), Krylov solvers (Aztec) and a variety of other projects. Dr. Hutchinson is currently the technical lead on a next-generation circuit simulation tool (Xyce), being developed at Sandia National Laboratories.
