Abstract

Thanks to the application of GPU-CUDA acceleration technology to EM simulation tools, more and more complicated EMI challenges can be efficiently investigated and solved very early in the design process. This paper presents a novel methodology to predict EMI emission due to memory SSO noise from a real, commercial graphics card by means of a commercially available CUDA accelerated full-wave FDTD simulator. It is shown that thanks to the CUDA acceleration one can estimate the influence of on-board decoupling capacitors on the EMI emission within hours.
