Hybrid 2D-3D Fast Electromagnetic Analysis aided by Pattern Recognition for Signal Integrity Analysis

摘要

The use of 3D full-wave electromagnetic solvers for signal integrity analysis is often hindered by its prohibitive time and memory requirements. In this work, a hybrid 2D-3D solver is proposed to address the computational challenges while still preserving the desired accuracy. The method is based on an image based segmentation technique followed by 2D-3D classification for each segment, analysis and cascading transfer functions. A figure of merit that accurately represents simulation accuracy in frequency domain is identified for the 2D-3D prescription. Numerical results for a 13" trace is presented and the benefit in simulation time versus accuracy are highlighted.
