A Parallel Preconditioned Finite Element Method and Its Applications in System-in-Package Electromagnetic Simulations
In the electromagnetic compatibility analysis and signal integrity analysis
it is difficult to do full-wave electromagnetic simulation of system-in-package (SiP) due to its complex
multi-scale and multi-material characteristics. Here
we present a high-performance program JEMS-CDS developed on parallel infrastructure JAUMIN and its high-efficiency algorithms in SiP electromagnetic simulations. A positive definite matrix is constructed by analyzing the FEM matrix built for SiP simulation. Numerical results show that better convergence performance than traditional ones can be achieved
as well as a high parallel efficiency when scaling to hundreds of CPU cores with nearly one hundred millions unknowns. Finally
a practical product is simulated to acquire the high-resolution distribution of electromagnetic
supporting the analysis of electromagnetic compatibility and signal integrity.
