Abstract: The objective of this work is to investigate high-performance electromagnetic field finite element solver towards high resolution and high fidelity electromagnetic simulations of product-level ICs and electronics. The emphasis of this work is to overcome the parallel bottleneck of multiscale problems and fulfill full-wave electromagnetic simulation of complex problems. Numerical simulation software can be developed quickly based on our software-platform. Finally, the capability and benefits of the algorithms are validated and illustrated through practical simulation of chip in computer case.
