WEMA4: Power Integrity in the Era of Advanced Packaging: Changing the Paradigm of FEM

Abstract
Computational electromagnetic solvers will often utilize tetrahedra and adaptive meshing to provide accurate results. This methodology has presented many challenges from capacity to solve time. By changing the paradigm away from tetrahedra and instead shifting to triangular prisms, meshing can be sped up while maintaining accuracy. Problems that used to be unsolvable with traditional FEM tetrahedra-based methods can instead be handled by triangular prisms. This seminar will explore the state-of-the-art possibilities of handling massive interposers that would previously be restricted to 2.5D solvers.
