Abstract

A Robin transmission condition (RTC) enhanced discontinuous Galerkin method (DGM) is proposed for direct current IR-Drop analysis of global PDN. Although DGM is one kind of domain decomposition method (DDM) naturally, it suffers much more number of unknowns compared with finite element method (FEM). To overcome this drawback, RTC is introduced to serve as a transmission condition apart from the numerical flux. As a result, the volume unknowns appeared in traditional DG method is elegantly transferred to the interface among neighboring subdomains. Thus, the DoFs are markedly reduced. To validate the proposed method, a representative numerical result is presented at the last of this paper.
