Abstract:The co-simulation of a die and a package results in numerical problems of ultra-large scale, requiring billions of parameters to describe them accurately. In this paper, an orthogonal finite-element reduction-recovery method is proposed to overcome the large problem sizes encountered in the simulation of an integrated die-package system. In this method, a set of orthogonal prism vector basis functions are developed to render the surface-unknown-based matrix in each layer diagonal. An arbitrary 3D multilayered … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
