Matrix reduction tool for creating boundary condition independent dynamic compact thermal models

A novel matrix reduction method for the efficient and automatic construction of boundary condition independent dynamic compact thermal models having a chosen accuracy, is proposed. The method is implemented in a code which allows constructing boundary condition independent dynamic compact thermal models of any multi-die package modeled within a 3-D commercial mesher. The proposed approach has many advantages with respect to previous approaches in terms of robustness, efficiency, and applicability. The method is validated through the analysis of a dual-flat no-leads 12-leads package.
