Hierarchical Block Boundary Element Method for Substrate Resistance Calculation

It is important to model the substrate coupling for today's mixed-signal circuit design. This paper presents the hierarchical block boundary element method (HBBEM) for substrate resistance calculation. HBBEM, which can extract the whole interconnect capacitance matrix with once computation, is applied to the substrate resistance calculation. Experiments show that the proposed method is able to produce results with comparable accuracy, and of higher efficiency than existing methods both in running time and memory usage
