Many prior works have discussed the power grid design and optimization in the post-layout stage, when design change is inevitably expensive and difficult. In contrast, during the early stage of a development cycle, designers have more flexibility to improve the design quality. However, there are several fundamental challenges at early-stage when design(More)
This paper proposes a fast and high-capacity electromagnetic solution, time-domain layered finite element reduction recovery (LAFE-RR) method, for high-frequency modeling and simulation of large-scale on-chip circuits. This method rigorously reduces the matrix of a multilayer system to that of a single-layer one regardless of the original problem size. More(More)
—A fast-marching time-domain layered finite-element reduction recovery (LAFE-RR) method is proposed for high-frequency modeling and simulation of large-scale integrated circuits. This method increases the time step of the LAFE-RR method by three orders of magnitude. In addition, it preserves the computational efficiency of the LAFE-RR method, i.e., the(More)
Power integrity has become increasingly important for sub-32nm designs. Many prior works have discussed power grid design and optimization in the post-layout stage, when design change is inevitably expensive and difficult. In contrast, during the early stage of a development cycle, designers have more flexibility to improve the design quality. However,(More)
—Time-domain layered finite element reduction recovery (LAFE-RR) method was recently developed for large-scale electromagnetic analysis of high-speed integrated circuits (ICs). This method is capable of analytically and rigorously reducing the system matrix of a 3-D multilayer circuit to that of a single-layer one regardless of the original problem size. In(More)
