In this work, the authors developed a fast electromagnetics-based nonlinear-linear co-simulation algorithm based on a recently developed time-domain orthogonal finite-element reduction-recovery method (OrFE-RR). In this method, the linear part and the nonlinear part are naturally decoupled due to the diagonal matrix in the single surface system. Meanwhile, as the devices are usually not connected...
The scaling of supply voltages and the increased level of integration have conspired to make the analysis and design of microelectronic systems increasingly challenging. The impact of dynamic noise due to signal switching, die-package coupling, power management techniques, substrate coupling, etc., can been seen at all levels of a power delivery network, from chip to package to mother board to the...
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 matrix reduction is achieved analytically from...
As on-chip design scales into the nanometer regime, full-wave electromagnetics (EM)-based analysis has increasingly become essential for four main reasons: (1) reduced feature sizes that lead to subwavelength optical lithography, (2) increased clock frequency, (3) the transition from single core to multicore, and (4) increased level of integration. However, the design of next- generation ICs results...
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 important, the matrix reduction is achieved...
In this paper, we develop a time-domain layered finite element reduction recovery (TD-LAFE-RR) method to solve large-scale IC design problems at high frequencies. This method rigorously reduces the matrix of the original multilayer system to that of a single-layer no matter how large the original problem is. More importantly, the matrix reduction is achieved analytically, and hence the CPU and memory...
