Inductance calculation of 3D superconducting structures with ground plane
An inductance calculation method, which is based on calculating the current distribution of a fluxoid-trapped superconducting loop by using the expression of momentum and the Maxwell equations, is reconstructed to enable calculation of arbitrary 3D structures which have a ground plane (GP). Calculation of the mutual inductances of the superconductor system is also incorporated into the algorith...
متن کاملEquipotential shells for efficient inductance extraction
To make three-dimensional (3-D) on-chip interconnect inductance extraction tractable, it is necessary to ignore parasitic couplings without compromising critical properties of the interconnect system. It is demonstrated that simply discarding faraway mutual inductance couplings can lead to an unstable approximate inductance matrix. In this paper, we describe an equipotential shell methodology, ...
متن کاملFast on-chip inductance simulation using a precorrected-FFT method
In this paper, a precorrected-FFT approach for fast and highly accurate simulation of circuits with on-chip inductance is proposed. This work is motivated by the fact that circuit analysis and optimization methods based on the partial element equivalent circuit (PEEC) model require the solution of a subproblem in which a dense inductance matrix must be multiplied by a given vector, an operation...
متن کاملCircuit-Aware On-chip Inductance Extraction
In this paper we propose a practical approach for on-chip inductance extraction. This approach differs from previous methods in that it uses circuit characteristics to obtain a sparse, stable and symmetric inductance matrix, using the concept of resistance dominant and inductance dominant lines. Experimental results show that only the important inductance terms related to strong inductance coup...
متن کاملEfficient inductance extraction using circuit-aware techniques
We propose two practical approaches for on-chip inductance extraction to obtain a highly sparsified and accurate inverse inductance matrix K. Both approaches differ from previous methods in that they use circuit characteristics to obtain a sparse, stable and symmetric K, using the concept of resistance-dominant and inductance-dominant lines. Specifically, they begin by finding inductance-domina...
