Large-scale capacitance calculation

Abstract: We describe a new method for accurate large-scale capacitance calculations. The algorithm uses an integral equation formulation, but with a new representation for charge distributions that decouples charge variation from conductor geometry. This separation significantly reduces the problem size compared to a traditional discretization, resulting in a large speed increase. The full capacitance matrix of typical interconnect problems with thousands of nets can be computed in a few hours.

“…Substituting (11) and (12) into (10) generates a meshed system that can be solved by an iterative method coupled with an accelerated matrix-vector product technique [1], [2], [3], [4], [5]. The solution of I m subsequently allows one to determine branch currents in I b that contains the actual basis function weights.…”

“…To date, there exists numerous accelerated integral-equation based electromagnetic solvers [1], [2], [3], [4], [5], [6] that are capable of rapid and accurate resolution of large conductor system impedance, some of which can even account for the effects invoked by the presence of a semi-conductive substrate. However, the efficiency of these solvers is being continuously challenged by the ever increasing operating frequencies which generate skin and proximity effects that need to be carefully modeled in order to provide accurate impedance solutions.…”

“…Interaction matrices of the form (1.1), with the Green's function possibly replaced with its three dimensional analogue, may occur as system matrices in a variety of situations in materials science and electrical engineering, for example, particle coarsening and capacitance extraction [14,15,18,19]. The particular application which drives this work concerns Laplace's equation and the DirichletNeumann map in domains exterior to a number n of closed contours -a problem which, in turn, has relevance for microstructural evolution, see Ref.…”

“…Reasons for this may include that the problems at large n could be most pronounced in two dimensions. Should the Greens' function in (1.1) be replaced with a more rapidly decaying one, established preconditioners are reported to work satisfactorily [15,18,20,23]. Furthermore, efficient linear solvers for large systems involve other key components besides preconditioners.…”

“…The first generation of fast field solvers used dense matrix compression methods such as the Fast Multipole Method (FMM), the Precorrected-FFT (PFFT), and SVD compression [3,4,5,6,10]. All these methods decompose the matrix into an explicit direct part and a implicit far-field part.…”
