Abstract: Redundancy extraction in electromagnetic simulation of an electronic device/system includes discretizing first and second spaced conductive layers of a computer model of an electronic device/system into first and second meshes M1 and M2. For each edge between cells of each mesh, a current flow across the edge in response to application of an exemplary bias to the geometry is determined. A square impedance matrix Z* is determined which, for each instance of equal magnitude and opposite direction current flows (EMODCF) in edges E1 and E2 of M1 and M2, has one less row and one less column than the total number of edges in M1 and M2. A voltage column vector V* is also determined which, for each instance of EMODCF, has one less row than the total number of edges in M1 and M2. A current column vector [I*]=[V*]/[Z*] is then determined.

Abstract: In a method of electronic design automation, discretized meshes of layers of current conducting materials of a computerized device model are determined. Each discretized mesh corresponds to the current conducting material of one model layer. For each discretized mesh, a corresponding impedance matrix having cells is determined. Each cell includes an impedance value Zij which is based on a voltage (Vi) induced in a cell i of the discretized mesh due to a current (Ij) flowing in a cell j of the discretized mesh. A subset of the cells, including impedance values, of the impedance matrices is dispatched to node computers via an electronic communications network. In response to dispatching the cells of the impedance matrices, charge densities estimated by the node computers to exist on a subset of the cells of the discretized meshes are returned.

Abstract: In a method, system and computer readable medium for determining a composite circuit model of a 3D geometry, first and second sides of an analytical model of the 3D geometry are discretize into first and second surface and/or volume meshes. For each mesh, a current that flows in each cell thereof and the a voltage induced in the cell in response to the application of an exemplary bias to the geometry are determined. For each mesh, from the currents flowing in the cells thereof and voltages induced in the cells thereof, a corresponding circuit model is determined. The circuit models of the meshes are then combined to form a composite circuit model for the geometry.
