Filed:

Apr 8, 2011

Appl. No.:

13/082818

International Classification:

G06F 17/10

US Classification:

703 2

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 M and M. 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 E and E of M and M, has one less row and one less column than the total number of edges in M and M. 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 M and M. A current column vector [I*]=[V*]/[Z*] is then determined.

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.
