Abstract:
1. A method of determining a distribution of voltages or currents in a plurality of layers of a multi-layer circuit design in response to energization of the circuit design with an exemplary bias, the method comprising: (a) discretizing an exemplary current that flows in each layer of a multi-layer circuit design in response to an application of an exemplary bias to the circuit design into a plurality of currant vector elements on said layer; (b) determining for each current vector element on each layer at least one corresponding scalar charge element on said layer; (c) determining for each layer from the current vector elements on the plurality of layers, a spectrum of a first electromagnetic (em) field induced in the layer; (d) determining a first distribution of voltages induced in each layer from the spectrum of the first electromagnetic (em) field induced in said layer; (e) determining for each layer from the scalar charge elements on the plurality of layers, a spectrum of a second em field induced in the layer; (f) determining a second distribution of voltages induced in each circuit layer from the spectrum of the second em field induced in said layer; and (g) determining for each layer from the first and second distributions of voltages induced in the layer, a distribution of voltages in the layer.
