Abstract
The method of the present invention determines the voltage, current, and/or power distribution in a power supply or other resistive network containing holes or contacts having non-rectangular boundaries. The method includes applying a grid over the resistive network. Because the holes and contacts have non-rectangular boundaries, the grid lines are not always coincident with these boundaries. A set of modified finite difference equations are then solved to derive a voltage distribution. Unlike conventional methods, these equations have been specifically adapted to the non-rectangular boundaries of the holes and contacts.
