Abstract
A method and system for determining bi-directional sneak current paths of an electrical/electronic circuit. The electrical/electronic circuit is converted into a corresponding schematic having a plurality of components and a plurality of line segments. A segment identifier is then inserted into each of the plurality of line segments. Next, a DC analysis is performed on the electrical/electronic schematic for each possible switch position combination to obtain a current value for each of the plurality of components. Bi-directional sneak current paths are then determined based on the plurality of segment identifiers and the current value for each of the plurality of components.
