1 ) A method for parallel simulation of general time-domain differential/nonlinear circuits and mixed-domain formulations that are represented by nonlinear/linear differential algebraic equations (NDAEs) by partitioning them into smaller subcircuits via a novel combination of the companion form representation of the given circuit and an efficient form of node splitting, with the coupling between subcircuits being represented by binary vectors, during Newton Raphson iterations, at any time point, including DC.
