1. A computer implemented method for statistical circuit simulation, comprising: providing descriptions of a circuit for simulation, wherein the descriptions include variations of statistical parameters of the circuit; partitioning the circuit into groups of netlists according to variations of statistical parameters of the circuit, wherein partitioning further comprises forming the groups of netlists according to proximity of variations of statistical parameters of the circuit, and wherein proximity of variations of statistical parameters comprises variations of threshold voltage of a transistor in a sub-threshold region, variations of threshold voltage of the transistor in a linear region, and variations of threshold voltage of the transistor in a saturation region; simulating the groups of netlists using a plurality of processors in parallel to generate a plurality of output data files, wherein the plurality of processors include a plurality of graphics processing units and a plurality of central processing units; and storing the plurality of output data files in a memory.
