Abstract

XPSim (formerly known as SuperCrystal), a multirate, event-driven circuit simulator suitable for large MOS VLSI circuits, is described. XPSim incorporates both static and dynamic partitioning of the circuit. Each partitioned subcircuit is numerically solved with a new integration method-the exponential function method. The voltage waveforms produced by this method are piecewise exponentials. Currently, XPSim supports up to a third-order explicit method. Preliminary tests indicate that XPSim exhibits a significant speedup over SPICE while retaining similar accuracy and is able to handle large circuits.<>
