摘要

XPSim(以前称为SuperCrystal)是一种适用于大型MOS VLSI电路的多速率事件驱动电路模拟器。XPSim结合了电路的静态和动态划分。采用一种新的积分方法——指数函数法对各分块子电路进行了数值求解。这种方法产生的电压波形是分段指数。目前，XPSim最多支持三阶显式方法。初步测试表明，XPSim在保持类似精度的同时，比SPICE表现出显着的加速，并且能够处理大型电路。

XPSim: a MOS VLSI simulator

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.<>
