摘　　要：SPICE是通用的电路模拟程序 ,它最早是由美国的伯克力大学于 1975年开发的 ,是 EDA技术的基础。目前多数电路模拟应用软件都是以 SPICE为基础的 ,Multisim就是以 SPICE为内核的电路模拟软件。但是在 SPICE中不能直接以时间为变量为信号建模 ,因此限制了它的应用。本文介绍在 SPICE中抽取时间量的方法 ,利用 SPICE中的非线性受控源和时间变量可以组成各种波形的信号源 ,使用目前流行的交互式电路模拟软件 Multisim,所创建的时间元件和信号源元件存储在 Multisim的用户元件库中供调用。最后给出了一个使用所创建的信号源进行电路模拟的实例。SPICE originally developed at the Electronics Reserach Laboratory of the University of California , Berkeley(1975), is a general purpose program for circuit simulation, which is the basis of EDA technology. Most application programs for circuit simulation are based on SPICE, such as Multisim. But SPICE does not model signal straight-forward with time, so limiting its applications. Time data could be extracted with the method introduced in this article. The nonlinear dependent source and time variable are used to model various waveform sources. Multisim is used in the article which is considered as a real interactive circuit simulation software. The timer component and signal components created are saved in the user's library. A typical example of circuit simulation using the created signal source is included.
