Spice tools available: SBTSPICE, HSPICE, Spectre, TSPICE, Pspice, Smartspice ... Most of the SPICE tools are originated from Berkeley’s SPICE program, therefore support common original SPICE syntax Basic algorithm scheme of SPICE tools are similar, however the control of time step, equation solver and convergence control might be different. Spice Overview SPICE Simulation Algorithm - DC Spice Overview SPICE Simulation Algorithm - Transient Spice Overview 在用Spice进行电路仿真之前，应： 了解元件的基本特性 熟悉所设计的电路功能 了解需要验证的电路指标和对应的模拟种类、电路 状态 了解电路的输入信号特性 了解电路各项指标的相依性及优先度 了解电路结构、元件参数与各项电路特性的相关 性，以便于模拟结果的改进 Hspice的流程 前端功能 MetaLib CDF Schematic Symbol Library HSPICE Netlister Netlist HSPICE Simulation Parameter
