ORCAD 的pspice9.1学习版本
PSpice 仿真器是一个全功能的模拟和混合信号仿真器，它支持从高频系统到低功耗IC设计的任何电路。其高级功能允许用户进行“What If”分析。PSpice强大的仿真引擎目前已方便地与Orcad Capture和Concept HDL原理图输入工具结合在一起，使工程师可以方便地在单一的环境里建立设计、控制仿真及得到结果。
PSpice产品包括：PSpice Studio、PSpice、PSpice A/D、PSpice A/D Basics和PSpice Advanced Analysis Option。
PSpice Studio
Includes all the functionality of PSpice? simulator with the built-in capabilities of PSpice Advanced Analysis.
PSpice
A full-featured simulator for serious analog designers. Sophisticated, internal models allow you to simulate everything from high-frequency systems to low-power IC designs. Draw on the expansive library of models to create off-the-shelf parts, or create models for new devices. Fully explore the relationships in your design with “what if” scenarios before committing to final implementation.
PSpice A/D
A sophisticated, native mixed-signal simulator and a superset of PSpice. Allows you to simulate mixed-signal designs of any size containing analog and digital parts. This includes everything from IGBTs and pulse-width modulators to DACs and ADCs. View your simulation results in both analog and digital from the same window and on the same time axis.
PSpice A/D Basics
An entry-level, mixed-signal simulation tool ideal for simulating simple, basic analog, or basic mixed-signal designs. PSpice A/D Basics imposes no limits on circuit size and performs functional simulation of digital parts in mixed-signal simulations allowing you to perform all the basic PSpice analyses.
PSpice Advanced Analysis Option
PSpice Advanced Analysis is a new product from Cadence featuring technology adapted from our Analog Workbench product. As an add-on option to PSpice or PSpice A/D, PSpice Advanced Analysis provides a unified environment for taking designs further – improving time-to-market performance and the overall quality of your design while keeping operating costs in check.
