How to use .cir model in Capture

    经常碰到orcad仿真库中找不到某些器件的情况，但是从这些器件的厂家网站上往往可以下到其spice model，一般是.cir文件，下面介绍一下如何使用这些.cir文件。以AD8131.cir为例。
    首先，运行Model Editor (in PSpice Accessories)，打开ADAD8131.cir文件，另存为（save as）AD8131.lib，add this to pspice library,for simulation purpose.
    use File->Export to capture part library… ,to generate AD8131.olb，add this to capture library，this can perform circuit connection.
    when you run simulation ,open simulation setting/configuration  file/library add  the AD8131.lib to this design.
