Cadence OrCAD无法进行Pspice电路仿真

ERROR -- EVALUATION VERSION analog Node Limit (75 Nodes) Exceeded！

使用的是Cadence OrCAD 16.6的版本，Lite Version.
在其他地方说是版本的问题，所以有节点数限制。不知道哪位大神也用pspice仿真开关电源电路的，用的又是哪一版本的。
能我发个下载链接，拿就感激不尽了

Hi, with lite or evaluation version there always exist a limit in the number of nodes that can be simulated. PSpice orcad with medicine is available in here, why dont you download it? there are no limitations to that....
