在orcad中点击"PSPICE" 》edit simulation profile 》configuration files 》browse 》把你的lib文件（你的应该是DB3.lib）加入即可（点击add to design，不行就再点击 add as global）。
op-07应该是个运放，元件所在的库没有添加到你所做的工程中。至于如何添加，由于你没有说明用cadence干嘛，操作会有所不同。找到configuration file---library--

I downloaded the trial version of OrCad Pspice. I'm trying to do some simulation using Capture with opamp and transistor but it doesn't work. The error message is:ERROR(ORPSIM-15108): Subcircuit UA798 used by X_U1A is undefined. How can I solve the probl
The spice model from OnSemi is bad. There is no subcircuit named "RSFFPC_ABM" but there are three statements in the .lib file that call "RSFFPC_ABM". The spice "glue" is X_U1, X_U3, X_U4 and X_U6. You should notify OnSemi that the model is incomplete. Thanks for the reply...
