Hello,
I'm trying to simulate a fairly simple two-BJT amplifier, which uses MPSA18 transistors, which I found with the "transistor.olb" library. When I try to simulate, though, I get these:
WARNING(ORNET-1119): No PSpiceTemplate for Q1, ignoring
WARNING(ORNET-1119): No PSpiceTemplate for Q2, ignoring
I suspect this is because there is no corresponding "transistor.lib" file in my C:\OrCAD\OrCAD_16.5_Lite\tools\pspice\library folder. In fact, there aren't nearly as many .lib files as there are .olb files.
Is there somewhere I can find the library(ies) I need, or am I doomed to a limited number of models since I'm using the Lite version of Capture? Or am I having a completely different problem? Thanks a ton.
The issue is that the Schematic parts that you placed are from the general purpose libraries and therefore don't have the necessary properties to make a PSpice netlist, specifically, but not exclusively, the PSpiceTemplate property, hence the message. This property maps the Schematic pin names on the Schematic part to the Pin Order on the model. For a .MODEL defined transistor, this would be:
Q^@REFDES %c %b %e @MODEL
The Schematic Part Pin Names would need to be c for the Collector, b for the Base and e for the Emitter for this template to work. You also need an Implementation Type property of PSpice Model and an Implementation property of the Model Name, MPSA18 in this case.
See the PSpice Users Guide, pspug.pdf in the doc\pspug directory of the installation for details. The "Lite" version has restricted Model Editor capabilities so you probably won't be able to use this to make a Library from the LIB file that you have.
