Re: What is PSpice
There are standard MODELs that comes with PSPICE software in the PSPICE library, you can add MODELS to user library after you download it off the net eg.
h**p://homepages.which.net/~paul.hills/Circuits/Spice/ModelIndex.html
You can read about MODELS in HELP files
eg. Overview of the Model Editor
You can use the Model Editor to determine the model parameters for many standard device types, such as bipolar transistors, and to create the subcircuit models for more complex device types, such as operational amplifiers. You can create accurate models and parts for off-the-shelf devices by converting information from the device manufacturer's data sheet into PSpice model parameter values, without taking measurements of a real device. Then you can include the new, custom device model as part of your own model library.

The nodes are in the NETLIST with the properties of the components ie the value, name of the model and designator.
They are(NODES) created when you construct the schematic in PSPICE, the properties of the components you can edit in the schematic also.
