The Parts utility converts information that you enter from the
part manufacturer’s data sheet into either:
• model parameter sets using PSpice .MODEL syntax, or
• subcircuit netlists using PSpice .SUBCKT syntax,
and saves these definitions to model libraries that PSpice A/D
can search when looking for simulation models.
