.SUBCKT definitions
For definitions implemented as subcircuit netlists using PSpice
.SUBCKT syntax, the model editor displays the subcircuit
syntax exactly as it appears in the model library. The model
editor also includes all of the comments immediately before or
after the subcircuit definition.

the model name
You can change the model name directly in the PSpice .MODEL
or .SUBCKT syntax, but should double-check that the new
name does not conflict with models already contained in the
libraries.
Note
If you do create a model with the same name as
another model and want PSpice A/D to always use
your model, make sure the confi
g
ured model
libraries are ordered so your definition precedes
any other definitions.
