Model Properties
The model editor window contains an edit area that displays the
PSpice commands and netlist entries for the model definition.
You can freely edit the definition just as you would in any
standard text editor.

.MODEL definitions
For definitions implemented as model parameter sets using
PSpice .MODEL syntax, the model editor lists one parameter
per line. This makes it easier to add DEV/LOT tolerances to
model parameters for Monte Carlo or sensitivity/worst-case
analysis.
If the model is an AKO (see sidebar) and you want to view all
of the parameters that are available, you can have the model
editor flatten the AKO hierarchy into one model definition.
To convert an AKO model into a non-AKO model

AKO (A Kind Of) models are
based on another model, and
inherit the parameter values of
the base model. Any parameters
defined for the AKO model
supersede those inherited from
the base model. See Fi
