Ways to create and edit models
This section is a roadmap to other information in this
chapter. Find the task that you want to complete, then go
to the referenced sections for more information.
If you want to... Then do this... To find out more, see this...
➥ Create or edit the model
for an existing part
and
have it affect all designs that
use that part.
Create or load the part first in
the part editor, then edit the
model using the Model
Editor *.
* For a list of device types that the Model Editor supports, see
Model Editor-supported device types on page 4-95
.
If the Model Editor does not support the device type for the model definition that you want to create, then you can edit the text
using the Model Editor to create a model definition using the PSpice .MODEL and .SUBCKT command syntax. Remember to
configure the new model library.
Running the Model Editor
from the schematic page editor
on page 4-101
..
➥ Create a model from
scratch and
automatically create a
part for it
to use in any
design.
➥ Create a model from
scratch without a part
and have the model
definition available to any
design.
➥ View model
characteristics
for a part.
Start the Model Editor * and
enable/disable automatic part
creation as needed; then create
or view the model.
Running the Model Editor
alone on page 4-99
.
➥ Define tolerances
on
model parameters for
statistical analyses.
Select the part instance on your
schematic, then edit the model
using the Model Editor.
Starting the Model Editor from
the schematic page editor in
Capture on page 4-111
.
➥ Test behavior
variations
on a part.
➥ Refine a model
before
making it available to all
designs.
Select the part instance on your
schematic page, then edit the
model using the Model
Editor *.

➥ Derive subcircuit
definitions
from a
hierarchical design.
Use the Create Subcircuit
command in the schematic
page editor.
