Using the Model Editor to edit models
101
Running the Model Editor from the
schematic page editor
If you want to:
• test behavior variations on a part, or
• refine a model before making it available to all
designs,
then run the Model Editor from the schematic page editor
in Capture.
This means editing models for part instances on your
schematic page. When you select a part instance and edit
its model, the schematic page editor automatically creates
an instance model that you can then change.
Note
You can only edit models for device types that the Model Editor
supports. See Model Editor-supported device types on
page 4-95 for details.
What is an instance model?
An instance model is a copy of the part’s original model.
The copied model is local to the design. You can
customize the instance model without impacting any
other design that uses the original part from the library.
When the schematic editor creates the copy, it assigns a
unique name that is by default:
original_model_name-Xn
where n is <blank 1 | 2 | ... > depending on the number of
different instance models derived from the original model
for the current design.
