Using the Model Editor to
edit models
The Model Editor converts information that you enter
from the device 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
can search when looking for simulation models.
Figure 27 Relationship of the Model Editor to Capture and
PSpice.
Note
By default, the Model Editor creates or updates model libraries. To
create an exported model file, choose the Export command from
the Model menu and configure it as an include file. For more
information, see How PSpice uses model libraries and the
companion sidebar on page 4-121 .
