Breakout parts
The OrCAD libraries supply passive and semiconductor
parts with default model definitions that define a basic set
of model parameters. This way, you can easily:
• assign device and lot tolerances to model parameters
for Monte Carlo and sensitivity/worst-case analyses,
• define temperature coefficients, and
• define device-specific operating temperatures.
These are called breakout parts and are summarized in the
following table.
