Breakout Parts
The MicroSim 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.
*. For this device type, the MicroSim libraries supply several breakout parts.
Refer to the online
MicroSim PSpice A/D Reference Manual
for the available symbols.
