Setting Up An Analysis
Check Safe Operating Area Analysis
performance. Other mechanisms, which cause sudden and complete damage of the device, (like
the oxide breakdown for example) are not targeted in this scope.
Reliability changes can be analyzed for the following degradation effects:
• Hot-Carrier Injection (HCI).
• Negative Bias Temperature Instability (NBTI) degradation.
• Other stress effects can be modeled.
Aging and reliability analysis enables a comparison of the fresh and degraded (aged) waveforms
to see how much impact the degradation has on circuit performance. It is then possible to
determine which device parameter is primarily responsible for degradation and identify the
most sensitive part of the circuit.

Check Safe Operating Area Analysis
The .CHECKSOA command checks for any violations of the circuit safe operating area (SOA)
limits. The safe operating area limits are set for device parameters, model parameters, and Eldo
expressions using the .SETSOA command.
