Information

This is a model of an operational amplifier. It shows how to combine reliability information and Modelica models.

Reliability Information

The annotations are edited in the reliability view. Here a reliability block diagram is created by selecting "ReliabilityDistribution" from the Distribution drop-down menu, and a series connection has been entered in the Parameters text field.

IndividualReliabilityParameters_normal

The individual components have their own reliability information. This model is using the same components as Amplifier but with higher failure rates, as it is operating at a higher temperature.
