Highlight

The Highlight tool uses red, green and yellow colors to highlight automatically the failure rate of the components based on their contributions to the overall failure rate of their parent system/assembly. To use this tool, choose System Hierarchy > Tools > Highlight.

The value range of each color is dynamic; it is based on the spread of failure rate values. Red indicates the highest contributors, green indicates less significant contributors and yellow indicates the lowest contributors.

As an example, the following picture shows the contribution of each component to the power supply module. In this example, the main components of the fictional power supply are: AC circuit breaker, power transformer and a printed circuit board (PCB). The Contribution column shows that the PCB accounts for 95.95% of the power supply's overall failure rate. Compared to the contributions of the AC circuit breaker and power transformer, this value is very high; therefore the PCB's failure rate is highlighted in red.

In the PCB assembly, the filter capacitor accounts for 75.21% of the PCB's overall failure rate. This number is high compared to the contributions of the other components in the same PCB assembly; therefore, the filter capacitor's failure rate is also highlighted in red.
