Correlation Table Template

To propagate failure modes using a correlation table, you need a template to define the correlation table. This table defines how the propagation works.

You also need to define a template for the FMEA table, which is linked with the correlation table.

The following examples present the propagation of failure modes using a correlation table in the case of testability analysis.
