ATICA4CAPELLA metamodel allows to define safety features at different levels of the system architectural layers. The following picture presents the association relationships between different elements available in the model based safety analysis plugin.

The Fault Tree module (and cut set calculator) allows to evaluate the system implementation from a safety perspective. Using the Failure Conditions defined at System Analysis level as reference (see also FHA), the Fault Tree analysis module allows to identify the combination of lower level failure modes (linked to physical constituents of the system) that may provoke a Failure Condition.
