Fault Tree Editor

Fault Tree Analysis (FTA) presents the sequence of events leading to an end-effect

(Top Event) selected. FTA is a top-down approach which involves selecting a system

failure (Top Event), compared to a Failure Modes and Effects Analysis (FMEA) which

is bottom-up approach where failure paths are traced from their original cause through

the system to the nominated end-effect. FTA identifies all failure paths that can

potentially lead to the Top Event.

1. Select and enable the RAM module
2. Right-click an item of interest from the System Model editor or Project Explorer viewer
