The Running Example: The Windshield-Wiper ECU

One modest system, carried from function to finished tree.

The windshield-wiper control ECU is placed in the context that requires it and then examined from the inside, as a system of subsystems along an internal signal path. The example is deliberately simple, so its trees never grow past the point where their structure can still be seen. The block diagram is not an illustration but the ibd the fault tree is derived from.
