Embedded systems run the computing devices hidden inside another larger system or product. Embedded systems have the charge of controlling various types of sub-systems; they are also in charge of the monitoring of the whole system and coordination with other systems. This means that when some event affecting the safety of the system occurs, a reconfiguration action is executed in order to maintain the system in a safe degraded state. If the reconfiguration fails then the system will reach a feared (dangerous) state with dramatic consequences for users. So it is important to understand how the system reaches such feared states to set up the reconfiguration actions. In our approach for safety analysis of dynamic systems, feared scenarios are ...
