The rapid development of hardware/software and microelectronic technology enables the realization of more complex systems with new characteristics. These characteristics could lead to further advances in electronic measurement-, control- and regulation systems. The industrial demands of future electronic systems rely on systems to be fault-tolerant, since the complexity will increase to the point where it is impossible to detect all errors during the design phase.

The ability for a system to recover from a failure requires that incorrect system operation can be detected and analysed during run-time. To achieve this, methods for performing tests of functionalities and components dynamically must be incorporated in the system behaviour during the design phase.

This paper presents methods for efficient on-line failure detection, integrated in a reconfigurable system for execution and test of multiple automotive inner cabin functions. These methods also allow a certain degree of failure recovery, and even make it possible for a system to heal itself from more advanced faults. By exploiting the ability of dynamic and partial hardware reconfiguration, the monitoring can also be performed with less hardware overhead since the monitoring functionalities are configured only when they are required.
