Abstract :
A novel method for introducing online test facilities in a controller with a very low overhead is presented. This online test consists of detecting illegal paths in the control flow graph. These illegal paths may be due to either permanent faults or transient errors. The implementation of the detection facilities relies on a clever choice of the state codes of the controller, which can then be checked by signature analysis by either a built-in monitor or an external checker
