Abstract
A method for detecting a failure in an electronic signal processing system having a signal processing path comprises a configurable functional unit for performing a given function and at least one redundant version of the signal processing path including a corresponding configurable functional unit for performing the given function and configuring a first operating point for the functional unit in the signal processing path for performing the given function and configuring a second operating point for the corresponding functional unit in the redundant version of the signal processing path. The second operating point is different from the first operating point. The method further comprises applying a same input signal to the functional unit and the corresponding functional unit, comparing a first output signal produced by the functional unit with a second output signal produced by the corresponding functional unit, and deriving a failure indication from the comparing.
