    摘要: A circuit arrangement comprising a logic circuit to be tested and a test circuit is provided. The logic circuit is designed to provide output data from input data, said output data being generated from the input data by logic-circuit-internal combinations, such that the output data are in a predetermined relationship with the input data. The logic circuit is designed to detect whether the relationship is fulfilled and to provide an error signal if the relationship is not fulfilled. The test circuit is designed to alter logic-circuit-internal combinations. The test circuit is designed to detect the error signal, and is furthermore designed to output an alarm signal if the error signal is not detected upon alteration of the logic-circuit-internal combinations.
