1. An arrangement for testing an integrated circuit comprising at least two circuit sections ( 1, 2 ) which in normal operation operate with at least two different clock signals, characterized in that the integrated circuit to be tested is formed in such a way that each clock signal can be individually switched on and off during a test by test software provided in the arrangement, in that a software model of the circuit to be tested is provided in the arrangement, which software model comprises an X generator ( 38, 40 ) for those circuit components ( 33, 35 ) whose mode of operation is influenced by a plurality of clock signals and their skew behavior, which X generator is activated and supplies an X signal when more than one clock signal influencing the mode of operation of the circuit components ( 33, 35 ) during testing is activated, in that, during testing, the test software initially activates all clock signals and evaluates test results for those circuit components ( 3, 5 ) for which no X signal appears in the software model ( 33, 35 ), and in that for those circuit components ( 3, 5 ) for which an X signal appeared in the software model ( 33, 35 ) during testing with all clock signals, the test software performs a plurality of test runs in which each time only one or more of the clock signals influencing the mode of operation of the circuit component ( 3, 5 ) is/are activated and evaluates only those tests of the circuit components ( 3, 5 ) of the circuit for which no X signal appears in the software model ( 33, 35 ).
