ABSTRACT:
Integrated module having a circuit and a plurality of input/output terminals, each of the input/output terminals being connected to a driver circuit for driving output signals and to a reception circuit for receiving input signals, a first delay element with a first delay time being provided in the integrated module, which delay element can be connected into a signal path of a circuit-internal signal or can be disconnected, in order to delay or to accelerate the circuit-internal signal, wherein provision is made of a first test delay element at a first input/output terminal pair which is embodied in a manner structurally identical to the first delay element, in order, in a test operation, to determine the delay time by means of the signal propagation time between the two input/output terminals of the first input/output terminal pair.
