Abstract
In a method and device measuring a delay time of a section of a digital circuit, an output signal of the section is saved in different memory locations with a clock and earlier by a time interval with respect to the clock, different durations being assigned to the time interval. The delay time is determined as a function of the greatest of the different durations during which a test proceeds in a positive manner. The test proceeds in a positive manner if the value saved with the clock corresponds with the value saved so as to be earlier by the corresponding time interval.
