Abstract
The invention relates to a method for testing electrical modules. A test pattern of input signals is applied to each module to be tested as test specimen, and the actual responses of the test specimen to the test pattern is compared with the desired responses. The comparison result is evaluated for the purpose of displaying test assessments. According to one embodiment of the invention, to supply the desired responses, a reference module produced with the same design and technology as the test specimen and tested as entirely satisfactory is utilized. The same test pattern as for the test specimen is applied to the reference module. The invention furthermore relates to circuit arrangements for carrying out this method, in particular for testing data memories.
