Abstract :
A new diagnosis method for combinational circuits is proposed which is a modification of traditional signature analysis. By this method, instead of a technical fault the first erroneous test response in the presence of the considered fault is determined. Additionally to the accumulated signature a one-dimensional output sequence of the MILFSR is monitored during test and diagnosis. Some of the test inputs have to be repeatedly applied for diagnosis
