A method for reliable measurement of interconnect delays is presented in the paper. The mode of test vectors generation never induces crosstalks. That is why the delay measurement is reliable. Also, minimization of ground bounce noises and reduction of power consumption during the test is an additional advantage. The presented method allows also localizing and identifying static faults of both stuck-at (SaX) and short types. The paper deals with the hardware that is necessary for implementing the method.
