A simulation method of development processes of LSIC element failures, based on the introduction of surface acoustic waves (SAW) into a semiconductor chip with supply voltage and electric test actions applied simultaneously is proposed. It is shown that the degradation process intensification is achieved due to the increase of the degree of the state nonequilibrium of crystal lattice atoms resulting in the decrease of the threshold energy necessary for their participation in the degradation process. An analytical expression allowing the evaluation of test regimes, and, in the first place, the SAW amplitude, ensuring carrying out the test for a given period of time has been obtained. A test cell, the test results are given.
