Abstract
An enhanced delay test generation procedure for high-speed logic LSIs is presented. The procedure is applicable to general scan-designed sequential circuits including both level-type flip-flops and edge-type flip-flops. Some techniques are introduced to solve the problem of `same-clock signal transfer´ between these flip-flops and to enhance the performance of the delay test generation procedure. The effectiveness of the procedure is demonstrated by the experimental results obtained
