An optimized delay testing technique for LSSD-based VLSI logic circuits

In this paper, an optimized delay testing technique used in level sensitive scan design (LSSD) circuits is described. Methods of improving delay test effectiveness in four different logic groups of six LSSD test chips are illustrated. Comparison of two delay testing measurements using gross strobe timing and per-pin strobe timing are demonstrated in terms of product quality level.<>
