Scan Cell Ordering for Low Power Scan Testing


Power consumption during scan testing is becoming a primary concern. In this paper, we present a novel approach for scan cell ordering which significantly reduces the power consumed during scan testing. The proposed approach is based on the use of a two steps heuristic procedure that can be exploited by any chip layout program before flip-flops placement and routing. The proposed approach works for any conventional scan design and offers numerous advantages compared with existing low power scan techniques. Reductions of average and peak power consumption during scan testing are up to 34% and 18% respectively for experimented ISCAS benchmark circuits.
