Abstract

Process variation continues to increase with new technologies. With the advent of statistical static timing analysis (SSTA), multiple independent sources of variation can be modeled. This paper proposes a novel technique to reduce variability of metal process variation in SSTA. This novel method maximizes sensitivity cancellation to minimize variability. The developed methodology is simulated with SSTA in 65-nm technology and shows a reduction in variability.
