Statistical static timing analysis (SSTA) is ideal for random variations but is not suitable for environmental variations like Vdd and temperature. SSTA uses statistical approximation, according to which circuit timing is predicted accurately only for highly probable combinations of variational parameters. SSTA is not able to handle accurately deterministic(More)
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.(More)
Technology trends show the importance of modeling process variation in static timing analysis. With the advent of statistical static timing analysis (SSTA), multiple independent sources of variation can be modeled. This paper proposes a methodology for modeling metal interconnect process variation in SSTA. The developed methodology is applied in this study(More)
