Abstract-- Process variation has more significant impact
on circuit performance as technology develops to nano
scale. It is therefore necessary to evaluate chip performance
using statistical timing analysis rather than deterministic
static timing analysis. This paper first evaluates the impact
of single extrinsic fluctuation on circuit performance based
on the rigorously derived propagation delay model. The
parameter fluctuations are characterized and a novel
statistical approach is developed to evaluate the effect of
