Abstract: We present a statistical based non-tree clock
distribution construction
algorithm that starts with a tree and incrementally insert cross
links,
such that the skew variation of the final clock network is within a
certain
confidence interval under variations in wire width. Monte Carlo
simulations show that the robustness of the final clock network can be
significantly improved with a small increase in wire length.
