Statistical based link insertion for robust clock network design

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.
