Interconnect has come to be a dominant factor in on-chip signal propagation, skew and jitter. As frequencies increase, more accurate modeling of the wires is necessary in order to properly estimate clock propagation. However, most wire models for clock network synthesis are based on Elmore delay, a simple first-order RC model. In this work, we analyze the discrepancies between RC, RLC and transmission line models on both skew and jitter of clock trees and grids. From our experiments, the difference in skew can be as great as 45% of the clock period for transmission lines and 7.5% for the RLC model. We argue that a deeper investigation into accurately modeling long interconnect should become a higher priority in clock network synthesis
