Impacts of signal slew and skew variations on delay uncertainty and crosstalk noise in coupled RLC global interconnects

This paper addresses the impacts of signal slew time and signal skew variations on delay uncertainty and cross talk noise in coupled inductive lines for different switching patterns. Our findings reveal that delay variation in a victim line always increases with the reduction of signal slew time and increase in signal skew. We also observe that cross talk noise reduces with increasing signal skew, and the impacts of skew variation on cross talk noise is more prominent for lines with strong capacitive coupling. Here, equivalent circuit model parameters have been extracted using FastCap and FastHenry field solvers, and results have been obtained by HSpice simulation.
