Abstract :
As CMOS technology scales down, the coupling capacitance between adjacent wires plays dominant part in wire load and interference becomes a serious problem for VLSI design. In this paper, we focus on delay increase caused by adjacent lines. This increase in delay due to coupling can have a dramatic impact on IC performance for deep submicron technologies. We propose an analytical expression to compute the delay in the presence of coupling that takes explicitly into account interconnect resistance and capacitance, driver resistance and relative driver strengths
