    Abstract

    Signalling over long interconnect is a dominant issue in electronic chip design in current technologies, with the device sizes getting smaller and smaller and the circuits becoming ever larger. Repeater insertion is a well established technique to minimise the propagation delay over long resistive interconnect. In deep sub-micron technologies, as the wires are spaced closer and closer together and signal rise and fall times go into the sub-nano second region, the coupling between interconnects assumes great significance. The resulting crosstalk has implications on the data throughput and on signal integrity. Depending on the data correlation on the coupled lines, the delay can either decrease or increase. In this paper we attempt to quantify the effect of worst-case capacitive crosstalk in parallel buses and look at how it affects repeater insertion in particular. We develop analytic expressions for the delay, buffer size and number that are suitable in a-priori timing analyses and signal integrity estimations. All equations are checked against a dynamic circuit simulator (SPECTRE)
