摘要：

In this paper we present and carefully analyze a transition energy cost model aimed for efficient power estimation of performance critical deep submicron buses. We derive an accurate transition energy cost matrix, scalable to buses of arbitrary bit width, which includes properties that closer capture effects present in high-performance VLSI buses. The proposed energy model is verified against Spectre simulations of an implementable bus, including drivers. The average discrepancy between results from Spectre and the suggested model is limited to 4.5% when fringing effects of edge wires is neglected. The proposed energy model can account for effects that limit potential energy savings from bus transition coding.
