Abstract :
An efficient yet accurate model for determining the power consumption of mux-based crossbar interconnects is presented. First, an analytical model for the power consumption of a cell in the crossbar interconnect is introduced. The model is based on the modified n-th power law which is suitable for short channel MOSFET I-V characteristics. Using the cell model, as well as input and control signals, an analytical expression for the power consumption of the whole interconnect is presented. The proposed model is compact and scalable making it suitable for power estimation CAD tools. The results of the proposed model for a current and predictive CMOS technology show an excellent accuracy in comparison with the results of HSPICE simulations.
