Abstract :
We present a comprehensive mathematical analysis of the energy dissipation in deep submicron technology buses. The energy estimation is based on an elaborate bus model that includes distributed and lumped parasitic elements that appear as technology scales. The energy drawn from the power supply during the transition of the bus is evaluated in a closed form. The notion of the transition activity of an individual line is generalized to that of the transition activity matrix of the bus. The transition activity matrix is used for statistical estimation of the power dissipation in deep submicron technology buses.
