Estimation and bounding of energy consumption in burst-mode control circuits

This paper describes two techniques to quantify energy consumption of burst-modeasynchronous(clock-less)controlcircuits. The circuit specifications consideredare extended burst-mode specifications, and the implementations are multi-level logic implementations whose outputs are guaranteed to be free of any voltage glitches (hazards). Both techniques use stochastic analysis to combine a small number of simulations in order to quantify average energy per external signal transition. The first technique uses N-valued simulation to derive mathematically tight upper and lower bounds of energy consumption. Using this technique we bound the effect of hazardsunderall possible operating conditions and environments for a given circuit. Additionally, to drive synthesis tools for low-power, we proposea second technique that uses fixed-delay simulation to derive a realistic estimate of energy consumption within our derived upper and lower bounds. We demonstrate the feasibility of both these tech...
