The power consumption of battery-powered and energy-scavenging devices has become a major design metric for embedded systems. Increasingly complex software applications as well as rising demands in operating times while having restricted power budgets make power-aware system design indispensable. In this paper we present an emulation-based power profiling approach allowing for real-time power analysis of embedded systems. Power saving potential as well as power-critical events can be identified

... in much less time compared to power simulations. Hence, the designer can take countermeasures already in early design stages, which enhances development efficiency and decreases time-to-market. Accuracies achieved for a deep submicron smart-card controller are greater than 90% compared to gate-level simulations.
