For System-on-Chips (SoCs) the most critical design constraint is power dissipation. Therefore, power aware design should be introduced at early stages of SoC design where it has the highest benefits for power reduction. This also lowers the design complexity and verification effort. Until recently, capabilities to describe and verify the power design early were inadequate which often led to late re-design. Lately, the IEEE 1801 Standard for Design and Verification of Low Power Integrated Circuits, an extension of the Unified Power Format (UPF) was approved. This work uses the new IEEE 1801 standard to describe power aware design. The power design is automatically translated into an executable hierarchy parallel to the system design. Simulation results from system and power design are used to automatically verify the SoC's power aware design against its specifications.
