This standard defines the syntax and semantics of a format used to express power intent in energy-aware electronic system design. Power intent includes the concepts and information required for specification and validation@ implementation and verification@ and modeling and analysis of power-managed electronic systems. This standard also defines the relationship between the power intent captured in this format and design intent captured via other formats (e.g.@ standard hardware description languages and cell libraries). Purpose The standard enables portability of power intent across a variety of commercial products throughout an electronic system design@ analysis@ verification@ and implementation flow.
