Applicable to both unit logic cells supplied by the integrated circuit vendor and logical macros defined by the integrated circuit designer. Its application applies equally well to representation of timing and power for designer defined macros, although this specification is written towards the integrated circuit supplier and EDA developer.

The scope of the DPCS standard is to make it possible for integrated circuit designers to analyze chip timing and power consistently across a broad set of EDA applications, for integrated circuit vendors to express timing and power information once (for a given technology), and for EDA vendors to meet their application performance and capacity needs.
