“…This is often still not the case for anything other than benchmark examples. Piguet [1989] reports that due to the use of design automation the transistor density normalized to minimum feature size has decreased significantly over the years, indicating less efficient use of silicon. Experience from the high-volume embedded controller market shows that efficiencies within 20% of manual designs are needed to successfully introduce automatic compilation techniques.…”

In this article we provide a practical transformational approach to the synthesis of correct synchronous digital hardware designs from high-level specifications. We do this while taking into account the complete life cycle of a design from early prototype to full custom implementation. Besides time-to-market, both flexibility with respect to target architecture and efficiency issues are addressed by the methodology. The utilization of user-selected behaviorpreserving transformation steps ensures first-time-right designs while exploiting the experience, flexibility, and creativity of the designer.To ensure that design transformations are indeed behavior-preserving a novel mechanized approach to the specification and verification of design transformations on control data flow graphs which is independent of a specific behavioral model or graph size has been developed.As a demonstration of an industrial application we use a video processing algorithm needed for the conversion from a line-interlaced to progressively scanned video format. Both a video signal processor-based prototype implementation as well as a very efficient full custom implementation are developed starting from a single high-level behavioral specification of the algorithm in VHDL. Results are compared with those previously obtained using different tools and methodologies.
