As integrated circuit technologies advance toward higher performance, greater densities, and increasing system complexity, CAD tools and design methodologies struggle to keep pace. Managing the formidable complexity of the design process is one of the main challenges to IC design. Disseminating design reuse is central to bringing the design effort's complexity back to a manageable size. Effective reuse, though, takes more than just gathering predesigned components in a library. Reuse-oriented policies and strategies must permeate the entire design process, from the methodologies themselves to the final designs.In this article, we provide a brief overview of the state of the art in design reuse for digital systems. We also discuss the challenges posed to this discipline by the recent trend toward integrating processor cores in high-volume application-specific integrated circuits.Design reuse, particularly in the core-based system-on-chip (SOC) design era, is no longer a discipline in isolation. Reuse cannot be fully separated from simulation and verification, estimation, synthesis, or test. For example, the "Design Section" of the 1999 edition of the International Technology Roadmap for Semiconductors emphasized the need for synthesis technology to support the reuse of predesigned General-purpose VHDL-based reuse Preis et al. proposed a domain-independent, VHDL-based reuse methodology for a hypertextbased reuse environment. 2 At the core of this A Survey of Digital Design Reuse Design Reuse 98 The authors survey recent advances in digital design reuse. They stress the need for effective strategies that accommodate reuse throughout the entire design process.
