SoC System-Level Design Methods and Techniques

A comprehensive survey on main research topics in the area of Y-chart SoC system level is introduced. Three catalogs of research aspects, including hardwaresoftware co-design, design reuse and high-level design with physical information, are discussed in detail. From the view point of design methodologies and techniques, present system-level design work are summarized into the following three design approaches: SpecC-based design methodology (from top to down and stepwise-refinement), component-based multi-processor SoC design methodology (from bottom to up and building block), and platform-based design methodology (meeting-in-the-middle and divide-and-conquer). Based on these generally accepted achievements, the relevant fundamental ideas, specification languages, design models and key techniques are also analyzed and compared in this survey. Some open research issues in the system-level design area are pointed out, and some future research directions are presented.
