The Lambda Chart: A Model of Design Abstraction and Exploration at System-Level
Falko Guderian, Gerhard Paul Fettweis · 2011
Abstract—In recent years, chip design complexity is further increasing through multi-processor system-on-chip built up from macro blocks. System-level design promises to close the growing productivity gap between hardware and software design but more sophisticated design models are needed. Therefore, we developed a new model of system-level design abstraction. Therein, three views divide the design space to reduce design complexity. A unified design process with five steps has been defined for the design views. Furthermore, we show that the model is able to formalize system-level design exploration. Finally, exploration has been considered as walk through the design views connected via inter-view links. With the proposed system-level model, the authors provide conceptual foundations to more holistic design and introduce formalization of design exploration.
