System-level design for heterogeneous integrated systems

The 2007 edition if ITRS (The International Technology Roadmap for Semiconductors) emphasizes the "More Than Moore's Law" movement. This movement focuses on system integration rather than transistor density and will lead to a functional diversification in integrated systems. This diversification allows for non-digital functionalities such as RF, power control, optical and/or mechanical components, sensors and actuators to migrate from the system board level into a package level (SiP) or chip level (SoC) implementation. These heterogeneous systems will enable new application and open new markets. They will be found in key domains like transport, security, health, energy. However, the design of these heterogeneous systems is still a challenge and more research is required at the technological, architectural and system level. An integrated hierarchical design approach is needed to overcome the system-level design complexity. This type of design implies several stages of modeling and optimization through synthesis and refinement.
