System-level design for heterogeneous integrated systems

2007年的IF ITRS(国际半导体技术路线图)强调了“比摩尔定律更重要”的运动。这一运动的重点是系统集成，而不是晶体管密度，并将导致集成系统的功能多样化。这种多样化允许诸如RF、功率控制、光学和/或机械部件、传感器和致动器等非数字功能从系统板级迁移到封装级(SiP)或芯片级(SoC)实现。这些不同的系统将使新的应用成为可能，并打开新的市场。它们将出现在交通、安全、卫生、能源等关键领域。然而，这些异质系统的设计仍然是一个挑战，需要在技术、体系结构和系统层面进行更多的研究。为了克服系统级设计的复杂性，需要一种集成的分层设计方法。这种类型的设计意味着通过综合和改进进行建模和优化的几个阶段。

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.
