Analog/RF circuits have been recognized as the design bottleneck for getting System-on-Chip products to market due to the high sensitivity to the associated analog/RF effects and the limited availability of analog/RF computer-aided design (CAD) tools. In particular, so far most of analog/RF layouts have to be handcrafted by circuit designers. Thus, the layout-related constraints are hard to be satisfied and included in the circuit synthesis. In this proposal, the development of design methodology and CAD tools for robust circuit/layout synthesis of analog/RF integrated circuits in deep-submicron and nano technologies is proposed. This work will focus on setting up complete circuit synthesis flow, investigating performance-driven automatic layout generation, fully taking into account distinct manufacturability issues in the advanced technologies, and exploring layout automation aided by circuit tuning. This will be the first fully automated manufacturability- aware performance-driven layout-centric synthesis methodology for analog/RF integrated circuits. In the circuit synthesis flow, the layout automation is integrated. Circuit tuning takes into account the layout-related effects so that circuit topology and sizing can be refined. The proposed complete layout design flow is composed of automatic template generation and template-based compaction. We will develop a new template-based scheme based on the macro-cell layout approach to facilitate the intellectual property reuse. Thus, the generated layout is reliable in the sense of performance and manufacturability without compromising the design efficiency.

由于对相关模拟/RF效应的高灵敏度以及模拟/RF计算机辅助设计（CAD）工具的有限可用性，模拟/RF电路已被认为是使片上系统产品进入市场的设计瓶颈。特别是，到目前为止，大多数模拟/RF布局必须由电路设计人员手工制作。因此，布局相关的约束很难被满足，并包括在电路综合。在这一建议中，提出了在深亚微米和纳米技术中开发用于模拟/RF集成电路的鲁棒电路/布局合成的设计方法和CAD工具。本研究的重点是建立完整的电路综合流程，研究性能驱动的自动版图生成，充分考虑先进技术中的可制造性问题，并探索电路调整辅助的版图自动化。这将是模拟/RF集成电路的第一个全自动可制造性感知性能驱动的以布局为中心的综合方法。在电路综合流程中，集成了版图自动化。电路调整考虑到了与布局相关的影响，因此可以优化电路拓扑和尺寸。完整的版图设计流程包括自动模板生成和基于模板的压缩。我们将根据宏单元布局方法开发一种新的基于模板的方案，以促进知识产权的重用。因此，所生成的布局在性能和可制造性的意义上是可靠的，而不损害设计效率。
