项目编号：048558 PI名称：Massoud， Yehia研究所：William Marsh Rice university题目：互连设计的集成自动化策略：混合信号纳米级集成电路的新范式摘要由于技术的积极扩展和工作频率的增加，互连已成为集成电路中主要的性能限制因素。因此，互连合成在促进当今的混合信号设计中起着至关重要的作用，但目前的设计自动化技术未能将深亚微米互连效应直接纳入合成过程，从而导致昂贵的重新设计。为了促进处理混合信号纳米级集成电路日益复杂的合成策略，PI提出了一种新的互连合成范式，用于评估互连合成过程中电路信号的完整性和性能。在这种新范式下，混合信号系统中的互连被建模、优化和综合，考虑到系统互连的各个方面。这包括模拟互连结构和集成组件，以及互连的数字部分的设计。为了促进和发展我们新的面向系统的混合信号纳米级集成电路互连合成范例，PI将研究和创建：(i)分析建模，优化和合成方法，以促进集成混合信号和片上系统设计的通用设计自动化；（ii）面向系统的互连综合策略，利用统计建模方法结合电感来产生满足设计约束的布局。为了进一步让学生为混合信号互连设计做好准备，PI将在研究生班和本科生班采用动态变化的计算机工程课程，研究生班利用创新的学期项目，强调原创性研究，本科生班强调VLSI设计过程的基础知识，并为学生提供对关键概念的直观理解。

Proposal No: 048558 PI name: Massoud, Yehia Inst.: William Marsh Rice Univ Title: Integrated Automation Strategy for Interconnect Design: A New Paradigm for Mixed-Signal Nanoscale Integrated CircuitsAbstractDue to aggressive technology scaling and increasing operating frequencies, interconnect has become the main performance limiting factor in integrated circuits. Consequently, interconnect synthesis plays a vital role in facilitating today's mixed-signal designs, but current design automation techniques fail to include deep sub-micron interconnect effects directly into the synthesis process, resulting in costly redesign. To promote synthesis strategies that handle the increased complexity of mixed-signal nanoscale integrated circuits, the PI proposes a new interconnect synthesis paradigm that evaluates the circuit signal integrity and performance during interconnect synthesis. Under this new paradigm, interconnect in mixed-signal systems is modeled, optimized and synthesized taking all aspects of the system's interconnect into account. This includes analog interconnect structures and integrated components as well as interconnect in digital portions of the design. To facilitate and develop our new system-oriented interconnect synthesis paradigm for mixed-signal nanoscale ICs, the PI will research and create: (i) analytical modeling, optimization and synthesis methodologies that facilitate generalized design automation in integrated mixed-signal and system-on-chip designs; (ii) system-oriented interconnect synthesis strategies utilizing statistical modeling methodologies incorporating inductance to produce layout that meets design constraints. To further prepare students for mixed-signal interconnect design, the PI will employ dynamically changing computer engineering curriculum in both his graduate class, which utilizes innovative semester-long projects emphasizing original research, and his undergraduate class, which stresses the fundamentals of the VLSI design process and provides students with an intuitive understanding of critical concepts.
