Performance-Driven CAD Tools for Asynchronous Circuits

异步设计是同步设计的一种有吸引力的替代方案，因为它们没有时钟偏差问题、可能出现平均情况下的延迟、对物理特性的适应性以及节能。该项目专注于性能分析和性能驱动综合的技术，这些技术结合起来可以促进高性能异步电路的设计。对于性能分析，研究人员正在探索分析和基于模拟的分析技术，这些技术可以指导架构设计，并指导控制器综合工具针对用户指定的系统性能指标进行优化。为了进行综合，这项研究正在利用现有的技术映射工具，该工具使用最少的系统信息来识别并优化常见的过渡。通过增加可用的系统信息量，可以优化选定的关键过渡。在这些设计中，常见的转换不一定是关键的和关键的

Asynchronous designs are an attractive alternative to synchronous designs due to their lack of clock skew problems, potential for average-case delays, adaptability to physical properties, and power savings. This project focuses on techniques for performance-analysis and performance- driven synthesis that together can facilitate the design of high-performance asynchronous circuits. For performance analysis, the investigator is exploring analytical and simulation-based analysis techniques that can guide architectural design as well as guide controller synthesis tools to optimize for user-specified system performance metrics. For synthesis, the research is leveraging off an existing technology mapping tool that uses minimal system information to identify and then optimize common transitions. By increasing the amount of system information available, selected critical transitions can be optimized. In these designs common transitions need not be critical and critical
