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

异步设计是同步设计的一个有吸引力的替代方案，因为它们没有时钟偏移问题，平均情况下的延迟潜力，对物理特性的适应性和功耗节省。本计画着重于效能分析与效能驱动综合的技术，两者结合可促进高效能非同步电路的设计。对于性能分析，研究人员正在探索分析和基于仿真的分析技术，可以指导架构设计以及指导控制器合成工具，以优化用户指定的系统性能指标。对于综合，该研究利用了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转换。通过增加可用的系统信息量，可以优化选定的关键转换。 在这些设计中，常见的过渡不需要是关键的和关键的
