摘　　要：左移(shift-left)融合是电子设计自动化(electronic design automation,EDA)的一种新设计范式,旨在通过融合和并行解决传统瀑布式设计范式的问题.传统EDA流程分为多个串行设计阶段,导致设计周期长、设计冗余大.通过相邻设计阶段的融合与并行,可以有效缩短设计周期、提升设计优化效率.左移融合通常涉及在不同设计阶段之间共享数据模型,并采用新的抽象方法,可以应用到包括高层次综合、逻辑综合、布局布线、签核验证、工艺优化等EDA流程的各个阶段.此外,借助早期的数据分析与评估,可以有效应对后期可能出现的问题,从而降低开发成本.综上,鉴于左移融合对于提高EDA流程的效率和质量具有重要意义,本文将介绍左移融合的发展现状和关键科学问题,并展望未来发展路线.ion that can be applied to various stages of EDA flow,including high-level synthesis,logic synthesis,placement and routing,verification,process optimization,etc.In addition,with the help of early data analysis,possible problems in the late stage can be identified and addressed early,thereby reducing development and verification costs.In summary,left shift and fusion are of great importance for improving the efficiency and quality of the EDA flow.This paper will introduce and discuss the progress and challenges of the left-shift and fusion paradigm and look forward to the potential frontier research directions recommended to the National Natural Science Foundation of China.
