以下文章来源于傅里叶的猫 ，作者小小 傅里叶的猫 . 芯片EDA大厂资深工程师，半导体AI行业解读及研报分享 这两天EDA断供的事传的沸沸扬扬，金融时报和路透社都报道了这件事。截止到目前，最新的消息还 是这两个报告中的内容，但还不知道具体的细节。笔者认为全面断供即一刀切的可能性并不是很大，这 样就基本意味着中美半导体产业的脱钩。 虽然我们目前都在讲国产替代，但还是要正视跟美国的差距，目前全球三大家EDA公司：Synopsys、 Cadence和西门子EDA（被收购前叫Mentor）还是处于垄断地位，国内绝大多数的芯片设计公司依然是 使用这三家的工具和IP，这篇文章我们来分析一下EDA这个行业，以及国产EDA都覆盖了哪些方面。 本文中的很多图片和数据参考自沙利文的研报和知识星球"半导体综研"中的统计内容。 EDA行业的规模并不大 其实对于很多非芯片行业的人，可能都听过英伟达、Intel、AMD、高通芯片这种设计公司，除了Intel， 其他几家都是Fabless，也就是只设计，没有foundry；肯定也听过台积电、中芯国际、华宏这种foundry 公司，但却很少有人听过Synopsys（新思）、Cadence和M ...

Core Viewpoint - The A-share EDA (Electronic Design Automation) companies experienced a significant stock price increase, indicating a positive market sentiment towards the sector amid ongoing developments in the industry [1]. Industry Overview - The EDA industry is highly concentrated, dominated by three major players: Cadence, Synopsys, and Siemens EDA, which hold a significant competitive advantage [4]. - Chinese companies like Huada Jiutian, Gai Lun Electronics, and Guangliwei are emerging as key players, with Huada Jiutian focusing on comprehensive digital EDA solutions, Gai Lun Electronics specializing in analog circuit design, and Guangliwei concentrating on EDA verification tools [5][6]. - The domestic EDA market is witnessing a push for localization, driven by the need for independent EDA tools due to restrictions on software access [4]. Mergers and Acquisitions - The trend of mergers and acquisitions is prevalent in the EDA industry, with nearly 300 acquisitions occurring over the past 30 years, highlighting the importance of consolidation for growth [5]. - Huada Jiutian and Gai Lun Electronics have initiated their own acquisition strategies to enhance their capabilities and market position [6]. - Gai Lun Electronics' acquisition of Ruicheng Semiconductor is expected to strengthen its IP layout and improve product development efficiency [6]. Competitive Landscape - The primary gap between domestic EDA firms and international leaders lies in the lack of a full-process capability and weaknesses in certain areas, such as system-level EDA tools and high-end IP library development [7]. - The domestic EDA companies are expected to gradually catch up in specific segments, but overall integration and consolidation will be necessary to close the gap with global leaders [7].
