Core Viewpoint - The article discusses the recent news regarding the supply disruption of EDA tools and emphasizes that a complete supply cut is unlikely, as it would signify a decoupling of the semiconductor industries between China and the U.S. The article also highlights the current dominance of three major EDA companies and the challenges faced by domestic EDA firms in China [1][3]. Industry Overview - The EDA industry is relatively small compared to other segments of the semiconductor industry, with the three leading companies—Synopsys, Cadence, and Siemens EDA—holding approximately 70% of the global market share. Synopsys accounts for about 32%, Cadence for 30%, and Siemens EDA for 13% [3][6]. - The largest EDA companies have market capitalizations around $70 billion, with Synopsys projected to generate revenues of $6 billion and net profits of $2 billion in 2024, indicating that EDA is not a high-margin industry [6][3]. EDA Tools and Market Segmentation - EDA tools are categorized into manufacturing EDA and design EDA, with manufacturing EDA being crucial for matching advancements in semiconductor process nodes [9][11]. - The Chinese manufacturing EDA market is expected to reach 4.22 billion yuan by 2028, with a compound annual growth rate (CAGR) of 21.2%, outpacing global growth due to increasing domestic demand [13]. Key Players in EDA - Synopsys has historically maintained a leading position in the EDA market, although it was recently surpassed in market value by Cadence. This shift is attributed to strategic moves, including the former CEO of Cadence joining Intel [15][18]. - Domestic EDA companies, while still lagging behind their U.S. counterparts, are numerous and competitive across various segments. However, only a few are expected to emerge as strong players due to the industry's limited size [19][28]. Domestic EDA Tools - Major domestic EDA companies like Huada Empyrean and others have developed comprehensive tools for analog IC design and wafer manufacturing, covering a wide range of processes [20][22]. - Despite the presence of domestic alternatives, there are significant gaps in quality and reliability compared to established foreign tools, leading many companies to prefer more expensive foreign solutions to mitigate risks [28][29].
