传长鑫和长存启用国产EDA！

Core Viewpoint - The article emphasizes the shift in focus towards domestic electronic design automation (EDA) tools in the semiconductor industry, driven by the increased production capacity of Changxin Memory and Yangtze Memory Technologies, aiming to reduce reliance on foreign technologies [1][5]. Group 1: DRAM Production - Changxin Memory's DRAM production capacity is expected to experience explosive growth by 2025, with monthly output increasing from 100,000 wafers in 2024 to 200,000 wafers, totaling an annual output of 2.73 million wafers [3]. - The collaboration with domestic EDA companies like Huada Jiutian has enabled a fully localized support system from design to mass production, enhancing competitiveness against international manufacturers [3]. Group 2: NAND Flash Production - Yangtze Memory's first fully domestic trial line for NAND flash is set to begin production in the second half of 2025, targeting a global market share of 15% by 2026 [4]. - The introduction of self-developed technologies and domestic equipment has led to the mass production of the 294-layer X4-9070 chip, achieving an interface speed of 3600 MT/s [4]. Group 3: EDA Tool Development - Despite the temporary lifting of U.S. export restrictions on EDA tools in July 2025, the urgency for self-sufficiency in the industry has been recognized [5]. - Companies like Hejian Software are rapidly innovating to meet market demands, with their new generation of hardware systems significantly enhancing verification capabilities [5]. - The domestic EDA market is projected to reach 14.95 billion yuan by 2025, with an expected localization rate of 17% [5]. Group 4: Market Dynamics - The global EDA market is still dominated by three major players—Synopsys, Cadence, and Siemens—holding over 80% market share, making it challenging for domestic tools to compete in the short term [6]. - Chinese companies are adopting a collaborative innovation model to overcome barriers, focusing on the integration of EDA tools and foundational software [6]. - The evolution from point tools to comprehensive process coverage signifies a transition of the Chinese EDA industry from a replacement phase to an innovation phase, supporting the country's shift from a "manufacturing giant" to a "design powerhouse" [6].
