Siemens(US:SIEGY) 半导体行业观察·2025-09-27 01:38Core Viewpoint - Automotive chips are essential for the development of electric and intelligent vehicles, facing challenges such as high reliability requirements, large-scale circuit verification, and stringent functional safety standards [2][14]. Group 1: Quality, Safety, and Reliability Challenges - Automotive chips must meet high-quality testing and zero-defect (0 DPPM) requirements, eliminating defects introduced during manufacturing [4]. - The verification cycle for automotive-grade chips is longer than for consumer-grade chips, requiring rigorous testing certifications like AEC-Q100, which increases design cycle and cost challenges [4]. - The complexity of fault types and testing scales has increased with the development of large-scale integrated circuits, leading to higher testing difficulty, time, and costs [4]. Group 2: Testing Solutions - Siemens EDA's Tessent™ solution helps automotive chip designers ensure high quality, enhance safety, and improve reliability, accelerating time-to-market [4]. - Tessent DFT technology provides high-quality testing to ensure zero defects, generating defect-oriented fault models for comprehensive testing coverage [5]. - Tessent™ LogicBIST and MemoryBIST solutions enable in-chip self-testing capabilities and non-destructive memory testing during system operation, respectively [8]. Group 3: Verification Challenges - Accurate functional verification before chip tape-out is crucial, with increasing complexity in automotive chips making this process more challenging [10]. - The new Veloce™ CS hardware-assisted verification system from Siemens EDA significantly enhances hardware acceleration performance, supporting over 40 billion gates [11]. - Veloce proFPGA CS allows for rapid execution of silicon verification, facilitating firmware and application development [12]. Group 4: Functional Safety Requirements - The performance and safety of chips directly impact driving safety, necessitating compliance with functional safety standards like ISO 26262 [14]. - There is a growing demand for higher safety levels in automotive chips, particularly for ASIL-D level designs related to advanced driver-assistance systems (ADAS) [15]. - Siemens EDA's Austemper platform enhances efficiency in safety analysis and verification, supporting clients in meeting ASIL-B and ASIL-D requirements [15][17]. Group 5: Industry Impact - Automotive chips play an indispensable role in the intelligent and electric transformation of modern vehicles, with Siemens EDA providing advanced solutions to ensure high quality and reliability [17].
