Xinxiao Technology's New Tool Slashes Chip Power Sign-off Time from Weeks to Days
Chinese startup Xinxiao Technology has developed a high-performance distributed solution to significantly reduce the time required for chip power sign-off, a critical final step in chip design. This process, analogous to a final inspection of a building's power system, involves analyzing billions of nodes in the power network to assess power consumption, voltage drop, and electromigration. Traditionally, this complex analysis, which involves solving massive sparse matrix equations, could take several weeks. As chip manufacturing processes shrink and transistor counts increase exponentially, this sign-off period has become a bottleneck, often necessitating design revisions and repeated sign-off cycles.
Xinxiao Technology's new digital power sign-off tool, "IcPower," utilizes distributed matrix solving techniques derived from computational mathematics. By breaking down the enormous matrices into smaller, manageable sub-matrices that can be processed in parallel across multiple computers, the tool dramatically accelerates the analysis. The company claims IcPower is 4.5 to 8.5 times faster than existing tools from major international EDA vendors in typical test cases and can complete tasks in days that previously took weeks. This innovation addresses a key pain point in the industry, aiming to speed up chip delivery.
The company is also leveraging the trend of "domestic substitution" in China's EDA market, which has historically been dominated by global giants like Synopsys, Cadence, and Siemens EDA. Xinxiao Technology's business model involves software licensing with pricing comparable to international tools. IcPower is already in use at several Chinese chip manufacturers for CPUs, GPUs, and intelligent driving chips. Looking ahead, Xinxiao Technology plans to expand its product line to include thermal and stress analysis tools to support 3D chip designs and is exploring AI integration for a more intuitive chip design platform. The company aims to achieve several million yuan in revenue by 2025 and plans a new round of financing in late 2026 to support market expansion.
The development by Xinxiao Technology addresses a significant bottleneck in advanced semiconductor manufacturing, where the computational complexity of power sign-off has outpaced traditional methods. By applying distributed computing principles, the company offers a potential solution to accelerate chip development cycles, aligning with the industry's drive for faster innovation. This advancement is particularly relevant as chip designs become more complex, pushing the limits of Moore's Law and necessitating new approaches to verification. The company's focus on domestic substitution within the EDA market highlights geopolitical influences on technological development, creating opportunities for local players. However, sustained growth will depend on the ability to scale operations, build trust with customers regarding product longevity, and continue technological innovation in areas like AI-driven design and thermal management for advanced packaging, all within an increasingly competitive global landscape.
