## About

Based in Shanghai, China, and founded in 2010, Primarius Technologies Co., Ltd., trading as Primarius, is a full-process EDA solution provider dedicated to creating application-driven EDA solutions covering integrated circuit design and manufacturing, providing products such as manufacturing EDA, general analog design EDA, digital design EDA, and IP design. Headquartered in Shanghai, with offices in Beijing, Silicon Valley, and Seoul, the company serves tier-one foundries, memory manufacturers, and semiconductor companies worldwide. Primarius focuses on bridging IC design and manufacturing through advanced process development, enabling higher yield, enhanced performance, and stronger competitiveness for semiconductor enterprises. In August 2026, SDIC Venture Capital and Hubei Railway Development Fund acquired 26.98 million shares in Primarius at CNY 38,92 apiece for approximately CNY 1.05 billion, in a PIPE transaction.

The company offers solutions across four business segments: design EDA, fab EDA, testing solutions, and engineering services. Its design EDA products include universal parallel SPICE simulators, large-capacity and high-precision SPICE simulators, dual-solver fast SPICE simulators, mixed-signal simulation tools, yield-oriented design platforms, waveform viewers, and hierarchical SoC design planning solutions. Its fab EDA offerings cover advanced SPICE modeling platforms, intelligent model extraction tools, cross-platform modeling software, process and design verification platforms, parametric cell library development, and PDK verification systems. The company’s testing solutions include all-in-one semiconductor parameter analyzers and low-frequency noise measurement systems, while its engineering services provide advanced wafer testing platforms and semiconductor engineering solutions that support high-end chip R&D.

Primarius generates revenue primarily through software licensing, engineering services, and system integration for semiconductor design and manufacturing customers.

The transaction in August 2026 will enable Primarius to strengthen its capital base, optimize its capital structure, enhance its risk resilience, and provide funding support for future development.
