About NanGate

NanGate was a specialized firm in the Electronic Design Automation (EDA) sector, focusing on software and physical library Intellectual Property (IP) for semiconductor design. The company was established in October 2004 by a team of seasoned semiconductor professionals with prior experience at companies like Intel Corporation and Vitesse Semiconductor Corp. Key founders included Ole Christian Andersen, who served as President and CEO since the company's inception, Jens P. Tagore-Brage as CTO, and Jens C. Michelsen as COO.

The founding team's journey is rooted in their previous venture, Exbit Technology, a fabless semiconductor startup that was acquired by Vitesse Semiconductor Corp in 2001. This background provided them with deep insights into the limitations of standard cell-based design compared to full custom Integrated Circuit (IC) design, which became the core problem NanGate aimed to solve. The company's business model revolved around providing a comprehensive suite of solutions to semiconductor companies. This included EDA software tools, off-the-shelf physical library IP, and design services. Its revenue was generated through the licensing of its software platforms and fees for its optimization and validation services.

NanGate's flagship offering was its Library Creation Platform, which automated the process of creating, optimizing, characterizing, and validating standard cell libraries. This platform enabled IC designers to enhance performance, manage power consumption, and reduce the physical area of a chip, complementing existing design workflows. The technology was proven across a wide array of CMOS processes, from older 250-nm nodes down to advanced 14-nm nodes available from multiple foundries. This capability was crucial for clients in high-performance data, telecommunications, and other sectors requiring application-specific integrated circuits (ASICs) and systems-on-a-chip (SoCs).

Throughout its history, NanGate achieved several key milestones. It secured a $10 million venture capital investment in 2006 and established a presence in Silicon Valley the same year. The company underwent a management buy-out in 2012, after which it was owned and controlled by its management team, with NanGate, Inc. in Sunnyvale, CA becoming the new headquarters. In March 2018, NanGate was acquired by Silvaco, Inc., another major player in the EDA and IP space. The acquisition was intended to extend Silvaco's portfolio and strengthen its offerings for creating high-performance standard cell libraries. However, the acquisition later resulted in a legal dispute over the earn-out agreement, with NanGate's former shareholders winning a significant judgment against Silvaco in 2024 and 2025.
