CAMBRIDGE, UK – 14th May 2026 – lowRISC® C.I.C., the open-source silicon engineering organization hosting the OpenTitan® project, is thrilled to announce that Cadence Design Systems, Inc., a global leader in electronic systems design, has joined the OpenTitan coalition as an official Tools Partner.
OpenTitan is the world’s first open-source silicon Root of Trust (RoT) project, bringing together industry leaders to build high-quality, transparent, and trustworthy silicon security. By joining the coalition as a Tools Partner, Cadence continues to provide the OpenTitan engineering ecosystem with access to industry-leading Electronic Design Automation (EDA) technologies, accelerating the development, verification, and ultimate tape-out of OpenTitan designs.
Developing a secure silicon Root of Trust requires rigorous verification, advanced cryptographic testing, and robust physical implementation. The integration of Cadence’s state-of-the-art EDA solutions into the OpenTitan workflow provides the open-source engineering team with the enterprise-grade tools necessary to meet the highest commercial silicon standards.
Empowering Open-Source Silicon with Enterprise EDA As a Tools Partner, Cadence’s contribution will significantly impact the OpenTitan development lifecycle by:
- Supercharging Verification: Enabling the use of advanced logic simulation and formal verification tools to ensure the OpenTitan RTL is functionally correct and highly secure against hardware-level vulnerabilities.
- Streamlining Implementation: Providing cutting-edge synthesis and physical design solutions to optimize OpenTitan for power, performance, and area (PPA).
- Fostering Ecosystem Growth: Demonstrating how proprietary, enterprise-grade tooling can successfully interface with and elevate open-source hardware development methodologies.
