Real Intent Joins OpenTitan as Tools Partner to Strengthen Open-Source Silicon Sign-Off and Verification

CAMBRIDGE, UK – May 18, 2026 – lowRISC® C.I.C., the open-source silicon engineering organization hosting the OpenTitan® project, is excited to announce that Real Intent, a leading provider of advanced early RTL static sign-off EDA software, has joined the OpenTitan coalition as an official Tools Partner.

OpenTitan is the world’s first transparent, high-quality, open-source silicon Root of Trust (RoT). Building a secure silicon foundation requires impeccable code quality and the elimination of hardware bugs long before the design reaches physical implementation. Real Intent provides the OpenTitan engineering community with access to its industry-leading static sign-off solutions, ensuring the highest standards of structural integrity and security.

Elevating Code Quality with Advanced RTL Sign-Off

Real Intent’s specialized tool suite—including static sign-off solutions for Hardware Security, Linting, Clock Domain Crossing (CDC), and Reset Domain Crossing (RDC)—play a crucial role in the OpenTitan development lifecycle. The integration of Real Intent’s software empowers the open-source engineering team to:

• Fortify Silicon Security: In secure hardware design, clean RTL is the first line of defense. Advanced hardware security static sign-off with Sentry helps eliminate corner-case vulnerabilities that could be exploited by physical attacks.
• Accelerate Early Verification: By utilizing Real Intent’s advanced linting tool Ascent Lint, developers can identify and resolve complex structural issues and coding violations natively at the RTL stage, dramatically reducing debugging time later in the design cycle.
• Ensure Robust Domain Crossings: Secure SoCs like OpenTitan rely on complex clock and reset architectures. Real Intent’s industry-standard Meridian CDC and Meridian RDC verification tools will help prevent metastability and data loss, ensuring the chip operates flawlessly under all conditions.
