Origins: DARPA Electronics Resurgence Initiative

OpenROAD began as part of the U.S. DARPA Electronics Resurgence Initiative (ERI), a major research effort launched in 2017 to tackle persistent challenges to Moore’s Law by encouraging radically new approaches to electronics design and automation. ERI invested in foundational research to lower the cost, complexity, and time required for designing advanced semiconductor systems

UC San Diego and Early Research

The original ERI award for OpenROAD was made to the University of California, San Diego, with Andrew B. Kahng as Principal Investigator. Under this support, the team explored whether a fully autonomous RTL-to-GDSII digital design flow could be achieved using open-source tools — a vision that promised to democratize chip design by reducing dependency on costly proprietary software.

OpenROAD was publicly introduced at the inaugural ERI Summit in 2018, where it was showcased to a broad audience of academic, industry, and government stakeholders as a bold research prototype for next-generation electronic design automation.

From Research Prototype to Community Platform

During the DARPA ERI phase, from July 2018- Dec 2023, OpenROAD achieved key milestones:

• A demonstration of a complete autonomous design, No-Human-In-Loop (NHIL) flow that enabled hardware engineers to innovate without the barriers of costs, licenses and EDA tool complexity
• A modular, open-source architecture that is flexible, extensible and supports integration to other tools
• Early adoption in academic research, teaching, and exploratory use by industry
• Traction in chip design education and workforce development for the semiconductor industry

NSF POSE Phase II Award (Award ID 2449356)

To steward OpenROAD’s transition from a research prototype into a sustainable, community-governed open-source ecosystem, the project was selected for funding under the National Science Foundation’s Pathways to Enable Open-Source Ecosystems (POSE) Phase II program.

Under NSF Award 2449356, titled “Growing a Collaborative Ecosystem for Open-Source Chip Design Using OpenROAD”, the OpenROAD Initiative — led by UC San Diego with collaborators at Arizona State University, Brown University, and industry partner Precision Innovations Inc — is building the organizational, technical, and community foundations for a long-lived open-source chip design ecosystem.

This award funds activities to:

• Establish governance and community infrastructure for OpenROAD;
• Support integration of EDA tools and scalable software distribution;
• Promote onboarding and training for developers and users;
• Advance open-source workflows across chip design domains;
• Strengthen education and workforce pathways tied to open-source hardware.
