From Open Source Chips to AI Hardware: Highlights from the ECOS Team at the JLC Spark Conference

On September 19, the Shenzhen Convention and Exhibition Center in Futian was packed with visitors for the 4th JLC Open Source Hardware Spark Conference and Global AI Hardware Innovation Ecosystem Summit, hosted by JLC Group. The event attracted more than 2,200 engineers, makers, enthusiasts, industry experts, university faculty members, and students from countries and regions around the world. More than 50 industry partners also exhibited at the conference, showcasing the latest advances at the intersection of open-source hardware and artificial intelligence. The event created a platform for collaboration across the industry and opened a new chapter for the AI hardware innovation ecosystem.

As announced in our earlier article, "The ECOS Team Is Heading to the Spark Conference: Visit Our Booth and Explore Fully Open Source Chips", the ECOS Open Silicon Team (hereinafter the ECOS Team) joined the conference as a partner of the JLC Maker Fair. We brought our in-house open-source chips, development boards, robots, handheld game consoles, and chip design platforms to the event, presenting a range of achievements from across the open-source chip ecosystem. Visitors came throughout the day, from experienced embedded developers to students encountering hardware development for the first time. All showed strong interest in our vision of enabling everyone to design open-source chips.

First Round Open Source 55nm Tapeout Results: Multiple Chips Successfully Brought Up!

The ECOS Team and community users conducted comprehensive testing of the chips from the first open-source 55nm shuttle run, and several chips were successfully brought up. This marks the ECOS Team's transition from a solution that primarily served its own chip designs to an open platform that supports different types of users in developing small-batch chips, based on open-source EDA, open-source IP, and an open-source PDK.

ECOS Team Won the EDAthon 2025 Competition Champion and Thrid Place!

The EDAthon 2025 programming competition, organized by the IEEE Council on Electronic Design Automation (CEDA), Cadence, UniVista, and others, was held at the Hong Kong University of Science and Technology. ECOS Team and a total of 21 teams from universities including Peking University, The Chinese University of Hong Kong, and The Hong Kong University of Science and Technology took part in the competition. After six hours of intense competition, the team of Chaoyu Xing and Xurong Shen from ECOS Team, under the guidance of Teacher Xie Biwei, stood out among many competitors and won the championship of EDAthon 2025! At the same time, the team of Qingling Zhang and Qinhan Zhang from ECOS Team also won the third place in the competition!
