Tenstorrent unveils the Open Chiplet Atlas Ecosystem, an open source architecture enabling plug-and-play chiplets.
Tenstorrent has launched the Open Chiplet Atlas (OCA) Ecosystem, including the open standard OCA Architecture, aiming to create a truly open chiplet market.
The ecosystem aims to democratise chip design, reduce development costs, and accelerate innovation by enabling heterogeneous chiplets for plug-and-play interoperability. Over 50 partners have joined the initiative, spanning leading semiconductor companies, global conglomerates, and academic institutions.
Traditional monolithic system-on-chip (SoC) designs are increasingly complex, expensive, and time-consuming. The OCA Ecosystem addresses these challenges by standardising chiplet interoperability across physical, transport, protocol, system, and software layers.
The OCA Architecture is modular, open source, and ISA/IP neutral, free from vendor lock-in. It provides greater design flexibility and faster time-to-market across AI accelerators, automotive solutions, and data centre products. Draft v0.7 of the OCA Architecture Specification is publicly available at Open Chiplet Atlas.
“The future of silicon is heterogeneous and composable,” said Wei-han Lien, Chief Architect at Tenstorrent. “The OCA Ecosystem establishes the foundation of trust and interoperability needed to unlock the full potential of multi-vendor chiplet-based SoC products. This is not just a new standard—it’s the beginning of a collaborative community that will drive the next generation of system innovation. The OCA Ecosystem starts a new silicon design paradigm.”
The OCA Ecosystem is built on three pillars: Architecture, defining interoperability across five layers; Harness, an open source design framework enabling automatic interoperability; and Compliance, ensuring end-to-end verification with a “Golden Chiplet” and community Plugfests.
The open source approach empowers designers worldwide to adopt, contribute, and collaborate, accelerating innovation and driving a new community-driven chip design paradigm.
