Working through its Open Source Programs Office (OSPO), Google is actively engaged in helping seed the open silicon space. Specifically by providing funding, strategic, and legal support to key open hardware efforts including lowRISC and CHIPS alliance.
lowRISClowRISC is a leader in open silicon community outreach, technical documentation, and advancing the goal of a truly open source system on a chip. We have long supported lowRISC’s mission of transparently implemented silicon and robust engagement of the open source silicon community, providing funding, advice, and recognizing their open source community leadership by selecting them as a Google Summer of Code mentoring organization.
Similar to the benefits of open source software, we believe our users will derive great outcomes from open source silicon. Besides enabling and encouraging innovation, chip designs derived from a common, open baseline will provide the benefit of implementation choice while still guaranteeing software compatibility and a set of common interfaces. With regards to security, the transparency of an open source approach is critical to both bugfinding and establishing implementation trustworthiness.
"Google has encouraged and supported lowRISC since the very start. They clearly share our optimism for what open source hardware can offer and our community-driven vision of the future. We are excited by the expanding open source RISC-V ecosystem and look forward to lowRISC community IP being deployed in the real world,” said Alex Bradbury, Co-founder and Director. “We believe lowRISC can act as an important catalyst for open source silicon, providing a shared engineering resource to ensure quality, provide support and help to maintain IP from a range of partners.”

Furthermore, Google is excited to announce that it is joining the board of lowRISC, with the appointment of Dominic Rizzo and Ronald Minnich as corporate directors.
CHIPS AllianceAlong with our increased funding, support and collaboration with lowRISC, we are also happy to announce our status as a founding member of the Linux Foundation’s CHIPS Alliance project. CHIPS Alliance features an industry-driven, collaborative model to release high-quality silicon IP and supporting technical collateral. Most recently, in collaboration with CHIPS Alliance, we released a Universal Verification Methodology (UVM) instruction stream generator to aid in the verification of RISC-V cores. We believe such open sourcing of verification tools will prove critical to the long-term success of the open source silicon community.
Google has been an early, strong supporter of the open silicon community. We believe deeply in a future where transparent, trustworthy open source chip designs are commonplace. To get there, we are committed to establishing a collaborative, community-focused, open source basis for free and open silicon design.
