Google is moving forward with providing free open-source silicon manufacturing from GlobalFoundries



Google announced silicon manufacturing funding for participating open source projects using the Process Design Kit with GlobalFoundries.

As part of Google’s efforts to give open source projects easier access to silicon design and chip manufacturing, they had opened up resources and covered the costs of open source projects to manufacture their first chips on a 130nm SkyWater process followed by an upgrade to 90nm SkyWater. treat. In August, it was announced that Google and GlobalFoundries had created an open-source process design kit (PDK) to target GloFo’s 180nm “180MCU” technology platform.

In the initial announcement, it was implied that Google would continue to offer its “no-cost silicon fulfillment program” to cover early batches of chip manufacturing for those who complete a successful open-source chip design. With the SkyWater program, Google covered the costs of six shuttle rides that resulted in 350 unique silicon designs and about 240 of them were successfully manufactured.


Google has now officially announced its funding for manufacturing open source silicon using this 180nm GlobalFoundries PDK. There will be a series of free shuttles using the GF180MCU over the next few months. As with previous runs, silicon designs must be fully open-source, must be reproducible from source designs, must be submitted on time, and must pass pre-manufacturing checks. Although 180nm is not interesting for high-end PC components, 180nm still has many real applications and is used in a wide variety of fields such as IoT, automotive and other more electronic components basics.

180nm manufacturing for processors was used at the time in some Intel Celeron processors for Socket 478 (pictured) as well as AMD Athlon Thunderbird and Duron processors, among others. GlobalFoundries’ 180nm fabrication is still useful for other ASICs, especially for early-stage open-source projects whose costs are covered by Google.

The first test shuttle is running until Dec. 5 for submissions. Those interested in learning more can view this Google blog post from their Open-Source blog with this shuttle sponsorship announced on October 31 but not appearing on their RSS feed until this weekend.
