In my recent video Getting started with open source ASICs, I provided an overview of the open-source silicon movement, highlighting key resources and tools while showcasing some inspiring projects.

The video starts by looking back at the game-changing moment in 2020 when Google, Tim Ansell, and Efabless announced their free shuttle program, making it possible for anyone to get their open-source chip designs manufactured. This sparked a wave of innovation, with many taking their first steps in ASIC design using open-source tools like OpenLane and the Skywater 130nm PDK.

I then walk through the evolution of my own journey, starting with my first chip design in 2020, a VGA clock that I’ve since taped out multiple times, pushing the boundaries of complexity and collaboration with each iteration.

The video then shifts to the vibrant open-source silicon community. With thousands of members on the Open Source Silicon Slack channel, the community provides a supportive environment for sharing knowledge, collaborating on projects, and pushing the boundaries of what’s possible. This collaborative spirit is a key strength of the movement, breaking down the traditional silos of the semiconductor industry.

Of course, no introduction to open-source ASIC design would be complete without a look at the tools. I provide an overview of the most popular tools, including OpenLane, OpenLane 2, and Silicon Compiler, all of which are freely available and can be used to design chips from start to finish. I also highlight some of the challenges and areas for improvement, such as the need for more robust verification tools, better support for analog and mixed-signal design, and continued development of open-source IP libraries.

To make it easier for newcomers to experience the thrill of designing and manufacturing their own chips, I introduce Tiny Tapeout, a project that allows multiple designers to share the cost of a chip fabrication run. Tiny Tapeout offers a low-cost, low-risk way to get your designs manufactured, making it ideal for students, hobbyists, and professionals alike.

I conclude the presentation by showcasing a diverse range of projects built using open-source tools, from a microcoded USB peripheral and a 5 GHz satellite transceiver to a RISC-V CPU and an AI accelerator. These projects demonstrate the potential of open-source ASIC design and hint at the exciting possibilities that lie ahead.

Whether you’re a seasoned engineer or a curious beginner, I encourage you to check out the video and explore the world of open-source silicon. With the right tools, resources, and a collaborative spirit, the possibilities are limitless.
