AI Generated Open-Source Silicon
Design Challenge

Ignite your creativity and be part of our Second AI-Driven Open-Source Silicon Design Challenge

Witness firsthand how Generative AI is transforming the chip design landscape, empowering you to easily create cutting-edge designs with unlimited potential in less than two months!


Use generative AI (e.g. chatGPT, Bard or similar) to generate a complete Verilog model for a digital design. The design must be implemented using chipIgnite that includes an SoC template (Caravel) providing rapid chip-level integration and an open-source RTL-to-GDS digital design flow (OpenLane).

A successful project must provide all prompts used to generate a complete RTL model for the design. In addition, verification testbenches that demonstrate the design meets the intended functionality must be provided and maybe created conventionally.

See the following video example.

Also checkout the winners from the first contest.


Be among one of the first to design and tapeout an AI generated open-source silicon design. Participants will be eligible to win free fabrication for their design and receive public recognition and promotion of their design by Efabless. We are targeting to select at least three winners and designs to be fabricated based on the quality of the submissions. We are also working with industry partners to support fabricating additional projects.

In addition, each submission that meets the requirements will received a development board with a fabricated chip from one of the winning projects.

How to Enter

  1. Register on the Efabless platform if you have not already done so.
  2. Join the challenge channel #generative-ai-silicon-challenge on Slack space for updates and additional help and resources.
  3. Submit your entry by including all content on a public GitHub repo.
  4. Create a public project for the chipIgnite CI 2309 shuttle using the GitHub repo from the previous step. Please include AI-design-contest in the label field when you create your project.
  5. Submit success precheck and tapeout jobs for your design.
  6. Complete the remainder of the billing and shipping information as well as terms and export agreements. You will not be charged or invoiced for your submission. Complete the final submission for the project on the platform.
  7. Send an email to with a link to your project.

Limit one entry per person, per email address. Your entry must be original.

Note: If you have not received permission to use copyrighted material, you may not include the material in your entry.

Judging Criteria:

All designs will be judged by a panel of experts who share a lifelong commitment to electronics and believe in the power of AI and machine learning to drive innovation. Stay tuned for more details!

  • Project Documentation
  • Prompt Documentation
  • Code
  • Verification Coverage
  • Technical Merit
  • Project Description and Community Interest Poll

All requirements must be met to be eligible to win

  1. All submission content, documentation, prompt must be in English
  2. A short description of the project must be included with your design. It will be used for introducing your idea in the community poll.
  3. All designs must be implemented and fit in the Caravel User Project area.
  4. The Verilog for the design must be coded by AI.
  5. Verification may be done outside of the AI environment but verification testbenches must be provided as a reproducible element of this process.
  6. All prompts or auto GPT session logs used in the design must be provided as part of the deliverables for the design.
  7. The design needs to be open source with all materials required to reproduce made public.
  8. To facilitate reproducibility by the community, we recommend the design be implemented using the OpenLane chipIgnite flow including all configuration and run results. However, we will accept any open-source implementation flow provided it is documented and reproducible.
  9. Must have testbenches for RTL verification as well as constraints for STA and SDF simulations.
  10. Must be implementable in SKY130 with available standard cells and DFFRAM and not require open RAM or other discrete memories for implementation.
  11. The design must pass precheck and tapeout submissions on the Efabless platform.
  12. Winners must provide a video and screenshots demonstrating the creation of the project in a how-to or step-by-step format. The images and link to the video must be included in the documentation for their project in the GitHub repo. These materials may be used by Efabless for promotional purposes.
