Efabless Shutdown and the Future of Open Source Silicon

• 0:00:11 Introduction: The stream focuses on the shutdown of Efabless, a key player in the open-source silicon movement.

• 0:00:33 No Speculation: The speaker explicitly states they won't speculate on the causes of the shutdown, future plans for Tiny Tapeout, or potential future developments in the field.

• 0:00:47 Tiny Tapeout Updates: Information about Tiny Tapeout will be posted on LinkedIn, and customers will receive an email.

• 0:01:32 Matt Venn's First Chip: Shared a picture of his first ever chip. "I still kind of can't believe it's true".

• 0:01:53 Arduino Parallel: The speaker draws a parallel between the democratization of microcontrollers (like Arduino) and the increasing accessibility of semiconductor design.

• 0:02:24 Meeting Tim Edwards: The speaker's journey into open-source silicon began after meeting Tim Edwards (formerly of Efabless) and seeing an open-source chip using the P rv32 core.

• 0:03:05 Skywater 130nm PDK Announcement: A pivotal moment was the 2020 announcement of the Skywater 130nm PDK, with Google funding free tape-outs and Efabless running the shuttles.

• 0:03:34 OpenLane: The introduction of OpenLane, bundling OpenROAD and other tools, was crucial.

• 0:03:43 Personal Involvement: The speaker actively participated in every shuttle, taped out at least 10 chips, and started the "Zero to ASIC" course.

• 0:04:45 Maximizing Space: Early on, the speaker realized the ample space on the chips (10 sq mm) and focused on maximizing its use and involving more people.

• 0:05:14 Community Growth & Slack: Efabless played a central role in the rapidly growing community, including hosting the open-source silicon Slack channel.

• 0:05:23 FOSSI Matrix Chat: The community is transitioning to the FOSSI Matrix chat server (led by Leo Moser) as the Efabless Slack channel loses its history.

• 0:06:03 ChipIgnite: Efabless launched ChipIgnite, the commercial version of the lottery system, which Tiny Tapeout later used.

• 0:06:19 Early Challenges: The first chips had significant problems with the pad frame and GPIO configuration, making them difficult to use.

• 0:07:33 Full Wafer: Shows mpw3 full wafer with 40 different open source designs.

• 0:08:28 Tiny Tapeout Launch: The first experimental Tiny Tapeout occurred in September 2022.

• 0:09:08 Efabless's Central Role: Efabless was integral to the growing community, and the speaker collaborated with them on various projects, including training and webinars.

• 0:09:39 Impact of Shutdown: The speaker expresses disbelief and sadness at Efabless's closure.

• 0:10:53 Tiny Tapeout relied on Efabless: $10,000 shuttle was 4-5 times cheaper than industry average.

• 0:13:23 Visiting Efabless: The speaker is grateful for having visited Efabless last year, meeting Jeff, Muhammad, and Pat.

• 0:14:30 Gratitude and Best Wishes: The speaker expresses gratitude to Efabless and wishes the team well, encouraging others to connect with them on LinkedIn for job opportunities.

• 0:15:29 Optimism and Future Plans: Despite the loss, the speaker remains optimistic about the future of open-source silicon. Tiny Tapeout plans to continue its mission.

• 0:16:06 IHP Shuttle: The next public Tiny Tapeout shuttle is scheduled for later this year on IHP.

• 0:16:18 Future Collaboration: Tiny Tapeout is already in communication with multiple foundries.

• 0:16:24 Stay Informed: The speaker urges the audience to follow Tiny Tapeout on LinkedIn and join the FOSSI chat Matrix server for updates.

• 0:16:38 Exciting Future: The speaker believes this year will be the most exciting yet for open-source silicon, with growing enthusiasm and understanding of its importance.

• 0:17:07 Call to action "Keep Calm and make ASICs"
