Abstract:
This live stream (Open Source Silicon Stream #9) provides updates on the open-source silicon landscape following the eFabless shutdown, discussing potential alternative MPW access routes including IHP's upcoming paid service, a potential Cadence Sky130 run, and interactions with CMC/GlobalFoundries. It highlights a new collaboration with TechXplains for chip imaging services, showcasing results and an interactive web viewer for Tiny Tapeout 6. The core of the stream focuses on the successful live bring-up and testing of the first IHP 130nm test silicon, demonstrating several working user designs (VGA games/demos, audio output) submitted through Tiny Tapeout. The stream also previews the diverse range of designs included on the subsequent, densely packed IHP shuttle (0.25a) and promotes community resources like the FOSSi Chat server and an open letter advocating for accessible open-source chip manufacturing.
0:00:05: Welcome to Open Source Silicon Stream #9; host Matt Venn returns after attending Hackaday Berlin and DATE conference.
0:01:55: Positive feedback from DATE conference, highlighting community enthusiasm and support for Tiny Tapeout.
0:02:16: News Update: Status of eFabless shutdown and MPW alternatives.
0:02:42: Still awaiting confirmation from CMC regarding GlobalFoundries PDK access.
0:03:12: Provisional news: Cadence may run a Sky130 MPW shuttle around May (follow David Jun on LinkedIn for updates).
0:03:38: IHP Update: Initial test chips (funded by German BMBF) were available for loan within the EU only.
0:04:06: IHP is launching a paid silicon service; Tiny Tapeout plans to run its first paid shuttle with IHP in late 2024 or early 2025, allowing chips to be sent anywhere.
0:04:29: A questionnaire will be sent to the Tiny Tapeout mailing list soon regarding future plans and preferences.
0:05:10: Collaboration announced with TechXplains, a French reverse engineering company, for chip decapping and imaging.
0:05:46: TechXplains successfully imaged Tiny Tapeout 6, removing Metal 5 for better silicon art visibility. SEM images shared.
0:06:46: Uri Shaked integrated these images into an interactive online viewer, allowing comparison between microscope images and GDS layout. High-res images also available via Silicon Prancer.
0:09:32: Brief discussion on geopolitics and the complexities of onshoring semiconductor supply chains, referencing an EDACafe interview.
0:11:37: Mention of a video testing Ricardo Nunes's 12-bit SAR ADC from Tiny Tapeout 7, confirming basic functionality.
0:12:58: Recap of Hackaday Berlin lightning talk featuring "semiconductor music" (transistor rap); a re-recorded version is available.
0:13:44: Encouragement to sign the open letter advocating for accessible open-source chip manufacturing.
0:15:09: Main Topic: Live testing of the first IHP test chips.
0:15:34: The first batch of IHP 130nm test chips have arrived, wire-bonded by IHP. Some have lids off for viewing.
0:16:59: Sylvan conducted a live silicon bring-up stream, noted as a brave and unique effort in the open-source hardware community.
0:18:10: Details of the first test chip: Contained 24 designs merged into a single Verilog file, hardened together without the usual Tiny Tapeout multiplexer or power gating.
0:19:55: Live Demonstration: Testing designs on the first IHP silicon using the Tiny Tapeout demo board.
0:20:31: Leo's "Sprite Pony" VGA design is tested and confirmed working.
0:23:39: VGA Clock design tested and working; state is retained between selections due to lack of power gating.
0:24:37: "Flappy VGA" design tested; does not work (crashes immediately).
0:25:35: Rohan's "VGA Dino" game tested and is playable; high score achieved during stream: 129.
0:28:12: Anton's "Raybox Zero" VGA raytracing demo tested and working.
0:30:04: Super Mario audio demo tested; sound output confirmed working via a piezo speaker connected to bidirectional pins. Music plays correctly.
0:38:18: Mention of another design on the chip: AY38913 chip tune synthesizer.
0:39:14: Key Takeaway: The first IHP test chips are working, validating the PDK and toolchain integration.
0:39:28: Update on the second IHP test chip (shuttle 0.2, including the standard Tiny Tapeout mux): Manufacturing was delayed but has now been submitted.
0:40:07: Discussion shifts to the third IHP chip (shuttle 0.25a), funded by Swiss Chips Initiative and BMBF.
0:40:46: Shuttle 0.25a is densely packed with designs from Tiny Tapeout 8, 9, 10, and compressed workshop submissions. Browsing through submitted designs.
0:42:23: Notable 0.25a designs include: Sam's Digital Desk Clock, Thomas's Linear Time Code generator.
