wafer.space bare dies and CoB have arrived! 🎉
These are from my open-source FABulous FPGA, which was part of the first shuttle run.
It's a small FPGA with 480x LC, 6x MAC, 12x register files and 6x SRAM. The source files are available in the repository: https://github.com/mole99/gf180mcu-fabulous-fpga -
Greyhound is alive! 🐶
Last week, I posted about soldering my custom chips onto breakout boards. Now, I can finally say that Greyhound is working 🎉
If the video below doesn't work, you can also view it on Peertube: https://makertube.net/w/3rQ8a7WxTYcr1BQY9nCUatI'm incredibly happy that Greyhound is no longer just theoretical, but that it can run examples on its FPGA in the real world 🤩

And this is an artistic PCB with the #TinyTapeout logo. However, what you may not realize at first glance - the pattern represents standard cells from a real chip. Coincidentally, my design from TT06 was picked for the background! You can find it here: https://github.com/mole99/tt06-tiny-shader
The files for generating the PCB from a GDS can be found here: https://github.com/htfab/tt-coaster
Thanks, Tamas!

Tiny Shader running on the GateMateA1-EVB with an open source toolchain 🎉
Originally this design was created for Tiny Tapeout, more information can be found here: https://github.com/mole99/tt06-tiny-shader
And if you want to see the TT06 chip in action, take a look at this thread: https://fosstodon.org/@mole99/113730908871370284

They're finally here 🎉️ My very own chips from the Google-sponsored MPW-8 shuttle!
Open source chip design is real and here to stay.The entire delivery includes bare dies, QFN packaged parts, daughter card assemblies, and a development board.
Many thanks to Efabless for managing the chip fabrication and delivery!What's inside it? A simple RISC-V SoC with various peripherals, you can find my submission repository here: https://github.com/mole99/leosoc-sky130

Hi everyone! This is my very first toot :)
I would like to take the opportunity to present one of my latest projects:
A generic waveform generator implemented as an ASIC using the open source SKY130 PDK. With a bit of luck, this will be fabricated in the MPW-7 Shuttle through the Open MPW Program.
Development repository: https://codeberg.org/mole99/waveform-generator
ASIC implementation: https://codeberg.org/mole99/caravel_wfg
Project submission: https://platform.efabless.com/projects/1202 -
The next step is testing the chips. However, I need more time to setup the development environment. Stay tuned!
Thanks to @tnt for his soldering advice and for sharing his Tiny Tapeout IHP Breakout board, which I forked for the Greyhound Breakout PCB.
You can watch his bringup of the IHP 25A Tiny Tapeout chip here: https://www.youtube.com/watch?v=l0BNbLQ6u8g

And another chip submitted for tapeout - HeiChips 🎉
This one has been in the works for some time, but since the shuttle was canceled last fall, it was postponed to a later one.
It's an open-source chip featuring user projects created by participants of the HeiChips Summer School 2025 (https://heichips.github.io/). How cool is that?
The chip uses 9mm² of silicon on SG13CMOS and has been submitted to IHP's Low-Cost MPW shuttle (https://dk.ihp-microelectronics.com/OpenSourceRequest.php).More below ⬇️

A Tiny FABulous FPGA on Tiny Tapeout? It's more likely than you think!
Yesterday the TTIHP26a shuttle (https://app.tinytapeout.com/shuttles/ttihp26a) from #TinyTapeout has closed. In it, hundreds of incredible projects.
You can view the full shuttle and its designs here: https://app.tinytapeout.com/projects/3744I had the opportunity to submit an FPGA, which I created using my FABulous LibreLane plugin. For this fabric, I developed a "tiny" tile library that better fits the constraints of Tiny Tapeout.

I'm super happy that my PR for pad ring generation has been finally merged into LibreLane!
This allows you to implement a full chip, including the pad ring - who would have thought?It is currently part of the LibreLane dev branch. Check out LibreLane here: https://github.com/librelane/librelane

Look what arrived on my doorstep today! 👏
A limited 1st edition collectible from the silicon vault.

I've got myself a new toy 🙌
This is the GateMateA1-EVB from Olimex, an FPGA dev board containing the GateMate CCGM1A1 with 20480 CPEs.
Now that initial nextpnr support for the chip has been merged, it is possible to program it with a fully open source toolchain 🎉
Synthesis with Yosys, place and route with nextpnr, bitstream packing with gmpack and finally upload to the board with openFPGALoader!That meant I just had to get one, and two days later it arrived!
