Kindof crazy what Matt managed to do in little time, in *analog* ASIC land, with the help of the bots... see how he tamed the machine and got it to make something that works (in theory!? we'll see!).
I designed an analog mixed-signal radio chip with an AI agent: about 700 prompts in a week, and it's now submitted for tapeout.
Here's how it went at each step of the design, the times it was confidently wrong, and how I caught them.

#ASIC #opensource
The @hackaday #Supercon 10th edition is coming up fast and, though the full schedule's not up yet, the @tinytapeout workshop is ON and will be on Friday 6th: Come! Make a chip! It's going to be fun :)
Add that TinyTapeout workshop or other extras at eventbrite.com/e/19967592988…
New form-factor for GF180 TT ASICs panelized for wirebonding. Can be used as a raw IC or have designs loaded and/or clocked by the CH32 MCU, while giving external circuitry access to all I/O along with a USB TUI, using github.com/psychogenic/TT-DI… (built on the amazing ch32fun lib).
First day of @tinytapeout workshop at the IEEE Latin America & the Caribbean Semiconductor Summit , in Panama. Congrats all who sculpted silicon and got to tape out! Big thanks to TAs--Andrea, Denis, Josue and Oriel--and to Fernando and @IEEEPanama for making it happen!
Agree. I've clashed with these people, who seem to know nothing other than how to convince the state to use its guns to force their ideas (and grow its own power), eg plans to artificially raise cost of electricity. Here,where it's all HYDRO power and they're forcing EVs on us.
I'd never heard of Transport Triggered Architecture (TTA) CPUs before--kinda cool--and @BreakingTaps managed to design and tapeout an actual (mostly?) working chip. A great intro to the topic and the architecture

yeah, this looks interesting

Connect with its shielded cable and ADC module 😆
Do you want get it in $99 ?

Trust In The Age Of AI: Verifying Authentic Creations And Why You Should Care
Getting pretty hard to tell what's what, and I'd like to make sure what I'm consuming is real and supporting the creators I love rather than the flood of BS coming our way.

Anyone can steal your face. All this power is cool, but if you put anything online... oof. Well, there's a solution to this, something that can let you know if that really is from your favorite creator

Have been meaning to play with Mini MOSbius, an "analog FPGA", and Matt walks through the cool system he built around it.
Forget simulation - watch me build and speed up a circuit on silicon, live!
I'm using Mini MOSbius - it's like an FPGA but for analog.

This sensor does neat quantum magic to count full turns *without power*. The full video is out, including electronics and a look at the physics behind the cool youtube.com/watch?v=zNJ-RbrO…

oh, this'll be interesting--EM solvers right from FreeCAD

New workbench for RF and microwave engineering! This is an audacious WIP that is typically seen in the ecosystem. Current solver that works is openEMS but several others are slated. Props to Mike Volokhov

Acoustic side-channel attack--letters from keyboard sounds--on an *MCU* @ 7ms, ~100 micro Joules per inference. The model was built just by feeding my data to a web service that spits out C for the microcontroller. Full build, demo and deets: youtube.com/watch?v=dbXCghmn…
Chipalooza #3 is on: design sweet open source analog ASIC circuits for GF180, win glory, fame, and prizes (well, maybe get paid) and have fun doing so. Open to proposals until the end of the month

Did not know Justin Feinstein: this was a fun read, very timely. Ate it in a single gulp.

Thunderstorms in Chicago had me stuck with an 11 hour layover at SFO... randomly popped over at @noisebridge where I got a warm welcome, a tour, a spot with a wifi and a number of cool convos. Now that's my kind of anarchy, what a cool place! Check it out if you're in Frisco.
