Combining semiconductors with music for my @hackaday Berlin lightning talk - check out this exciting Tiny Tapeout update!
Enjoy the videos and music you love, upload original…

Instant device bench envy!
Had some fun testing Ricardo Nunes's 12bit SAR ADC on #TinyTapeout 7 this afternoon.
A SAR ADC is a nice mixed signal example, with the digital section coordinating the binary search of an internal DAC, homing in on the input signal.
Glad I could test it myself and see it working!
Last few days for Tiny Tapeout 10!
The shuttle closes at 21:00 CET / 12:00 PT on Monday 10th of March.
We have some great projects on board already, including 3.3v mixed signal analog, a bandgap reference, the demoscene competition entries and RISCV SoCs.
But we want even more, so put on your ASIC hat and get that last minute design submitted onto Tiny Tapeout 10!
Tiny Tapeout 10 demoscene competition is open! Enter for free and win some great prizes!

HackadayDon't miss my next open source silicon stream!
As well as the latest news and events I'll be looking at some new silicon proven designs and look at reading and writing via SPI.
This is the QSPI clock being output from my TinyQV design on #TinyTapeout 06.
It's a 32MHz clock, which should be within spec of the Tiny Tapeout outputs, which are rated to 33MHz.
As you can see, a couple of the clocks are rather low. This does just about work, but definitely warranted further investigation!
In the video above, it is acting as an 8 bit shift register with feedback, so in theory, we could build another layer now :D
I also did a time multiplexed nand gate on #tinytapeout 4, but then I didn't have the shift registers so I could only fit 128 bits of state compared to the 880 (in 2 tiles) here.
Of course, the tradeoff is time. Me and a friend think we will be able to fit an RV16I on this, but it will run at literal HZ with the ASIC clocked at MHz
What is it you may ask? It is a time multiplexed NAND-gate and a giant shift register. Schematically, it looks like this.
Every clock cycle, it can read a value from the top of the shift reg to either the left or right operand, and write an input or the current NAND output back into the shift register.
This is able to emulate any circuit with <880 bits of state+wires, but it won't be fun to program, nor fast.
Going to stream programming my #tinytapeout submission for a bit over on https://www.twitch.tv/thezoq2.
Let's see if we can make a single NAND gate do something useful

Twitch8/ How do I put data in memory in the first place? #TinyTapeout is an amazing project with amazing tools, and the demo board has a RP2040 onboard with micropython on it. So you can use that to initialize ('flash') data in the PSRAM pmod before starting your design.
urish already made a great tool just for that!

GitHub2/ To me, this is crazy ; when I started on #FPGA and #Silice back in 2018 I never *dreamed* of one day having my own design on silicon. Thanks #tinytapeout, @matthewvenn, and everyone involved who makes this possible!

Quicker, easier and cheaper to make your own chip!Has anyone made a solar-powered electronic touch #MorseCode paddle? It feels like this is something that could be done with a pocket calculator solar cell at this point. Maybe RFI can ruin it?
This might be motivating enough to get me to learn a bit of IC-level design and join a future #TinyTapeout

HackadayCustom shaders are working on my Tiny Tapeout 06 project "Tiny Shader"! 
️
The video shows the VGA output on a monitor, each shader uses up to 10 instructions. There's a short gap during which a new shader is uploaded before the monitor displays it.
If you would like to write your own shaders (and emulate them), take a look at the "sw" folder in the repository: https://github.com/mole99/tt06-tiny-shader
If you send me your shader code, I will try it out on the real hardware 
️
I'm going to start a regular weekly stream about #opensource silicon. Topics will include design, verification, #fpga, openlane, formal, #tinytapeout, #ASIC bringup, chip validation.
If you're interested, please let me know what days / times work for you:
TinyQV on #TinyTapeout 6 update: I have a CoreMark! 4.969 isn't going to be making any headlines, but it will be interesting to compare to other TinyTapeout SoCs.
And I have a #MicroPython port up and running! GPIO and SPI work, as does mpremote (but not Thonny for some reason). Next on the list will be trying to mount a filesystem on an SD card over SPI.
