We submitted Tiny Tapeout 2 back in December, and last week I received the chips from Efabless.

Most first chip designs fail, but you never hear about it because the big companies keep it a secret. So we thought - why not do the world’s first public silicon bring up?

Thankfully the chips worked, and you can watch the whole stream here.

We’ve since found 1 errata, but luckily not a show stopper.

I had a lot of fun working through the datasheet and picking designs to test. Here’s a video of me showing off the following designs:

And here’s links to those designs:

• random number generator https://tinytapeout.com/runs/tt02/086
• worm in a maze https://tinytapeout.com/runs/tt02/084
• M0 subleq https://tinytapeout.com/runs/tt02/039
• Pi 1000 places https://tinytapeout.com/runs/tt02/036
• dice roll https://tinytapeout.com/runs/tt02/061
• breathing led https://tinytapeout.com/runs/tt02/068/
• lcd namebadge https://tinytapeout.com/runs/tt02/056

We’re looking forward to getting the boards manufactured at Aisler and getting them sent out to the 165 people who submitted designs!
