I want to change my VLSI class in the spring (April-June) to utilise your tiny chip infrastructure. If I could say every student in my class got something made, that would be awesome.

I teach digital design in UAE and would be keen to get in contact and learn about the next submission date where my students could submit their test structures for tapeout.

I am a CS and EE teacher and in my final year as a PhD student at the University of South-Eastern Norway (USN). Since we teach courses on both digital and analog electronics, I thought it would be a great opportunity for students to materialise their work.

Built a CRC logic for the http://tinytapeout.com of @matthewvenn with my son. Looking forward if the tapeout happens 🥰 Yet either way, the workflow is astonishing. CI/CD for chip design 🤯

Thank you for doing it - I always wanted to join these OpenMPW shuttles, but never felt ready for it. TinyTapeout provided a way for me to get in, while only spending 1 evening of effort on my end. That’s amazing!

Just made a 4-bit barrel shifter by using this http://tinytapeout.com toolkit. It’s quick and fun to use. The GDS even generated within minutes. Everyone should try this.
