TT02 ASIC/board: Open source silicon chips on Tiny Tapeout! sky130 VLSI design getting started cheap

Cheap custom chip manufacturing is here! Open source made Tiny Tapeout possible for beginners and experts alike. I review the TT02 ASIC, board, and look forward to VLSI's future of Open PDKs like Skywater 130. Interested in chip design, professionally or as a hobbyist? Total beginner, worked with FPGAs, or thinking about HDLs like Verilog? Curious how to get your own design hardened and characterised in silicon, but thought it was too difficult or costly? You might want to check this out. The Tiny Tapeout shuttle was recently manufactured, along with a demo/test board that features an Efabless “Caravel“ chip with 161 open source standard cell designs from members of the open source silicon community. 00:00 - Intro 00:48 - Board overview 01:53 - Power-up and use 04:22 - Clock control 05:55 - Explore designs 06:48 - External DIPs 07:12 - Breathing LED 07:49 - Loading Animation 08:51 - Siren 09:36 - Many more designs 10:17 - What next? 10:59 - TT03 to TT06 11:32 - Closing === Links and resources mentioned: === * Zero to ASIC Course: * Tiny Tapeout: * Tiny Tapeout TT02: * TT02 live bring-up: * Psychogenic Technologies: * TT01/02/03 Demo Board info: * TT04 Demo Board info: * Clocking & Clock divider: * TinyTapeout 3.5 demo: === Specific TT02 design links: === * #68: Breathing LED: * #28: Loading Animation: * #28 on Wokwi: * #37: Siren: * #36: Pi: * #2: HD74480 Clock: * #25: Transmit UART: * #75: Ring OSC Speed Test:
