Raybox-zero chip: Open-source silicon ray caster 3D game; Tiny FPGA/Verilog "GPU" ASIC | sky130 VLSI

Short presentation: my simple ASIC concept design of a 3D-like "ray caster" video game hardware accelerator chip, FPGA-tested, then synthesised/submitted to TT04 (Tiny Tapeout 04) for VLSI/ASIC manufacture. Created with OpenLane and the sky130 process (Google/Skywater 130nm Open PDK). Designing and getting a real silicon chip made is now available with such a low barrier to entry. After learning the ropes and dabbling with FPGAs, Verilog, and other HDL/RTL concepts, I created this retro-inspired hardware implementation of a simple 3D ray caster that follows the principles used by Wolfenstein 3D, and sent it off to be manufactured on a microchip along with 142 other community designs. 00:00 - Intro 00:55 - Background 01:56 - What is Raybox Zero? 03:05 - Ray caster features 05:21 - Demo video & interaction 06:09 - Working with VGA 07:49 - How it works: Maths 08:47 - How it works: Tracing FSM 10:34 - SPI interfaces 11:36 - Development 12:56 - Code & documentation 13:46 - Questions & answers 16:09 - Concluding thoughts === Amazon affiliate links for products mentioned === /// VGA to HDMI converters: -- VENTION VGA to HDMI Adapter: https://amzn.to/3vjv9Hk -- Duttek VGA to HDMI Connector Cable: https://amzn.to/4ahE1fx -- Mini 1080P VGA to HDMI Adapter (white): https://amzn.to/49V424u /// Other FPGA/VGA and related hardware: -- PMOD-VGA (VGA DAC/buffer): https://amzn.to/3TKyUPm -- iCESugar FPGA Dev Board inc.
