Rickroll meme immortalized in custom ASIC that includes 164 hardcoded programs
The project is a product of Matthew Venn's Zero to ASIC Course, which offers prospective chip engineers the chance to "learn to design your own ASIC and get it fabricated." Since 2020, Zero to ASIC has accepted several designs that are incorporated into a single chip called a multi-project wafer (MPW), a cost-saving measure as making one chip for one design would be prohibitively expensive.
Zero to ASIC has two series of chips: MPW and Tiny Tapeout. The MPW series usually includes just a handful of designs, such as the four on MPW8 submitted in January 2023. By contrast, the original Tiny Tapeout chip included 152 designs, and Tiny Tapeout 2 (which arrived last October) had 165, though could bumped up to 250.
Of the 165 designs, one in particular may strike a chord: Design 145, or the Secret File, made by engineer and YouTuber Bitluni. His Secret File design for the Tiny Tapeout ASIC is designed to play a small part of Rick Astley's music video for Never Gonna Give You Up, also known as the Rickroll meme.
Bitluni was a late inclusion on the Tiny Tapeout 2 project, having been invited just three days before the submission deadline. He initially just made a persistence-of-vision controller, which was revised twice for a total of three designs.
