GoKawiilIndependent engineer publishes solution to Jane Street's ASIC reverse-engineering challenge
A blogger with an engineering background details how they spent about a month reverse-engineering an ASIC chip design as part of a public puzzle set by trading firm Jane Street. The challenge involved analyzing a GDS chip-layout file to determine the chip's function, first through an easier warmup version with more design information, then a harder unaided version. The author has published their code on GitHub and plans follow-up posts explaining each technical step in more depth.
