Could you build this?
No Reverse-engineering proprietary FPGA bitstreams requires deep hardware engineering, silicon architecture knowledge, electronic design automation (EDA) experience, and specialized fuzzing rigs.
What it would actually take: Documenting and decoding closed FPGA bitstream formats (such as Xilinx or Lattice) requires differential fuzzing with vendor toolchains, mapping bit positions to programmable interconnect points (PIPs) and configurable logic blocks (CLBs), and validating against open-source place-and-route tools (like Project Trellis/NextPNR). This requires deep hardware engineering expertise, knowledge of VLSI and digital logic architectures, and hundreds of hours of automated hardware fuzzing across physical silicon testbenches.
Discussion
4 comments analyzed.
Competitors mentioned: Qwen, Gemini
Concerns raised: Claude Code credits are expensive, Hallucination control needed for task reliability, Claude gets stuck in locally optimal solutions, Gemini produces scattered work without independence
Feature requests: Better handling of feedback from multiple LLMs, Ability to incorporate suggestions from other models without contradiction
