リバースエンジニアリングしてゲートレベルで再現したZ80ということらしい。すごすぎ。 A-Z80 CPU

is a conceptual implementation of the venerable Zilog Z80 processor targeted to synthesize and run on a modern FPGA device. It differs from the existing (mostly Verilog) Z80 implementations in that it is designed from the ground-up through the schematics and low-level gates. It is a result of a research and tedious reverse-engineering of Z80 at all levels, including micro-photographs of a die. Project includes a fully working Sinclair ZX Spectrum implementation based on this CPU. It has been described in more details at
