Zilog Z80 CPU – Modern, free and open source silicon clone
Z80 open-source silicon. Goal is to become a silicon proven, pin compatible, open-source replacement for classic Z80. - rejunity/z80-open-silicon
It is a time for open-source and hardware preservation community to step in with a Free and Open Source Silicon (FOSS) replacement for Zilog Z80. Add thorough instruction (including 'illegal') execution tests ZEXALL to testbench Compare different implementations: Verilog core A-Z80, Netlist based Z80Explorer Tapeout with ChipIgnite in QFN44 package Tapeout with DIP40 package Create gate-level layouts that would resemble the original Z80 layout, see the original chip dies below. Tiny Tapeout is an educational project that aims to make it easier and cheaper than ever to get your digital designs manufactured on a real chip.
