README
README.mdFPGC5
My big project, basically started in July 2019 as FPGC3 (versions 1 and 2 do not count). Project exists to learn more about the fundamentals of computers and to improve my Verilog skills, while also designing my own "environment" (PCB, Compilers, OS, etc.) around it.
FPGC is a completely self designed computer, implemented in an EP4CE15 FPGA.

Questions
How big is the FPGC4IOboard PCB?
It measures 91.4 × 102.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the FPGC4IOboard use?
150 parts, built around the CH376T, ADA4841-1YRJ, CH340G and W25Q128JVSIQ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the FPGC4IOboard KiCad files?
From the bartpleiter/FPGC5 repository on GitHub, at the commit this page was made from: the board is PCB/FPGC5IOboard/FPGC4IOboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the FPGC4IOboard design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
