The project includes a custom RISC-V compatible CPU (RV32IMC), a raster graphics pipeline, display controller, bus fabric, memory controllers, and a full PCB layout in KiCad. The design is written in synthesisable Verilog 2005 and targets the iCE40-HX8k FPGA using an open-source toolchain (Yosys, nextpnr, Project Icestorm). The processor passes the RISC-V compliance suite and riscv-formal verification. The repository includes simulation flows, synthesis scripts, software tests, and detailed documentation. ## Full article daily.dev links to this article rather than hosting it.
