| File | What it is |
|---|---|
| `skr_findings.md` | Yosys synthesis of the whole design: RTL cells → generic gates, flip-flop flavours, why arithmetic evaporates |
| `FPGA.md` | Measured LUT/FF counts across iCE40, ECP5, Gowin, Xilinx 7-series, Intel MAX 10; device fit table; the 183-port-bit wrapper problem |
| `arch.md` | The artifact chain: SystemVerilog → sv2v → yosys/netlistsvg → OpenLane GDS → 3D view |
| `docs/schematics/*.svg` | RTL schematics per module, from yosys + netlistsvg |
| `gds/built/gpu.gds` | The OpenLane/SKY130 place-and-route result built locally (33 MB) |
| `tiny-gpu.edam.json` | Edalize project file for the sv2v output |
