(WIP) NES emulator running on FPGA implemented in scala(w/ chisel)

Chisel NES [](https://github.com/shino-hinaduki/chisel-nes/actions/workflows/test.yml) =======================

以下のコマンドでscalaのprojectをビルドして、Chiselから生成したVerilog file dst/ChiselNes.v を得る。

eda/quartusprimelite21.1/chiselnes.qpf` を Quartus Primeで開き、Compile Design を実行して論理合成した後、Program Deviceで書き込む。

(先の手順で生成した dst/ChiselNes.v がtop-level design entityに指定されており、プロジェクトにはその他IPや制約ファイルなどが含まれている)
