Vivadoの開発環境とOpenCoresの開発環境が準備できましたので、いよいよFPGAのコンフィグレーションを行います。
bitstreamを作る
FPGAに書き込むためのbitstreamを生成します。実はbitstreamはOpenCoresのページにも用意されているのですが、試しにmakeをしてみたら簡単にbitstreamができたのでこちらを使いました。
ここでは生成までのログを参考までにそのまま掲載します。ログを見ると内部でVivadoが使われているのがわかります。

この.bitファイルがFPGAのコンフィグレーションに使われるファイルです。
FPGAにbitstreamを書き込む
先ほど作成したbitstreamをFPGAに書き込みます。こちらもmakeするだけです。実行時のログをそのまま掲載します。

これでARTY FPGAボードがPDP-11になったはずです・・・。（たぶん）
いよいよUNIX V5を動かしてみます。
