    1. FPGAボードを買った (Xilinx Kintex 7)
      By くりうず from kuriuzublog

      Xilinx Kintex 7 XC7K420T-2FFG901I

      某海外通販で買った。38000円くらい。

      評価

      付属ACアダプタ

      • 出力 12V 5A
      • 付属のACアダプタはプラグの形状が違うので日本では使えない
      • 変換器を用意すればたぶん使える（未確認）
      • DCプラグはよくある形なので日本でも同等規格のものを簡単に入手できる

      セラー

      • 発送が遅い
      • 発送が遅すぎるのでExtend Processing Timeで期限を7日延期する必要があった
      • 途中で春節に伴う休業と物流の遅延で届くのがめちゃくちゃ遅くなった。つらい
      • なぜか昼間に送ったメッセージの返信が23:00-2:00(UTC+8)頃に来る。生活リズム大丈夫かよ
      • 大量の基板の検品作業でクソ忙しいって言ってた

      基板

      • FPGAのGPIOで点灯できる16個のLEDのうち2個が点灯しない。ふざけんな
      • 検品作業でクソ忙しいって言ってる割には不良を見逃してるじゃねえか
      • 基板裏面の8ピンの発振器が斜めに浮いた状態ではんだ付けされていた
      • 実施できる範囲でテストしたけどLED不点灯以外は問題ないっぽい
      • 品質低いけど値段を考えれば許容範囲

      ドキュメントとか

      • 取扱説明書？マニュアル？そんなものはない
      • 回路図？そんなものはない
      • ピン配置を記載したExcelファイルをもらえる
      • 雀の涙ほどに充実したサンプルコードをもらえる
      • セラーに「関連ファイルよこせオラァ」するとダウンロードURLが送られてくる
      • サンプルコードを読み取って使い方を把握する能力が必要

      書き込み・デバッグ

      • JTAG書き込み機は付属しないので自分で用意する必要がある
      • XADCが正常に動いてないっぽくて、Vivado上でチップ温度が-273℃って表示されるんですがどうすればいいんですかね？

      その他

      • なんでこの値段で売れるの？
      • ボード価格がFPGAチップ販売価格よりも安い気がするんだけど、あっちの国ではどんな異常事態が起こってるの？
      • もしかしてマイニング特需の終焉と関係あったりする？
      • マイニング特需崩壊でグラフィックボードが安くなっててメッチャ嬉しい
      • ちなみに私は例のグラボ未所持です
      • ぼくも例のグラボでHDMI復活とかDP端子生やすとかやりたい
      • SFP+光トランシーバとDAC欲しい
      • QSFP DACとかQSFP→SFP+x4変換とか欲しい
      • QSFP光トランシーバは8芯光ファイバー用意するのが面倒そうなのでいいです
      • 1000BASE-T (GMII PHY)はつけてほしかった
      • SFP+光トランシーバとかはFiberstoreってところで買うのが安いっぽいですね

      おまけ
