DE0 nanoのjtag-uartにtelnetで接続する

FGPA

DE0 nano用のシリアルUSBケーブルを買うのが億劫だったので調べていたら
jtagサーバにtelnet接続するソフトウェアを書いている人がいた。
https://github.com/binary-logic/vj-uart

使い方：
1. https://github.com/binary-logic/vj-uartのrtlフォルダに有る.qpfプロジェクトをquartus2で立ち上げる
2. コンパイルしてDE0 NanoにProgramする
3. コマンドプロンプトを開く。あらかじめPATHにquartusのインストールディレクトリを通しておく(binフォルダ)
quartus_stpコマンドでTcl用のシェルを立ち上げる(quartus_shコマンドだとできない)

$ quartus_stp -s

4. sourceコマンドでTclスクリプトを読み込むとJTAGサーバが起動する
（たぶんQuartus2のProgrammerを消しとかないといけないと思う）

$ source vjuart.tcl

5. Tera termから127.0.0.1, telnet, 2023番ポートを指定して接続する

実行結果

C:\Users\shohei\Downloads\vj-uart-master\vj-uart-master\bin
λ quartus_stp -s

後々使いそうなのでショートカットを作った。
プロパティのターゲットに

C:\altera\14.0\quartus\bin64\quartus_stp.exe -t C:\altera\14.0\vj-uart\bin\vjuart.tcl

を指定すればショートカットのダブルクリックでJTAGサーバが起動する
