vim默認沒有systemverilog語法高亮，需要自己設置。網上不少方法，進行了總結。
1）linux系統
linux系統是多用戶系統，可以在系統配置文件中設置，設置對每個用戶都生效。也可以在/home/用戶名目錄下設置，只對本用戶有效（服務器場景）。
方法1：.系統配置文件（需root權限）
系統的語法配置路徑在：/usr/share/vim/vim72/syntax
在目錄 /etc/ 下面，有個名爲vimrc的文件，這是系統中公共的vim配置文件，對所有用戶都有效。而在每個用戶的主目錄下，都可以自己建立私有的配置文件，命名爲：“.vimrc”。
---> 將systemverilog.vim 複製到usr/share/vim/vim72/syntax目錄下
---> 在/etc/.vimrc中添加 au BufRead,BufNewFile *.sv set filetype=systemverilog
方法2：單用戶配置
--->在/home/用戶目錄下，創建.vim隱藏文件夾。
--->在.vim隱藏文件下，創建一個syntax文件夾
---->將將systemverilog.vim 複製到syntax目錄下
--->cd ~進入/home/用戶目錄，在用戶目錄下，創建一個.vimrc文件
在.vimrc中設置
set cursorline " 突出顯示當前行
set ruler " 打開狀態欄標尺
au BufRead,BufNewFile *.sv set filetype=systemverilog
--->source .vimrc
注： bshell 可能會報錯，但是命令生效了，具體原因，研究不深。
2)windows系統 ，
gvim設置，windows不能對列操作，ctrl+v無效。設置相同的道理。
