根据别人的插件修改了一下：）

下载地址：http://bb2hh.blogbus.com/files/12271773140.vim

只要了几个功能：）

更新了下，把begin放在了下面。

同时增加了一个功能。就是按下保存会自动修改Last Modifited的时间：）比较实用：）使用此功能在启动文件中加入：autocmd BufWritePre,FileWritePre *.v   ks|call LastModified()|'s

vimrc中修改调用命令的快捷键：

:inoremap    <A-a>  <ESC>:Allpn<CR>
map          <A-a>  :Allpn<CR>
:inoremap    <A-c>  <ESC>:Allcom<CR>
map          <A-c>  :Allcom<CR>
:inoremap    <A-z>  <ESC>:Aheader<CR>
map          <A-z>  :Aheader<CR>
:inoremap    <A-l>  <ESC>:Acontent<CR>
map          <A-l>  :Acontent<CR>
 

1.当输入<=的时候会自动将<=改成<= #1，

2.当按下Alt+z（可以自己在vimrc中修改）的时候会自动加入会自动加入头信息，如下：

 可以去下载的vim插件中，修改头信息：）

当修改完以后，按下保存，或者自己设置的保存热键，会变成如下：（修改时间自动调整）

3.当按下Alt+a的时候，会自动生成时序电路的always

这里要首先声明本module的clock和reset，不支持多时钟：）

 当按下alt+c的时候会自动生成组合逻辑的always：）

按下alt+l会自动加入注释
