gvim tags如何支持systemverilog

1 tags文件的格式

在gvim中敲:help tag可以查看tag的介绍，里面讲了tags的文件格式。

The first lines in the tags file can contain lines that start with
    !_TAG_
These are sorted to the first lines, only rare tags that start with "!" can
sort to before them.  Vim recognizes two items.  The first one is the line
that indicates if the file was sorted.  When this line is found, Vim uses
binary searching for the tags file:
    !_TAG_FILE_SORTED<Tab>1<Tab>{anything} 

第一行可以为:

!_TAG_FILE_SORTED<Tab>1<Tab>I am a tags file.

第二行可以为：

!_TAG_FILE_FORMAT<Tab>1<Tab>/exxtend format; --format=1 will not append;" to lines/

正文的内容格式：

1.  {tagname}        {TAB} {tagfile} {TAB} {tagaddress}
2.  {tagfile}:{tagname} {TAB} {tagfile} {TAB} {tagaddress}
3.  {tagname}   &
