A couple of things.

First off, if you're going to use syntax highlighting, you should
really do it the way it's designed to work and not go off and do it
somehow differently. Rather than put an autocommand in your
~/.vimrc, just use

filetype on

and if you discover that Vim does not detect the systemverilog
filetype, then create a file named ~/.vim/ftdetect/systemverilog.vim
and put this in it:

au BufRead,BufNewFile *.sv,*.svh set filetype=systemverilog

Secondly, a BufEnter autocommand is triggered only when you enter a
buffer, not when you just display it. For example, execute this
command,

vim -Nu NONE --cmd 'au BufEnter * echomsg "hello" expand("%")' -O file1 file2 file3

then execute

:messages

You will see this:

"file1" 0L, 0C
hello file1
"file2" 0L, 0C
"file3" 0L, 0C
hello file1

If you then type Ctrl-W Ctrl-W twice and execute ":messages" again
you will see this:

"file1" 0L, 0C
hello file1
"file2" 0L, 0C
"file3" 0L, 0C
hello file1
hello file2
hello file3
