Once your vhd file is ready you can convert it into a Block Symbol FIle with
File>Create/Update>Create symbol files for current file.
After the symbol generation you will find the symbol in your Project folder and you will be able to insert it in your top-level bdf file by double-clicking on the sheet and choosing the symbol that you have created before.

Thank but I already know these:
I've design a.bdf with this approach form a1.vhd......a5.vhd
and b.bdf with this approach form b1.vhd.......b6.vhd
and now I want to use a.bdf and b.bdf in my top-level.bdf schematic.
my problem is I've had a lot of vhd files I want to draw my top_level.bdf form two three sub_schematic.bdf ....
is it possible? or I have to draw all block individually in my top-level.bdf?
P.S.if there is not possible so it's a good offer for next version of quartus.
