Hierarchy in Schematic-VHDL Design

Hi,



in QuartusII v4.2 SP1 I have the following problem:



My top level file is a schematic file called "H_top.bdf"



In this top level file I have several symbols, for example "cache_search.bsf".



The component cache_search is also a schematic file from which I created a .vhd file in Quartus so that I have one "cache_search.bdf" and one "cache_search.vhd" which are of course identical.



Now in my top level file I include under PROJECT --> ADD/REMOVE FILES IN PROJECT the file "H_top.bdf" Under USER LIBRARIES I include the directory in which the "cache_search.bdf" and "cache_search.vhd" are included.



When I click on the symbol "cache_search.bsf" in the top level schematic "H_top.bdf" file the "cache_search.vhd" is opened. I would like to choose whether to look at the "cache_search.vhd" or the "cache_search.bdf" ...



How can I do that ?



Any suggestions are appreciated.

When you diuble click on a symbol in the bdf the behavior is to open the design file that was used as part of the compilation. In this case it was the file with the vhd extension (as a vhd extension has a higher priority than a bdf extension). If you want to open the bdf instead do a File Open, traverse to the directory which has te bdf file and open it.

If you want the bdf file to be used for compilation, add the bdf file explicitly to the file list.

Hope this helps, Subroto Datta Altera Corp.
