Combine DSP Builder and Quartus II Project

Thank you for you answer!

I included a small self made and compiled dsp builder project in an empty quartus II project. I used the tcl command line and executed the "source <file directory>/*_add.tcl" file, which was generated from simulink.

Then I had, as you mentioned, the *.mdl and *.mdlxml files in my quartus Project. I compiled it and afterwards I saw all the vhd files in the Hierarchy. But in the File Window there were only the mdl and mdlxml files.

Do I have to import the generated vhd files from the <project>/db directory manualy then? Do I have to create symbols then for each vhd file?

In the end I would like to have a schematic as top level entity file where i can integrate the dsp builder project (or parts of the project) as black box.

I think I still make a mistake somewhere.
