5. Double click on the System Generator Token and verify that the Compilation option is
set to HDL Netlist. Click Generate.
A folder named hdl is created inside the example7 folder.
6. Open the hdl folder and notice the file named encrypted_hdl_import.vhd. Open
the file to see that this is the encrypted file that was netlisted separately.
Note:
The file encrypted_hdl_import.vhd is for simulation purposes only. If you want to netlist
this design for implementation, you’ll need to include another addFile line in the configuration file that
specifies the NGC file that is created by Core Generator. Refer to the tutorial
Black Box Tutorial
Example 2: Importing a Core Generator Module that Needs a VHDL Wrapper to Satisfy
Black Box HDL Requirements for an example of how to do this.
