Step 5: NAS destination folder

Summary

The step 5 of the OpenNAS wizard allows the user to select the destination folder in which the NAS VHDL files will be generated. In that folder, the NAS top file will be generated according to the parameters set on the previous wizard's steps. Furthermore, others VHDL files dependencies will be copied, and a custom constraints file will be also generated.

Selecting the destination folder

Create a NAS folder architecture

Although this is not mandatory, it is recommendable to create a folder hierarchy to separate the source files and the project files. And also it is recommendable to create this structure in a place with a short path, due to long paths could not work with the Xilinx/Intel FPGA tools when the files need to be added to a new FPGA project.

This way, if the current directory is C:, we should have the following hierarchy:

• NAS_PDM_64ch_cas_aer
  • Sources
  • Project

Select "Sources" folder

By clicking on the "Browse Folder" button, navigate to C:\NAS_PDM_64ch_cas_aer and, once there, select "Sources" folder. Click on the "Ok" button. In the path textbox, you will see the absolute path of the destination folder. To finish the OpenNAS wizard, click on the "Finish" button to generate and copy the files. If the process success, a new message window will appear with the text "OpenN@s successfully generated". If not, a warning message will appear with the error.
