12. Managing Projects and Files
DSP Builder design requires the following files to store all the components:
The top-level Simulink model < top_level_name >.mdl
The import directory DSPBuilder_< top_level_name >_import and its contents.
Any source files for imported HDL.
Any Intel format hexadecimal memory initialization (. hex ) files.
Any referenced custom library files.
The analyzed Simulink model file < top_level_name >.mdlxml .
1
When you include the . mdlxml file in a Quartus II project, you do not need to call
MATLAB to synthesize the design. You can still synthesize a project without the
. mdlxml file, but you must call MATLAB as part of the generation flow.
If you do not want Quartus II synthesis to call MATLAB, or are passing the design a
user without access to MATLAB, follow one of these steps:
Include both the . mdl and corresponding . mdlxml files in the project,
Export HDL and specify the exported HDL as the source with no references to the
. mdl or . mdlxml files in the project.
1
Any design that includes HDL Import, State Machine Editor or MegaCore functions
requires the import directory.
Integration with Source Control Systems
Altera recommends that you store Quartus II archive (. qar ) files rather than
individual HDL files for source control purposes.
To create a . qar file, follow these steps in the Quartus II software:
1. Create a Quartus II project that sources the top-level Quartus II IP (. qip ) file that
the DSP Builder Export HDL flow generates ( “Exporting HDL” on page 12–3 ).
2. Perform analysis and elaboration to ensure the design incorporates any black-box
system files.
3. Archive the project by clicking Archive Project on the project menu in the
Quartus II software) to generate the . qar file.
1
Any HDL elements that you introduce into DSP Builder with custom library blocks
may require their own source control. Additional . qip files, which are referenced in
the "# Imported IP files" section of the top-level . qip file, list the required files.
