Select library per file in QSys Component

Altera_Forum · ‎06-12-2015

Hi

I am using a commercial IP which is encrypted. The IP is spread into different libraries (in VHDL example code explicit libraries are accessed) and I am creating a _hw.tcl file in order to plug it into QSys. The problem is that I haven't been able to find a method to enforce a library name on a per-file basis.

Example: I have two files (encrypted) in different files.

add_fileset_file buffer.vhd VHDL PATH ip/lib1/buffer.vhd

add_fileset_file stream.vhd VHDL PATH ip/lib2/stream.vhd

The files depend on each other but they need to lie in different specific libraries. Synthesis fails when I do not explicitely select that. How do I tell Qsys the library per file?

Unfortunately, I could not find any such an option in the QuartusII handbook neither in the TCL reference nor in the GUI.

BTW, I am using QuartusII 15.0.

Thanks a lot

Qsys does not support libraries but there is a workaround for Quartus.

Thanks

Hi Korom,

Can you please file a Service Request with Altera and ask them this question. I'll tell you my solution, but it would be useful to know Altera's official recommendation.

Rather than use add_fileset_file and pass it file names I use a generate statement. That generate statement creates the top-level component wrapper and a .qip file. The .qip file can use VHDL include statements with library files. I've attached an example script. It doesn't include the code, since I just quickly zipped those files. If you want a fully functional Avalon-MM slave component, let me know, and I'll spend a little more time creating an example.

Cheers,

Dave
