DSP Tools

Dear All!

I'm trying to do a hardware co-simulation of a System Generator model in the MATLAB software.

The modul contains a Black Box element (VHDL files) .
These VHDL files use an additional library:

LIBRARY MY_LIBRARY;
USE MY_LIBRARY.ALL;

 
How is it possible to add the library to the model?
At the moment the synthesis tool (xst) called by MATLAB (system generator block -> generate) reports an error on:
ERROR:HDLParsers:3317 - "path/file.vhd" Line 1790. Library MY_LIBRARY cannot be found.

I'm able to add the library manually in the generated ISE but this unfortunately doesn't solve the problem because every time I click the "generate" button in the System Generator model, a new ISE project  is generated, the library is lost and the HW co-simulation doesn't work.
 

Thanks very much!

I don't think a user defined library is supported in SysGen blackbox flow. Everything needs to be in the "work" library.

Does this limitation still hold in ISE13.1? 

I have Synplicity generated VHDL that uses a separate library, so blackbox will be eliminated as an option for me if I can't pull in a separate library.  I have already experimented with modifying the code to use a single library for a different tool flow but it isn't guaranteed to be free of name conflicts in that case.

Within the System Generator Help (within Matlab) I find the document titled "Importing HDL Modules: Black Box Configuration M-Function".  This help document includes a heading on Black Box VHDL Library Support and describes how to compile files into a user library and include the libraries for use in black box code.

Thanks for pointing this out. Yes, VHDL Library Support for Black Box Import is a new feature added in 13.1.
