VHDL 2008, DSP Builder and Quartus 10

Hi

I installed Quartus and DSP Builder v10 today and am already having trouble. In the sensitivity list for some of my processes in my hand written code I use the 'all' keyword, which apparently is only valid for VHDL 2008. From within Quartus I simply change the VHDL version in project settings and all is well. However I cannot now compile similar blocks in DSP Builder in Simulink (via the Import VHDL block) as I think VHDL 1993 is being assumed when Quartus is called to generate the SIMGEN stuff... as such none of my projects can now be compiled in DSP Builder / Simulink. Is there a way to set VHDL 2008 as a default in Quartus 10 or to tell Simulink DSP Builder v10 to tell Quartus 10 to use VHDL 2008?

Many thanks, Kurt

    Or, if you want to make VHDL-2008 your default VHDL version for all your VHDL files, you can add the following line in your QSF: 

    set_global_assignment -name VHDL_INPUT_VERSION VHDL_2008

    This can also be done in the GUI:

    Assignments > Settings > Analysis & Synthesis Settings > VHDL Input

    and choose "VHDL 2008" under VHDL Version.

    However, do note that not all VHDL-2008 features have been implemented.

    Many thanks indeed!!!

    Adding:

    -- synthesis VHDL_INPUT_VERSION VHDL_2008

    as the first line of my hand-coded VHD files worked perfectly.

    Kindest regards, Kurt

    excellent, this should probably go into the DSP Builder manual. i don't think the default QII VHDL version will change anytime soon (new keywords), so it would be useful to know how to control it manually

    this looks good for a Quartus II project, but i'm not sure that'll help in HDL Import in DSP Builder

    Not too sure about DSP Builder, but that's the way to do it if you want to set VHDL-2008 as the default in Quartus.
