VHDL 2008, DSP Builder and Quartus 10

[Altera_Forum]

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

try the VHDL version synthesis directive:

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

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.

hi guys anyboy knows how to implemente the SDRAM in DSP builder?? 

thanks!!!
