Quartus 7.1 Sp1 and DSPBuilder 7.1Sp1

Ok, I've read carefully DSP Builder User Guide and found a source of a problem.

In Troubleshooting chapter I found the "DSP Builder StartUp Dependencies", checked all error possibilities and found this note:

"4. When Cygwin is installed, make sure that it is listed after Quartus in

the path. Correct environment settings in Cygwin do not guarantee

that Signal Compiler will start properly, as DSP Builder relies on

DOS settings rather than Cygwin. (When MATLAB is started from a

Cygwin command prompt window, system env in the MATLAB

command window only reflects the Cygwin settings.)"

and..

"5. If there are any other operation systems, such as WinVar, installed

on top of Windows, make sure that they are listed after Quartus in

the PATH environment variable."

I have Cygwin installed on my computer and when I done everything according to point 4, then DSP Builder started to work :)

Cheers!
