Quartus 7.1 Sp1 and DSPBuilder 7.1Sp1

Hallo everyone,

I have a problem with my Installation. I have installed Quartus 7.1 Sp1 and DSPBuilder 7.1Sp1.

If I want compile any Example Model like "singen" an error occured.

The SignalCompiler shows the following message:

Created Quartus II Project C:\altera\71\quartus\dsp_builder\DesignExamples\Tutorials\GettingStartedSinMdl\singen_dspbuilder\singen.qpf

Generating HDL

Analyzing model...

Matlab Error

Java exception occurred:

java.lang.UnsatisfiedLinkError: checkOut

at com.altera.dspbuilder.portmanager.PortManager.checkOut(Native Method)

at com.altera.dspbuilder.serialisation.ModelSerialiser.<init>(ModelSerialiser.java:88)

Error during generation: Analyzing Error: See log for details.

Has anyone an idea who is the problem? or where I can found the log file?

So long

Mario

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!
