Hey there, Have you checked out the trouble shooter section of the DSP Builder User guide? I believe the section titled "Synthesis Flow Does Not Run Properly" (page 13-3 of the version 7.2 user guide) should help.

Thanks for caring. Do you mean i should check environment variable? :) .I am sure that all required environment variables are already set correctly.

Right check environment variable and matlab path... 

 

Also possibly delete the IP cache folder (the .altera.quartus folder under C:\Document and Settings\<your user name>\)... sometimes it gets corrupted and causes problems...

Hey, wronghorizon, you have just helped me solve an SoPC builder problem I have been chasing for a week. 

 

The above 'fix' cleared up an issue I was having in my SoPC system not seeing all the DDR2 newer memory controllers in the SoPC componenet list. 

 

Thanks.

Glad that helped Avatar. I experienced the same problem when I moved from 7.2SP1 to 8.0. Someone ought to document that.

Make sure that you don't have any residual DSP Builder blocks residing in the _import directory (or any of the other directories w/in the project). I had an issue like this in which there were multiple versions of certain FIR filters (but I was only instantiating one of them in the actual MDL file). When the <module_name>_add.tcl file is run in Quartus, it basically looks for any .tcl files in any of the directories and tries to run them. In this case, I traced through the errors in the processing window, and it was trying to load blocks that weren't necessarily valid, just because there were files leftover. 

 

Hope this helps.

Hi wronghorizon and jjcannon, 

 

I have tried both of your suggestions. I still have the error: 

 

"Error: Failed to create Quartus II project FIRFilter in directory D:\altera\11.0\quartus\dsp_builder\Filter and Data Synchronization\FIRFilter_dspbuilder. 

Error: Error during compilation: Failed to update Quartus II project settings" 

 

when I try to compile with Signal Compiler. Do you have any other suggestions? 

 

To nguyenthehoang, 

Did you ever find a solution to this problem? 

 

Thank you all,

Hi, 

In my case the problem was resolved by removing the spaces from my project folder name. This was confusing the Signal Compiler. 

Best Regards,
