Problem : DSP builder simulink block installation into MATLAB simulink.

Dear friends, 

I am working on image proccessing project for that, i need to install DSP builder simulink block into MATLAB simulink. 

I have license version of altera 7.1 suit and MATLAB R2009b. 

I tried 4-5 times to install both. 

In first trial, I installed MATLAB first and than DSP builder. 

In second trial I installed DSP builder first and than MATLAB. 

But problem is that its' blocks are not shown into simulink every time. 

Once I formatted my PC,too. But it didn't work. 

I read installation guide of DSP builder and run command 'alt_dspbuilder_setup_megacore' 

in MATLAB, but it didn't worked. 

I read installation guide of DSP builder.It says that you need to make matlab folder READ only. but how it possible to make it read only,if I first install DSP builder? 

Give my clear way for DSP builder installation. 

Regards, 

Ronak Shah.

No you need to make sure the matlab folder is NOT read-only. DSP Builder needs to write to <MATLAB>/toolbox/local/classpath.txt and <MATLAB>/toolbox/local/pathdef.m where <MATLAB> refers to the directory where you installed MATLAB. Just use file explorer to go that directory and modify the file permissions. Or re-install MATLAB and don't tick the box that says make the files read-only - I think that exists, but it's been a while since I installed MATLAB. 

 

On the other hand I doubt DSP Builder 7.1 will work with MATLAB R2009b.

It's still not working. 

I have checked for dsp builder 7.1 and matlab 7.5.

MATLAB 7.5 is R2007b, I believe. The supported versions are R14 SP3, R2006a, R2006b, or R2007a (according to http://www.altera.com/literature/rn/rn_dsp_builder_71.pdf). 

 

Next option is to try to set up your classpath manually. Go to <MATLAB>/toolbox/local/classpath.txt and load it into a text editor. At the bottom of the file, there should be something like: 

 

# DSPBuilder START 

<quartus_path>/dsp_builder/bin/dspb_sblocks.jar 

dummyline 

# DSPBuilder END 

 

If these lines aren't there, then add them substituting the correct path for <quartus_path> as you go. 

 

Next, restart MATLAB and type "cd <quartus_path>/dsp_builder/bin/matlab". Then then type "setupDSPBuilderPath install <quartus_path>/dsp_builder/bin <quartus_path>/dsp_builder/bin/matlab <quartus_path>/dsp_builder/bin/mdllibrary". (substituting for quartus_path as before). That should finish with out errors and finally print "DSP Builder path saved." if it worked correctly.

Thanxs, 

DSP builder blocks are installed ok.All DSP .mdl are opening in matlab fine,it give some error mentioned in picture1.wat r they? 

But it gives me error when I run it, as an example when I run singen.mdl from DSP builder example it gives Err(perhaps java is not running), as attached picture below picture2.:):)wat r they?how to remove them?

I have no idea what that file is, but it's not a zip archive and even if it was, it would be better to just upload it as a picture file like png or jpg.

Myself Sumanta is facing a problem regarding the installation of Altera (Quartus II) toolbox in Matlab (r2013a). I have installed Quartus 9.1, but as mentioned the mentioned lines - 

# DSPBuilder START 

<quartus_path>/dsp_builder/bin/dspb_sblocks.jar 

dummyline 

# DSPBuilder END 

 

are not there in the Matlab path (<MATLAB>/toolbox/local/classpath.txt).  

 

On using the command -  

1) (cd <quartus_path>/dsp_builder/bin/matlab), the error is coming as - (Error using cd, Cannot CD to <quartus_path>/dsp_builder/bin/matlab (Directory access failure). 

 

2) (setupDSPBuilderPath install <quartus_path>/dsp_builder/bin <quartus_path>/dsp_builder/bin/matlab <quartus_path>/dsp_builder/bin/mdllibrary), error is - (Undefined function 'setupDSPBuilderPath' for input arguments of type 'char'.) 

 

3) (cd <quartus_path>/dsp_builder/bin/matlab), error is - (Error using cd, Cannot CD to <quartus_path>/dsp_builder/bin/matlab (Directory access failure). 

 

Please suggest me for some solutions.

You've not substituted for <quartus_path>. Since you could install quartus anywhere I had to give generic instructions with placeholders.

You need to start MATLAB through the "dsp_builder.bat" file inside the dsba folder

i've got the same problem and i sloved it just now. you can try this: in window os,start->all programmer->altera->dsp builder->start in matlab 20XXX.then you may see the dsp builder library. 

good luck
