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.

    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.
