Hello Guys,
I am using simulink on Centos system at the university and recently started using Altera DSP builder blocksets . I am facing a problem, whenever i try adding ports to the block through optional ports settings. I get this error and nothing reflects on the blocks. can somebody tell me what am i going it wrongly?warning: port number 1 specified in 'port_label' exceeds the number of input ports of 'untitled/counter' Regards, Dilip

"whenever i try adding ports to the block through optional ports settings" is pretty vague!
It sounds like you're using DSP Builder Standard rather than Advanced. It also sounds like in this example you've added a Counter block to your design and tried adding some extra ports to the block. I've just done the same and can't replicate the errors you're seeing. What may be happening though is that your paths are not set up properly or you may be running 64-bit MATLAB which is not currently supported. Please type the following at the MATLAB prompt: >> mexext This should print "mexglx" on MATLAB running on Linux. If it says "mexa64", you're running MATLAB in 64-bit mode. Start MATLAB with "matlab -glnx86" to force it into 32-bit mode. >> which sGeneric This should point to a file that ends in .mexglx. If it can't find it then your paths are not set up properly. >> javaclasspath -dynamic This should report that the file "dspb_sblocks.jar" is on the Java classpath. If it's not then your Java path is not set up properly. (In some cases it may be on the static class path in which case javaclasspath -static will show you this).- Mark as New

Thanks for helping me out. I tried all three commands and found out that I am running 32-bit Matlab version and "dspb_sblocks.jar" is listed on javaclasspath but when i have given >>which sGeneric, it can't find it. Please help me how to set the path correctly.
Altera has been installed on this directory. /sw/altera/quartus/9.0/quartus Regards, Dilip- Mark as New

In which case you should type the following commands:
addpath /sw/altera/quartus/9.0/quartus/dsp_builder/bin addpath /sw/altera/quartus/9.0/quartus/dsp_builder/bin/matlab addpath /sw/altera/quartus/9.0/quartus/dsp_builder/bin/mdllibrary To make sure these get executed every time, add them to a startup.m file as described in http://www.mathworks.com/help/techdoc/matlab_env/f8-4994.html (http://www.mathworks.com/help/techdoc/matlab_env/f8-4994.html).- Mark as New

Hi,
This path wasn't added before /sw/altera/quartus/9.0/quartus/dsp_builder/bin and now after adding it, i can add additional ports to the blocks. Thanks a lot. Regards, Dilip- Mark as New

Hi,
I can see that there are some blocksets missing in altera dsp builder advanced blockset. Now i can onle see base blocks. where are those boards and all. Thanks, Dilip- Mark as New

Sounds like your path is missing lots of stuff. Try adding further directories:
addpath(genpath('/sw/altera/quartus/9.0/quartus/dspba'))
Will add every directory under DSP Builder Advanced to your MATLAB path and so you shouldn't miss anything. You could make it more fine-grained with that if that was too much.

No that isn't helping. when i right click alter dsp builder advanced blockset, i can open this library called aionmodelip. Where it shows all the other blocks like boardsupport. But these things aren't shown on simulink library browser.

I don't think that's ever worked. Ignore that.

I just deleted the repository and rebuild it again. Now everything seems to be normal :)
