Problem with Dsp builder

[Altera_Forum]

Hi: 

 I have a problem with Altera Dsp Builder; I tried to run a demo but when I opened the mdl file (on MATLAB simulink) a lot of blocks appeared with the label "bad link" and obviously the simulation failed.  Would someone please tell me what can i do?  Thanks  PD: I have the MATLAB 7.2 version

Have you run all the install commands for DSp builder in Matlab? They are described in the release notes doc.

Hi Luis, 

 I've had the same problem when trying to load old examples dowloaded from altera web site. I suppose it was becasuse some of those projects were developped with older DSPbuilder version. Try to load whith any error the examples from your installed DspBuilder.
