Honored ContributorDo you have other version of Quartus installed on your machine? Might be that it is still associating with your older version of Quartus... There are several things you can check:
- QUARTUS_ROOTDIR environment variable... make sure that's 8.0 as well - Just fire up Quartus 8.0 first, before launching your DSP Builder... this changes your the internal registries associated with the Quartus... - Type ver in Matlab command prompt, making sure that you do have the correct 8.0 version DSP Builder running... - You can always try re-set up the megacores from inside DSP Builder (typing "alt_dspbuilder_setup_megacore" at Matlab command prompt). - If you had an older version of Quartus/DSP Builder before, might be possible that your IP cache folder is corrupted... In that case, delete .altera.quartus folder from your Document and Setting folder (should just be located in C:/Document and Setting/<your user name>... and then restart Matlab and DSP Builder... - Can always try uninstalling and reinstalling DSP Builder... Please feel free to add to this post if you know others methods that Dan should try...
