Honored ContributorDSP Builder license
hi i have cyclone II kit EP2C70 with quartus II, dsp builder and nios II all v6.0.
i download .dat file from the licensing site of altera. my quartus II issue is resolved with that file. but when i run signal compiler from dsp builder. then messages appear in the "signal compiler messages window" that "unable to check a valid DSP Builder license". when i run synthesis then quartus II analysis & Synthesis remain unsuccessful.. what i should do? i need suggestion18 Replies
Altera_ForumI think so. What's probably happening is that DSP Builder is actually using your 10.0 quartus version but you should make sure that the Quartus directory on your Windows path points to the 10.0, or you may find there are DLL linking problems. That may be the cause of your problem.

Sorry i have been working on this problem for 2 days and my mind isn't with it anymore. What do you mean sir? i am going to downgrade my quartus 10.1v (uninstall it) to 10.0v so dsp_builder 10.0v can work like you said. Therefore, all the software should be compatiable (including matlab R2008). Then use my licese.dat

Yes, I'm saying downgrade your quartus.
I'm not saying it will fix your problem, but even if you could get your license problem to go away, DSP Builder 10.0 would not generate correctly with Quartus 10.1. - Altera_Forum
my license error is still occuring. what can i do to fix this?
- Altera_Forum
Did you update LM_LICENSE_FILE after downgrading? You had your license file at C:\altera\10.1sp1\license.dat before. Does that still exist?
Unfortunately I can't think of any other reason why your license file might fail. - Altera_Forum
I didn't know the versions had to be the same. Pretty sure I've used different versions together in the past.
- Altera_Forum
It's not been possible to mix versions since before 7.1. You could use the generated HDL from one version (using HDL Export) and add that to a project which you compiled with a different version of Quartus. DSP Builder is installed directly into quartus and can only be installed into a version that's the same as it.
