DSPbuilder 7.2 and Matlab 2007b

Hi folks,

I am running Quartus 7.2, Megacore Library 7.2 and DSP Builder 7.2. Matlab is 2007b.

I'm trying to walk through the "singen" example. Everything works fine unitl I try to generate HDL. The model simulates in simulink and I get the expected waveforms. But when I bring up the DSP Builder dialog and hit "compile" I get:

Info: Generating HDL

Info: Analyzing Simulink model

Info: Analysis was successful

Info: *******************************************************************

Info: Running Quartus II Analysis & Synthesis

Info: Version 7.2 Build 151 09/26/2007 SJ Full Version

... BLAH BLAH BLAH ...

Info: Processing started: Thu Nov 29 18:29:25 2007

Info: Command: quartus_map singen

Error: IP Generator Error: Entity 'alt_dspbuilder_clock' (Version latest) not found in librarian.

Info: Found 1 design units, including 1 entities, in source file ../singen.mdl

Info: Found entity 1: singen_Interface

Error: Top-level design entity "singen" is undefined

Error: Quartus II Analysis & Synthesis was unsuccessful. 2 errors, 0 warnings

Info: Allocated 802 megabytes of memory during processing

Error: Processing ended: Thu Nov 29 18:29:29 2007

Error: Elapsed time: 00:00:04

Error: Error during compilation: Synthesis failed

So what gives? Is this due to Matlab R2007b? The DSP Builder manual only shows up to R2007a for compatibility. I'd hate to go back to R2007a just for this.

Any help will be greatly appreciated!

    To answer my own question:

    It is Matlab R2007b. When I rolled back to R2007a, everything works fine.

    Soo, if any Altera people are around, any plans for a fix?

    My Altera Sources tell me that to call it a fix is not quite right.

    Nothing is Broken, you just are using a version fo the MatLab tools that are not supported yet.

    File an SR with Altera and asks them when R2007b will be supported and let us all know what the answer is.

    Thanks

    I've rolled back to 2007a and I'm still getting the error.

    Any ideas?

    Yes, I had the same problem. It looks like there is some leftover stuff, somewhere (dll, registry?) and rolling back doesn't fix it.

    In my case, I had to reinstall the OS :mad: and then do a clean install of matlab (2007a) and altera.

    PITA but it worked.

    Good luck!

    That would be a MAJOR PITA; I have WAY to much stuff on this machine to think about that one. AAARRRGGG

    Did you ever hear anything from Altera as to when they will support 2007b?

    I have a feeling your ip cache directory has become corrupt.

    In your windows user directory (should be something like C:\Documents and Settings\<username>), you should have a directory called .altera.quartus, which in turn contains a directory called ip_cache. Try deleting this cache directory and retrying with 2007a.

    Hi,

    the same problem appears by walk through the "singen" example with:

    Quartus 8.0, DSP Builder 8.0 and Matlab R2008a

    Deleting the ip_cache directory has fixed the problem!

    Thanks, BerndS

    Hi,

    I have the same problem with Quartus 8.0 SP1, DSPBuilder 8.0 SP1 and Matlab 2007b. But in my case deleting the "ip_cache" directory doesn't help.

    I'm already in contact with Altera Support. Hopfully they can help me to find the reason for my problem.

    If there is a solution I will let you know.

    Best Regards,

    I just experienced the same error message after doing a fresh install of all the tools and trying to synthesize one of my designs.

    Like BerndS, I can confirm that deleting the ip_cache solves the problem, at least for the "Quartus 8.0, DSP Builder 8.0 and Matlab R2008a" setup.

    Maybe the install was not as clean as I thought.. I think at least Quartus was installed while logged in with a different user name than I am using now.

    In any case, thanks to dabuk for solving this issue.

    Regards,

    Nico.
