9.1's been around for a while and I've not heard of this problem before. Is there any CPU usage while this is happening?Assuming no other Quartus process is currently available, is there one running at the point that it's stalled? Do you have an environment variable set called JAVA_TOOL_OPTIONS? (use getenv to query it in MATLAB).
Means it's not set. Was a long shot. If this variable was set it could make Java stall on startup waiting for a debugger to attach. It's irrelevent anyway if you see no Quartus process running in the task manager.One other thing you could do is make sure that Quartus is on your windows path, although I would have thought DSP Builder would give an error if it couldn't find it.
The path for both is the same, ie, c:/altera/quartus.Do you think that re-installing the software would help? I am working in my school's lab, but i think i'll be able to convince them.
Hi,I kind of figured something out, just wanted to update you with it. DSP builder v9.1 is not compatible with Matlab 2009b. http://www.altera.com/support/ip/dsp/ips-dsp-version.html Thought i am having the same problem with DSP Builder v10.0, now i am gonna try degrading the version of matlab.
