I was working with DSP Builder, but today I couldnt, because signal compiler doesnt work,
Many days before, I checked that quartus_map process run while signal compiler is running, but today I check the same process and the process is not using CPU usage. I was thinking that some modification suffer the java interaction but I not sure. Or could be path problems, but I already check and it is correct. If anybody have solved this problem, please helpme!!!Link Copied

I'll take your word for it on the CPU usage. It's a bit small for me to make out.
Do you do any Java development on your computer? Have you by any chance set the JAVA_TOOL_OPTIONS environment variable? (Use getenv in MATLAB to find out if you're not sure).- Mark as New

In this case the CPU usage is 0
Concerning to Java development, Im dont think so. I also downgrade the Java software, in order to check, but the problem was not solve. I ran the JAVA_TOOL_OPTIONS as a command in Matlab, but the result are the same with other computer that is running now. Thank you dabuk- Mark as New

Uninstalling Java would make no difference, since it's included as part of Quartus.
What exactly does the MATLAB command "getenv JAVA_TOOL_OPTIONS" give you? Anything other than an empty string could cause problems.- Mark as New

This is the result:
>> getenv JAVA_TOOL_OPTIONS ans = '' >> I think it is correct, because I have another computer running DSPBuilder. Thanks- Mark as New

Yes that looks fine. I can't think of anything else off the top of my head. Have you changed anything on your computer since it last worked?

I work everyday with the same computer, but I didnt do any change.
It is strange, because the problem stop the process of synthesis and. looks like if something left to continue. I compiled a program with quartus II and the process was normal. The problem is in the interface with DSP Builder. Today, I unistalled matlab, and DSp Builder, then I installed again. The problem continue. Thanks dabuk
