Hi all, I'm designing a network of processor (Nios II) with Qsys 11.1. There are 32 niosII in my design and I use the ip-generate command-line. The issue is Qsys can't generate the sopcinfo file: --- Quote Start --- Info: system: Done system" with 98 modules, 4296 files, 88115683 bytes Error: Error writing sopcinfo report java.lang.OutOfMemoryError: Java heap space Info: ip-generate succeeded. Info: Finished: Create HDL design files for synthesis --- Quote End --- Anyone has idea? Thanks! ps: I tried to close and reopen Qsys

Try to configure your JVM with more memory

Thank you Aprado for this quick responce. But I'm not very confortable with Java. Could you tell me where and how configure my JVM correctly? Thanks!

Google "configure jvm more memory" It's pretty straight forward

ok I tried to find a solution to configure the JVM. the switch to expand java heap size memory is -Xmx2048m where 2048 is the size of maximum heap memory I want to allocate. The issue is where can I use this switch? In some examples I saw this switch is used like a parameter of the application. The application that I want to expand heap size memory is ip-generate. So I tried with a command-line like that: ip-generate -Xmx2048m --project-directory=D:/myproject --output-directory=D:/myproject/synthesis/ --file-set=QUARTUS_SYNTH --report-file=sopcinfo:D:/myproject/system.sopcinfo --report-file=qip:D:/myproject/synthesis/system.qip --system-info=DEVICE_FAMILY="Stratix IV" --component-file=D:/myproject/system.qsysBut it makes an error: --- Quote Start --- Error: Unrecognized switch Xmx2048m --- Quote End --- I forgot to specity that I'm working on windowsXP-64bit and so I use NiosII 11.1 command shell to launch this command-line. Thanks for your responce.

I'd guess ip-generate is some kind of wrapper ?? You need to find the incantation that acually runs the jvm itself. If you type at the shell prompt: $ type ip-generate the shell should tell what it executes when you run ip-generate.

I pinged someone about this and they believe what is passed by ip-generate will overwrite the global setting. So if the global doesn't work I think hacking the .exe will be your only option (for now, it's being looked into)

Do you think modifing the ip-generate.exe could change NiosII rights of the license ?

I'm not really sure. I think the lawyers have better things to do than pursuing someone who hacks a fix into an .exe file though :)

Hello - has anyone come up with a better solution to this then hacking the executable?

I am running the Quarts 11.1sp2 tools under Linux and am getting the same JVM error as reported earlier:

( Error: Error writing sopcinfo report java.lang.OutOfMemoryError: Java heap space java.lang.OutOfMemoryError: Java heap space)

Thanks
Kevin.

As an update, this is listed as an SPR (spr362079). I have seen that a large QSYS system gets the OutOfMemory error from the JVM in using either ip-generate or the GUI. Paring the system back by some number of components resolves the error but not the problem.

I am hoping that Quartus 12 will solve the problem.

FYI, ip-generate (I guess that it was changed in newer versions) in Quartus 13 has a --jvm-max-heap-size=<value> parameter
