Quartus 11.0 Web the MegaWizard can not instanciate ALTLVDS_TX _RX functions

On Windows XP 32bit Pro I get "could not open the java virtual machine" error after clicking Next on Page 2a of the Megawizard. This happens consistently for the ALTLVDS_TX or _RX but the wizard works well for the ALTGX, ALTBUF and other functions.

The Java application launcher error "could not open the java virtual machine" happens consistantly when I start the MegaWizard Plug-in manager and attempt to create a new component or edit a previously created using the ALTLVDS_TX or _RX megafunctions.

The Megawizard Plug-in works fine with many other Megafunctions including the ALTGX, ALTDQ ALTIOBUF to name a few.

The error is the same if the Megawizard plug-in is run from the Quartus software or from the Windows Start->programs->... menu

The error happens after clicking Next on page 2a of the MegaWizard Plug-in manager - it does not matter which type of output file is selected

After reading about the problem - which seems commonplace - I experimented by killing all unnecessary programs, anti-virus, services to insure maximum RAM is available for the Java launcher and no software conflicts - all without success

People are suggesting to add a -xmx<max_memory_size> to the command startup but other than in the Java console (which I tried) I do not know how to do that

On the Linux version running on a VM CentOs 5.6 the Megawizard also fails consistently for the ALTLVDS_TX or _RX but the wizard works well for the ALTGX, ALTBUF and some other functions. Here the MegaWizard starts the launcher but crashes, the error messages are more detailed:

[david@localhost ~]$ cd /opt/altera/quartus/bin/

[david@localhost bin]$ ./qmegawiz

Error:Error in CNX file format.

Error messages are listed in file

/home/david/altera/txOutputSerializer.cnxerr.

Can't create the custom megafunction variation file(s)

The ....cnxerr file:

No valid wizard signature (generation mode ) found

Has anyone encountered these problems? Any solutions?

Altera SR says: Quartus 32 bit versions have known problems particulaarly with the megawizard - solution: use the 64 bit versions

    Well the 64bit Linux version of Qv11.0 sp1 won't do it either and give the same error on the DDIO_xxx component.

    I am having the same problem generating a DDO through the wizard. I get an error file with this message:

    line 0: "device_family_stratix ii 01115926r8064412233s"

    no valid wizard signature (generation mode ) found

    Funny thing is, I'm using an Arria GXII.

    if you use a 64bit OS, use the 64 bit version of quartus. 64 bit Linux, type "quartus --64bit"

    64bit works. However, word has always been that 64 bit performance is not as good as 32bit, and only necessary with devices that need the larger RAM support.

    So, the work around is to generate the part in the 64bit IDE wizard, then build out of 32bit. Not exactly direct, but it works. Wish Altera would fix the 32 bit version.
