    I suspect you have a strange character in your design somewhere. This is being serialised to XML and causes this error.

    Try going through your design making sure that all names use just "normal" characters. If you find the block that is causing the failure, please cut down the design to just contain that and I'll see if I can reproduce the error (assuming you're unwilling to post your full design).

    Thank you for your reply.

    The model is just the "Amplitude Modulation Design Example" in ug_dsp_builder.pdf, and there was no strange character in my design, so I am really confused about this Error.

    Did you use the singen.mdl file that can be found in quartus\dsp_builder\DesignExamples\Tutorials\GettingStartedSinMdl or did you follow the tutorial steps to recreate it yourself?

    I have done both of them,and they both faced the problem.

    It's really CONFUSING.

    The other problem is what? That Quartus is installed into D:\ProgamFiles\altera ?

    Assuming there really is no space between Program and Files then I'm sure that's fine. I have known in the past that spaces in paths can cause problems. Those issues may have been fixed though.
