Honored ContributorI am using DSP Builder 9.1+Quartus 9.1 +MATLAB2008a.
currently I am facing a problem while analyzing the model: Matlab Error Java Exception Occurred: The character ' ' is an invalid XML character at ...... at ...... Caused by:java.io.IOException:The character ' ' is an invalid XML character Can anybody help me ? thank you very much!
Honored ContributorI 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).Honored ContributorThank 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.Honored ContributorDid 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?
Honored ContributorI have done both of them,and they both faced the problem.
It's really CONFUSING.Honored Contributorhi,
there is another problem: Is there anything wrong with the path of the softwares related? In my computer, the path of QUARTUS is D:\ProgamFiles\altera\..., and the path of matlab is D:\ProgamFiles\matlab\.... Is there anything wrong? Thank you very much!Honored ContributorThe 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.Honored Contributorthere is no space between Program and Files.
Now I have reinstalled Quartus into C:\atera\...,but there is still the problem I metioned in# 1.
