Is it possible to create a Veristand System Def File using Matlab?

[jarboem]

Hello, I have a VeriStand project that uses a Simulink model.  I have multiple Simulink models for different vehicle architectures.  The dabases for the vehicle architectures are often updated.  When the databases are updated I must update the Veristand System Definition file by Importing Frames, adding User Channels, changing X-NET databaes exc.  What I have attempted to do is use the information from my databases and my Simulink mapping file to create a Veristand System Def.  

I started by opening an already made SDF in notepad++.  I wrote a Matlab script that will copy all unchanged info, write to a new xml file, also update all necessary information.  When I tried to load my created file (saved as .nivssdf, and even gives me the Veristand icon on my desktop) I receive the following error:  Is it possible to change the VeriStand SDF by changing the information in notepad++ or Matlab?  Any and all feedback is very much appreciated!

Hello, your error looks like an XML syntax error. Your generated text must be wrong (maybe missing quotes or so..?)

Best regards.

I would recommend invoking the VeriStand System Definition API from Matlab(TM) directly using Matlab's .NET integration. This will be much more reliable than trying to write the XML file directly. This is the supported API for scripting system definition files. I am not an expert in this area, but I believe Matlab has really good support for calling .NET code.
