How to generate *.sdf (system description file) from model ???

Hi all,

I remember that when I used matlab R2015a, when i generated code from model (ctrl B), the *.sdf file also generated.

But currently, I don't know how to generate *sdf file.

Please tell me if you know it.

Thank you so much,

I see hints it has to do with either dSpace or Polyspace
