title: Using .do files with ModelSim (10.3a)
body: <p><em>Here is the (brief) context for my question :</em> </p>
  
  <p>I am working in <strong>VHDL</strong> (with Microsemi's Design Suite, Libero) and I use <strong>ModelSim</strong> to simulate my work. To that extent, I use a classic VDHL TestBench and, to save time, a <strong>.do</strong> Macro File.
  This .do Macro file contains very basic commands such as "restart" or deleting/adding waves.</p>
  
  <p>Even if I'm not expecting much from such a file, it would be convenient for me to include in it more actions, that I have to perform by hand with the Graphical Interface like, something that I use quite a lot : combining signals into a custom bus. This action is very simple to do in Modelsim's graphical interface but I can't find anywhere how to perform this in a .do Macro File.</p>
  
  <p><em>So my question is :</em> </p>
  
  <p>Where can I find some good documentation regarding these ModelSim's .do Macro Files?
  Or am I missing the point about the use of these files? Is it relevant to use it in sich a way?</p>
  
  <p><em>I really hate to ask this kind of question here but, even if I was able to find some info here and there on various websites, I found nothing significant. I have been through quit a lot of ModelSim help documents or user guides but it almost always focused on the graphical interface.</em></p>
