How can I display signals from a module instantiated in my design on the wave diagram?

To view signals in a particular module on your wave diagram, the steps are:

1. From the ModelSim vsim window menu, choose  View | Structure



2. From the ModelSim vsim window menu, choose  View | Signals



3. In the structure window, click on the module which contains the signals you want on your wave diagram.        
   This will cause the signals in that module to be displayed in the signals window.



4. From the signals window menu, choose  View | Wave | Signals in Region. 
   The signals will be displayed on the wave diagram.
