How can I display signals from an entity used as a component in my design on the wave diagram?
To view signals in a particular entity on your wave diagram, the steps are:
From the ModelSim vsim window menu, choose View | Structure
From the ModelSim vsim window menu, choose View | Signals
In the structure window, click on the entity
which contains the signals you want on your wave diagram.
This will cause the signals in that entity to
be displayed in the signals window.
From the signals
window menu, choose Add | Wave | Signals in Region.
The signals will be displayed on the wave diagram.
