6.2 Component Automatic Instantiation

You need to type the first letters of the component(entity, configuration, component) name, then press Ctrl+Space three (3) times. You can recognize component instances by their icon, it looks like a chip with ports ready to be glued in.

You can customize what gets generated from menu Window > Preferences > DVT > VHDL > Editor > Content Assist in the Auto-instantiation section.
