The Netlist window displays the logic hierarchy of the synthesized design. You can expand and select any logic instance or net within the netlist.
As you select logic objects in other windows, the Netlist window expands automatically to display the selected logic objects, and the information about instances or nets displays in the Instance or Net Properties windows.
The Synthesized Design window displays a graphical representation of the RTL logic hierarchy. Each module is sized in relative proportion to the others, so you can determine the size and location of any selected module.
To open the Hierarchy window, in the Netlist window, right-click to bring up the context menu. Select Show Hierarchy, as shown in the following figure. Also, you can press F6 to open the Hierarchy window.
