Explore the hierarchy physically to understand the resource usage. To open the Hierarchy Window, select Tools > Show Hierarchy, or from the Netlist window, click F6.

As shown in the following figure, the Hierarchy Window displays a hierarchy map for the selected hierarchy. The hierarchy map displays the leaf cells as yellow blocks nested within rectangles corresponding to their parent hierarchy. Each level of the hierarchy is sized relative to the flat number of instances at that level compared to the total number of instances in the design.

The previous figure shows that cpuEngine, usbEngine0, and usbEngine1 have most of the logic in the design, and all use about the same number of resources.
