The top-level floorplan shows which blocks communicate with I/Os (green lines). Nets connecting two Pblocks are bundled together. The bundles change size and color based on the number of shared nets. Two top-level floorplans are shown in the following figures.

The Data Path Top Level Floorplan shows how the data flows between the top-level blocks of the design. Each block communicates only with two neighbors. The green lines show well-placed I/Os that communicate with a single block.

Figure 1. Data Path Top Level Floorplan

The Control Path Floorplan displays a design in which all the blocks communicate with a central block. The largest connection is between the central block and the block in the bottom right. The central block must spread out around the design to communicate with all the other loads.
