A top-level floorplan shows which blocks communicate with I/Os. Green lines represent I/O connections. Nets connecting two Pblocks are bundled, and the bundles change size and color based on the number of shared nets.

Data Path Top-Level Floorplan

This view shows data flow between top-level blocks. Each block communicates only with two neighbors. Green lines indicate well-placed I/Os that communicate with a single block.

Control Path Floorplan

This view shows a design where all 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 reach all other loads.
