Use the following metrics when the design is placed. These metrics do not require full routing to provide accurate results:

LUT Utilization per CLB
Color codes slices based on placed LUT utilization.
FF Utilization per CLB
Color codes slices based on placed FF utilization.
Vertical Routing Congestion per CLB
Color codes the fabric based on a best-case estimate of vertical routing usage.
Horizontal Routing Congestion per CLB
Color codes the fabric based on a best-case estimate of horizontal routing usage.
Interconnect Congestion Level
Color codes the Interconnect Congestion Level based on a worst-case estimate of routing usage across contiguous regions.
Note: This metric is for AMD UltraScale+™ and newer architectures.
