- Direction: The direction of the congested routing resources (North, South, West, or East).
- Congestion Level: The maximum congestion level in CLB tiles.
- Congestion: Indicates the estimated routing resource utilization in the defined window. This value can be greater than 100%.
- Congestion Window: Indicates the bounding CLB tiles where the congestion for the identified Direction is present. The CLB coordinates correspond to the lower left and upper right corners of the window.
Tip: The Congestion Window column is only available in the text report. In the GUI report, you can select the congestion window, which highlights the congested area in the Device window.
- Cell Names: Indicates the parent instance that contains the hierarchical cells involved in the Congestion Window, up to the three largest contributors along with their contribution percentage.
