184.108.40.206.3. Top Congested Hierarchies and Nets Reports
If your design fails to route, you can use the Top Congested Hierarchies and Top Congested Nets reports to determine the most congested hierarchies and nets in the design. View these reports under Compilation Report > Fitter > Route Stage.
Use context menu commands to locate directly to the reported hierarchies and nets in the Text Editor, Assignment Editor, Pin Planner, Chip Planner, and other editors. Optimize your design in the reported areas to reduce the congestion and successfully route the design.
