The Congestion field toggles the -congestion Tcl switch ON and OFF.

Select the Minimum congestion level option to specify the minimum congestion to show router congestion in the design. The default minimum congestion level is 5 if not specified. The value must be between 3 and 8.

Equivalent Tcl option: -min_congestion_level <args>

Note: The congestion report is not generated/displayed if there are no router congested regions greater than or equal to the threshold level (-min_congestion_level). In that case, re-run the command with a lower threshold (values between 3 and 8).
