The timing metric 'globalroute__timing__setup__tns' shows a significant degradation of approximately 37% (from -206.0 to -282.0). While other timing metrics like 'cts__timing__setup__ws' and 'finish__timing__setup__ws' have improved, this large degradation in global routing TNS suggests potential routing congestion or optimization issues introduced by the OpenROAD update. It is recommended to analyze the global routing stage to identify the cause of this regression rather than simply relaxing the regression threshold.
