The timing metrics for gf12/ca53 show a severe regression:\n- cts__timing__setup__ws degraded from -248.0 to -900.0 (a ~260% degradation).\n- cts__timing__setup__tns degraded from -2080.0 to -6700.0 (a ~220% degradation).\n\nRelaxing the regression limits to accommodate such a massive timing regression is highly discouraged as it masks potential tool or flow bugs introduced by the OpenROAD submodule update. The root cause of this timing regression in the tool should be investigated and resolved instead of updating the baseline rules to accept these degraded values.

The antenna diode count for sky130hd/microwatt during global routing has increased significantly by ~36% (from 2520 to 3427). This substantial increase in diode insertion can lead to routing congestion and area overhead. This indicates a potential regression or change in the antenna avoidance/diode insertion behavior of the updated OpenROAD tool that should be investigated.
