Hello, I got some antenna violations in openlane when trying to harden my design. However the top-level design show no antenna violation. Is it important to solve all these antenna violations at the block level?

Antenna Summary:
Source: /project/openlane/vco_adc_wrapper/runs/vco_adc_wrapper/reports/routing//44-antenna.rpt
Number of pins violated: 10
Number of nets violated: 10

Furthermore, are there any methods to show these violations in Klayout or Magic for debugging? Thanks.
