After run the flow successfully, the DRC is not clean

[Elon-J]

When I try to increase the output load ability of my block, after passing the OpenRoad flow successfully, the DRC is not clean. What should I adjust? Attach my detail_route_issue_file:

detail_route_NON_CLK_GEN_sky130hd_base_2022-06-04_07-30.tar.gz

Attach my block repository: https://github.com/Elon-J/OpenROAD-flow-scripts/tree/master/flow/designs/sky130hd/NON_CLK_GEN Attach my report file, magic DRC report and layout DRC report:

6_report.log

sky130_drc.txt

6_final_drc.txt

@vijayank88 , Thank you very much! Let me check it!

[Elon-J]

@vijayank88 , By the way, actually I also check it using magic, there are also some DRC errors.

@Elon-J can you add the drc report and maybe zoomed in screenshots. That would be helpful to understand what is wrong.

@vijayank88 thanks! @Elon-J what is your fix for the buf_16?

[Elon-J]

@msaligane , I just try to increase the drive ability to generate a new CLK, and this problem has been fixed.
