Describe the bug

I am trying to make a circuit with ORFS but it is not DRC clean and they are many metal stubs.

I also tried to run the example for gcd with ihp-sg13g2 pdk. After the flow is completed successfully, final gds file has many wire stubs (Metal2,etc.) which are smaller than the minimum metal area (0.144um^2). Changing minimum metal area in sg13g2_tech.lef didn't fix the problem.

Expected Behavior

The final design should be DRC clean, no metal stubs smaller than 0.144um^2

Environment

output from /OpenROAD-flow-script/env.sh:

OPENROAD: /OpenROAD-flow-scripts/tools/OpenROAD

To Reproduce

1. clone the repo: https://github.com/The-OpenROAD-Project/OpenROAD-flow-scripts.git
2. run docker: docker run --rm -it -u $(id -u ${USER}):$(id -g ${USER}) -v $(pwd)/flow:/OpenROAD-flow-scripts/flow openroad/flow-ubuntu22.04-builder
3. uncomment gcd example in /flow/Makefile
4. make
5. check 6_final.gds file
