The script is available on a link shared on other thread, so anyone can use it.
I will try to fix Metal1 density problems, I assume that `metal1-dummy` layers should be away from `contact`, `m1`, `via1`. Is there any more layer that the density cells can't touch?

<@U03B029DKU5> Regarding the fill, it appears that the metal1 and metal2 fills are not functioning correctly, and there is no COMP fill in this script, correct?

After reviewing the messages related to the fill and your scripts,  the poly fill is too close to the blocks (a lot of parasitics) and dense. This density will not comply with DRC rules, and the patterns need to be adjusted. Typically, metal fills are done using a hash (#) pattern.

The GF180 Open-Source PDK provides <https://gf180mcu-pdk.readthedocs.io/en/latest/physical_verification/design_manual/drm_13.html|guidelines on Dummy Fill Rules and Guideline>s. I believe that creating a script from scratch to comply with all these rules might be quite challenging.
