**Content**

```text
In general, we trust KLayout. Passing magic DRC is not required for tapeout.

In some cases, such as for contacts, magic does not operate directly on the GDS layout (at least on gf180mcu), which can lead to false reports of DRC violations. That's why `ERROR_ON_MAGIC_DRC` is False in the LibreLane config.

However, the issue you mentioned came up with the latest LibreLane (and thus magic) update. The errors are M2.2a/M3.2a/M4.2a violations on the bondpad, which look like false positives to me.

I'll ask magic upstream about it. Thanks for reporting the issue!

You can reproduce it locally, open the layout in KLayout (`make librelane-klayout`), and then load the .lyrdb marker database from `67-magic-drc/reports/` of the run folder.
