hi , what is the command for avoiding buffering on a net ? like equivalent of set_dont_touch_network in openlane?Thanks

In which stage of flow you want skip buffering? like cts, global route etc.,

all stages . -- start to end

If the command exists in OR then you should be fine to use it otherwise you'll need to update the OR version

added inside run_placement proc , but doesnt seem to be recognized -- need to update openroad ??
