Hi, when i tred to do the hierarchical chip design example in docs (https://openlane.readthedocs.io/en/latest/tutorials/digital_guide.html), i realized that reg_file doesn't include other macros in it as expected in the documents. I guess it is because the lef file doesn't produce properly, is there a known bug or is it because my installation is broken? Here i attached the lef file with expected and original results.

yes, it is indeed generated incorrectly. Fill a bug at github with issue reproducibles
