| 3 | # insert_layer.py: For the given install path, library name, and cellname, |
| 4 | # find the Magic layout of the cell, and add the specified layer geometry |
| 5 | # as given by a layer name and a string with four coordinate values. |
| 6 | # The layer is added to the layout in both the mag/ (full) and maglef/ |
| 7 | # (abstract) directories. Option "-maglef" or "-mag" will restrict the |
| 8 | # use to only the view indicated by the option. |

| 13 | # sky130_fd_io sky130_fd_sc_hd__a21bo_1 pwell "29 17 69 157" -mag |
