@Tim Edwards Excuse me, how can I add a layer for FIXED_BBOX on the layout, if it is possible?

property FIXED_BBOX

followed by four integer coordinates in magic's internal units, in quotes. If you have the cursor box placed where you want the bounding box to be, you can do:

property FIXED_BBOX "[box values]"

Thanks, is there a way to appear or show the FIXED_BBOX in the layout view, similar to the klayout?

If you select an instance of the cell or the cell itself, then the FIXED_BBOX appears as a white outline thinner than the usual cell bounding box. You can also edit the cell and type

property

to get a list of cell properties, or

property FIXED_BBOX

to get the abutment box coordinates specifically, or

cif see BOUND

to see the prBoundary layer that is output in GDS.
