@User I know you're black boxing the 
chip_io
cells, but when I try to extract devices anyways, I get 22.5K 
[ERROR]: There are illegal overlaps (e.g., routes over obstructions) in your design.
messages. Do you know what causes these messages.
a
The "feedback" file at 
runs/<tag>/logs/magic/magic_ext2spice.feedback.txt
should give you a list of locations where magic is seeing illegal overlaps.
if you're using the 
mag/
view of the pads or the GDS, this shouldn't happen because there is no sense of obstructions there; otherwise, it might be pointing at the pads and fillers around the IO ring being connected by abutment.

@Ahmed Ghazy Thanks for the hint. I'm viewing the layout (GDS) in klayout. The coordinates are scaled by 5, correct?
a
In microns, you should divide the coordinates by 2000. e.g., 
box 30753 928199 30801 929228
-> (15.376, 464.099) - (15.400, 464.614)
(Then you can use the "go-to-location"/CTRL+G thing in KLayout to visit those coordinates)

Thanks! That's what I needed to know. (I thought I tried that and it was the middle of the chip - empty in chip_io. I'll try again.)

@Mitch Bailey: Sorry, you need to divide by 200 not 2000...
