09/23/2022, 6:37 PMHi @Tim Edwards, I am running into an odd magic crash when trying to write lef. I have two cells that are essentially flipped versions of each other. The first one writes lef out ok, but the second one makes magic crash. I updated magic to the latest Magic 8.3 revision 318 and the issue persists.
Command used:
lef write -hideAbhinav Uppal

09/23/2022, 7:38 PMThe immediate error is that there is a label "vdda" at (407704, 23488) that is attached to nothing (space). The underlying error is that magic crashes when a label attached to space is found by the "lef write" routine. I'm fixing that, but you might be able to work around the problem immediately by dealing with the label.
