ID:19724 Fitter requires <number> LABs for <name> in locations from lower-left (<number>, <number>) to upper-right (<number>, <number>), but only <number> LABs are available exclusively for that region. Fitting has terminated due to high LAB utilization in that region.

CAUSE: Valid clustering cannot be found in a region. It could be a clock region, a Logic Lock region, or an intersection of both.

ACTION: Increase the size of any Logic Lock region or the clock region in the corresponding locations.
