ID:186540 The fitter could not insert a delay cell to improve timing for the following DDIO output groups because there are no free logic cells in the same LAB

CAUSE: The LAB in which the DDIO group has been placed has no available logic cell that can be used as a delay cell. The fitter inserts a delay cell to improve timing for output DDIO groups.

ACTION: Remove the logic cell assignment for the LAB in which the DDIO group has been placed.
