How to resolve this error?

I was setting location assignment for a logic cell and register, however, QII reported below error. Can anyone help me about this? My object device is EP4CGX15BF14C8. 

  Error (170065): Cannot split carry or cascade chain crossing 128 logic cells and starting on logic cell "CalibTDC1ch:inst3|tdc1ch_won:inst1|DelayLine128Top:u_DelayLine128Top|lpm_add_sub128bit:lpm_add_sub128bit_inst|lpm_add_sub:LPM_ADD_SUB_component|add_sub_0fk:auto_generated|pipeline_dffe[1]~128" into legal LABs

What is the location assignment exactly? Seems like resource restricted in the lab.
