Utilization:Utilization defines the area occupied by standard cell, macros and blockages. In general 70 to 80% of utilization is fixed because more number of inverters and buffers will be added during the process of CTS (Clock Tree Synthesis) in order to maintain minimum skew.
Core utilization = (standard cell area+ macro cells area)/ total core area
A core utilization of 0.8 means that 80% of the area is available for placement of cells, whereas 20% is left free for routing.
