Methods to estimate die area
Method 1:
Each cell has got its area according to a specific library. Go through all your cells and multiply each cell in its corresponding area from your vendor's library. Then you can take some density factor - usually for a standard design you should have around 80% density after placement. So from this data you can estimate your
required die area.
Method 2:
One more way of doing it is, Load the design in the implementation tool, try to change the floorplan ( x & y coordinates ) in a such a way that the Starting utilization will be around 50% -to- 60%. Again, it depends on the netlist quality & netlist completion status (like Netlist is 75%, 80% & 90% completed).

is there any specific formula for die arear estimation?
