Die Area calculation

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).


  1. is there any specific formula for die arear estimation?

  2. Digital Workplace Software

    The digital workplace is a central working environment that employees can access from anywhere and at any time – whether they’re on the train, in their home office or at the beach. All data is stored in one location and can be accessed quickly and easily. Your employees are freer to determine when and how they work and therefore more efficient.
