If I have a area report from DC,which tell the cell area and internect area. for example, total cell area is 150000 um2 and interconnect area is 2000000, how can I figure out my die size from this report? Can it be just cell area or cell area plus interconnect area and multiplied by a factor?please help me and thanks in advance
Die size is normally defined by the size and number of IO cells which are used and if you choose pad or core limited IO's. To get a proper result, and see if there is enough room to do the placement and routing, you will pretty much have to shove it into the place and route tool and see what results you get. I don't know of any easier way around that just by going from synthesis results.
The area from DC is only the number of the cell and connect with including into the chip, the area according as it shall have a big error.
If need the accurate area report, you must do the P&R.
