How to properly estimate die size ?

[vak]

Hi,
How do designers arrive at the die size, if they know the package size. Say for example the package size is 14*14. ( It is a wire bond design )


Thanks

die size estimation

what is the number of IO pads ?
what is the least perimeter in which they can be arranged while meeting all DRC of wirebond ?
can you breakout to your ballmap with this arrangement ?

Is your core area larger than the area you get by arranging pads in square/rectangle above ? ( std cell area + analog blocks + routing etc...)

any specific requirement abt pad placement from floorplan of core ?

you need to explore all these questions to get to die size...
