hi all, i have doubt in floorplanning the design in ASIC 1. when we go for flattened floorplanning or hierarchical floorplanning.what is the adv and disadv of each of this? 2. what is the adv and disadv of hardmacro and softmacro? 3. A design is floorplanned with hard macro,my question is whether chip area is more for floorplaning with hard macro then the floorplanning with standard cells only(without using hard macros). which is best? what is the adv and disadv of each of this? thanks in advance, jothi murugan.B
