10.4. Modern Floorplanning Considerations
Increasing design complexity and new circuit properties and requirements have reshaped the modern floorplanning problem. The new considerations and challenges make the problem much more difficult. In this section, we will discuss such crucial considerations. Specifically, we will focus on (1) soft modules, (2) fixed-outline constraints, and (3) large-scale floorplanning, and then highlight other important issues for modern floorplanning.
10.4.1. Soft modules
Unlike hard modules with fixed heights and widths, soft modules can change their heights and widths while keeping the same module area. The aspect ratio bounds are given as inputs for each module. There are many techniques for the adjustment of ...
