What is the role of floorplanning in VLSI design?

Floorplanning is a critical step in the physical design of VLSI circuits, involving the arrangement of functional blocks on the silicon die. It aims to optimize the layout for performance, power, and area by minimizing interconnect lengths, reducing congestion, and ensuring efficient placement of power and signal routing. Effective floorplanning can significantly impact the overall performance and manufacturability of the chip.
