Floorplanning in Physical Design
Floorplanning is a critical stage in the physical design of integrated circuits (ICs). It involves the strategic placement of various components on a chip to ensure optimal performance, minimal area, and efficient power distribution. A well-executed floorplan lays the foundation for a successful IC design, impacting factors such as routing complexity, signal integrity, and overall power consumption. Essential Inputs for Floorplanning Before diving into floorplanning, it's essential to gather and prepare the necessary inputs: Netlist (.v): The list of circuit elements and their connections. Technology File (techlef): Contains information about the technology node and design rules. Timing Library Files (.lib): Provides timing information for different cells. Physical Library (.lef): Details the physical dimensions and characteristics of cells. Synopsys Design Constraints (.sdc): Specifies the design constraints. Tlu+: Lookup tables for resistance and capacitance values used i...
