"Physical Design" The physical layout is the procedure of remodeling a circuit description into the physical layout, which describes the placement of cells and routes for the interconnections among them. ASIC Physical Design Flow : The main steps in the ASIC physical design flow are: Design Netlist (after synthesis) Floorplanning Partitioning Placement Clock-tree Synthesis (CTS) Routing Physical Verification GDS II Generation The physical layout is primarily based on a netlist that is the stop result of the Synthesis procedure. Synthesis converts the RTL layout normally coded in VHDL or Verilog HDL to gate-stage descriptions which the subsequent set of gear can study/understand. This netlist carries statistics at the cells used, their interconnections, the location used, and different information. Typical synthesis gear are Cadence RTL Compiler/Build Gates/Physically Knowledgeable Synthesis (PKS) Synopsys Design Compiler During the synthes...
