Physical Design (Netlist to GDSII)

Physical-Design

Physical design is based on a netlist which is the end result of the synthesis process. Synthesis converts the RTL design usually coded in VHDL or Verilog HDL to gate-level descriptions which the next set of tools can read/understand. This netlist contains information on the cells used, their interconnections, area used, and other details. Typical synthesis tools are:

1. Cadence RTL Compiler/Build Gates/Physically Knowledgeable Synthesis (PKS)

2. Synopsys Design Compiler

During the synthesis process, constraints are applied to ensure that the design meets the required functionality and speed (specifications). Only after the netlist is verified for functionality and timing it is sent for the physical design flow.

GDS (Graphic Data Stream) is a file that was developed by calma company in the year 1971 and the GDS II in the year 1978.

It is a binary file format that represents layout data in a hierarchical format.

  • Design Netlist (after synthesis)
  • Floorplanning
  • Partitioning
  • Placement
  • Clock-tree Synthesis (CTS)
  • Routing
  • Physical Verification
  • Layout Post Processing with Mask Data Generation

These steps are just the basics. There are detailed PD flows that are used depending on the Tools used Some of the tools/software used in the back-end design are

Many customers are initially concerned about the distance, but once they place the design order and had a chance to evaluate the designed product which either match or exceed expectations, they place many more repeated orders.
