What is the difference between a logic design and physical design in VLSI?

 

In VLSI (Very Large Scale Integration), logic design and physical design are two distinct phases of the design process.

Logic Design: Involves creating a digital circuit using a hardware description language (HDL) such as VHDL/Verilog  creates a high-level representation of the circuit, specifying its functionality and behavior

Physical Design: Involves transforming the logical representation of the circuit into a physical layout that can be fabricated as a silicon chip Includes tasks such as floor planning, placement, routing, and layout verification aims to optimize the layout for performance, power consumption, and manufacturability.

In summary, logic design is concerned with creating a logical representation of the circuit, while physical design is concerned with creating a physical implementation of that circuit that can be fabricated.
