The VLSI (Very Large Scale Integration) design flow is a structured process that transforms a concept into a physical integrated circuit (IC) and includes stages like specification, design entry, verification, synthesis, physical layout, and manufacturing. It is broken down into front-end (behavioral and structural) and back-end (physical) stages, moving from a high-level behavioral description to the physical
layout required for fabrication.
Key stages of the VLSI design flow
Specification: Define the requirements, objectives, and features of the integrated circuit, which guides the entire design process.
Design Entry: Create a high-level representation of the circuit using a Hardware Description Language (HDL) like Verilog or VHDL, or through a schematic diagram.
Verification: Functionally simulate the design to ensure it meets the specified requirements and catch errors early.
Synthesis: Convert the high-level HDL code into a gate-level netlist, which is a list of logic gates and their interconnections.
Physical Design:
Floorplanning: Plan the overall layout and placement of major components on the chip.
Placement: Decide the exact position of each standard cell and other components.
Routing: Connect the components based on the netlist by drawing the physical wires.
Timing Analysis and Signoff: Verify that the design meets timing constraints, accounting for delays caused by wires and gates, before finalizing it for manufacturing.
Fabrication: Send the final design data to a semiconductor foundry for manufacturing.
Testing and Packaging: Test the manufactured chips to ensure they are functional and then package them for their intended use.
