ASIC Design Flow Explained

The ASIC (Application Specific Integrated Circuit) design flow is the complete process used to design and manufacture a custom chip.
The major stages include:

1. Specification Defines the functionality and performance requirements of the chip.

2. RTL Design Engineers write RTL code using Verilog or SystemVerilog to describe circuit behavior.

3. Functional Verification Verification engineers test the RTL using SystemVerilog and UVM to ensure correctness.

4. Synthesis RTL code is converted into a gate-level netlist using synthesis tools.

5. Physical Design The chip layout is created using placement and routing techniques.

6. Timing Analysis Static Timing Analysis ensures the design meets performance requirements.

7. Tape-Out Final design data is sent to the semiconductor foundry for fabrication.
