6. Verification and Validation of Chip Designs
Verification ensures that chip designs are correctly implemented, while validation confirms that the design meets user requirements. Various techniques such as simulation, formal verification, and prototyping are utilized to identify issues early in the design process, ultimately enhancing reliability and reducing time-to-market. Effective verification and validation strategies harness coverage analysis and automation to improve quality.

What we have learnt
- Verification ensures the design is correctly implemented; validation ensures it meets end-user requirements.
- Use simulation, formal methods, and prototyping to detect bugs early and reduce risk.
- Coverage analysis and automation increase verification quality and speed.
- Effective V&V improves reliability, correctness, and time-to-market for chip designs.
Key Concepts
- -- Verification
- The process that confirms that the design meets the specifications, answering the question 'Did we build the design right?'
- -- Validation
- The process that confirms that the design meets the user’s needs, answering the question 'Did we build the right design?'
- -- Design Under Test (DUT)
- The hardware component or block being verified.
- -- Testbench
- The simulation environment used to test the Design Under Test (DUT).
- -- Static Verification
- A technique that analyzes code without executing it, including practices like linting and formal checks.
- -- Dynamic Verification
- A method that tests behavior during simulation or emulation.
- -- Functional Coverage
- A metric that checks if all required behaviors of the design were tested.
- -- FPGA Prototyping
- A method of validating real-world functionality of designs before silicon fabrication.
