Formal verification refers to mathematical techniques for specifying, designing, and verifying software and hardware systems. It involves proving or disproving the correctness of algorithms in a system with respect to a formal specification or property using formal methods of mathematics. Formal verification techniques include manual proofs, semi-automatic theorem proving, and automatic algorithms that take a model and property to determine if the model satisfies the property. Formal verification is commonly used for safety-critical systems like embedded systems to help ensure correctness. Tools like VC formal, VC LP, and Spyglass can be used to formally verify designs early in development without complex test benches or stimulus.

- 2. What is formal Methods • Formal methods refers to mathematical based techniques and tools for 1. Specification 2. Design 3. Verification of software and hardware systems.
- 3. What is formal verification • In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
- 4. Continue ………… • Formal verification is the act of proving or disproving the correctness of a system with respect to a certain formal specification or property.
- 5. Formal Verification Techniques Techniques Manual human tries to produce a proof of correctness semi-automatic theorem proving Automatic algorithm takes a model (program) and a property; decides whether the model satisfies the property
- 6. ApplicationDomainsof FormalVerification • Generally safety-critical systems: a system whose failure can cause death, injury, or big financial loses. • particularly embedded systems 1. often safety critical 2. reasonably small and thus amenable to formal verification
- 7. Tools for formal verification 1. VC formal 2. VC LP 3. Spyglass VC forma, VC LP and Spyglass combine to enable designers and verification engineers to quickly analyze and check RTL designs very early in the design flow, with no need for complex setup, test benches or stimulus.
