Formal Verification - Properties, Equivalence, and Signoff

Course promise

This is the execution-focused Formal Verification course for silicon and verification teams. It teaches how to reason from proof symptoms to model mechanisms, then close decisions with reproducible evidence, ownership, and release-safe residual-risk handling.

• Translate property-level status into requirement-level confidence decisions.

• Diagnose failures across modeling, assumptions, proof engines, and implementation root causes.

• Connect formal closure outputs to CI, signoff, and waiver governance.

• Use one framework: requirement -> mechanism -> artifact -> owner -> decision.
