How Formal Verification Works
At its core, formal verification involves the use of mathematical proofs to demonstrate that software behaves as intended. Here’s a closer look at the process:
Specification: The first step is to define a clear and precise specification of the software’s desired behavior. This specification acts as a blueprint against which the software is verified. It is usually expressed in formal languages such as temporal logic or first-order logic.
Modeling: The next step is to create a formal model of the software system. This model represents the system’s structure and behavior at a high level of abstraction. Various modeling techniques, including state machines and Petri nets, are used to capture the essential aspects of the system.
Verification: The formal verification tool then applies various algorithms and techniques to check if the model adheres to the specification. This process often involves model checking, theorem proving, and symbolic execution. If the software meets the specification, the tool issues a verification report confirming its correctness.
Feedback Loop: If discrepancies are found, the tool provides detailed information about the nature and location of the errors. This feedback is invaluable for developers, allowing them to refine the software and re-verify it until it meets the desired criteria.
