proof-carrying-code-generator

Proof-carrying code generation bundles executable code with formal proofs certifying safety and correctness properties. It produces verified software with accompanying proofs for memory safety, bounds checking, invariant preservation, and termination using Isabelle/HOL or Coq.

Proof-carrying code is executable software bundled with formal mathematical proofs certifying its safety properties. You need it for safety-critical systems, such as aircraft embedded components, where formal guarantees against bugs and vulnerabilities are absolutely required.

Yes, you can extract verified code into production-ready OCaml, Haskell, or SML. The extraction process takes the executable code proven correct in Coq or Isabelle/HOL and translates it into these target languages for deployment.

To prove functional correctness and termination for a binary search function, write a formal specification matching the intended behavior, then generate the implementation with an accompanying safety proof certifying bounds checking, invariant preservation, and termination properties.

Yes, formal verification with Isabelle/HOL supports proving invariant preservation and bounds checking. The generated code includes formal proofs certifying these specific safety properties alongside functional correctness and termination guarantees.

Limitations of using formal proofs include the need for precise mathematical specifications and significant verification overhead. This approach is specialized for safety-critical systems requiring guaranteed correctness, rather than general-purpose rapid application development.
