SPARK Pro
You simply can’t write better code.
When software failure is unacceptable, ultra-high reliability can be attained at the same level of effort as traditional testing-based methods.
SPARK is a formally verifiable subset of Ada designed for high‑integrity, safety‑ and security‑critical software. It removes features that hinder static analysis and adds contracts (pre/postconditions, invariants) to specify behaviour precisely, enabling automated formal proof on source code. Key benefits include guaranteed absence of runtime errors and many memory faults, stronger functional correctness, and predictable behaviour across compilers. These proofs can reduce unit testing effort and lifecycle defects, making SPARK attractive where failure is unacceptable.
