ACL2

ACL2 (A Computational Logic for Applicative Common Lisp) is a formal verification tool used by computer scientists to mathematically prove the correctness of software and hardware designs. It combines a programming language similar to Lisp with a powerful theorem prover, allowing users to specify systems, state properties, and verify that these properties always hold. By providing rigorous proofs, ACL2 helps ensure that complex systems behave as intended, reducing errors and increasing reliability, especially in safety-critical applications like aerospace, medical devices, and cybersecurity.
