The Howdy Glossary

Averest is a specialized programming language designed to prioritize the development of reliable and high-assurance software, integrating formal verification principles directly into its structure. It allows developers to specify and verify correctness properties of their programs using mathematical concepts like sets, functions, relations, and algebraic data types. Developed initially by Esterel Technologies, now part of ANSYS Inc., Averest's technology is incorporated into the SCADE toolchain used in model-based systems engineering for safety-critical industries such as aerospace, automotive, and rail transportation.

The language stands out through its unique integration of formal verification principles that aid in specifying and verifying correctness properties using rigorous mathematical methods. This feature facilitates automatic generation of verification conditions, streamlining the validation process crucial for ensuring software reliability. Unlike some competitors focusing on high-integrity systems like SPARK or analysis tools like Frama-C and Coq, Averest's built-in functionalities cater explicitly to the needs of developers working in environments where reliability is critical. The seamless incorporation within the SCADE toolchain further enhances its utility in developing dependable software for safety-critical applications.

Averest holds significant competitive advantages due to its robust approach towards formal verification-centric programming languages. Its ability to automatically generate verification conditions boosts efficiency in rigorous software validation processes essential for sectors with stringent safety requirements. By focusing on providing reliable solutions specifically tailored for demanding fields like aerospace and automotive industries, Averest offers a distinct edge over other tools by combining practical use within these sectors with advanced mathematical validation techniques. These characteristics collectively make it a powerful asset for developers dedicated to creating highly dependable software systems where failure can have severe consequences.
