# Elaenia: Automated Error Analysis of Numerical Software for High-Consequence Systems

This repository provides tools and techniques for automated

floating-point error analysis of C programs with the goal of making it

easier to specify and verify behavior of numerics-heavy C programs, with

a focus on embedded systems.

## Structure of this Repository

This project began with exploration into a Frama-C plug-in. We soon

realized that the ReFlow project provides better opportunities for

improvement rather than writing our own Frama-C plug-ins. This is now

maintained as a fork for [ReFlow](https://github.com/nasa/reflow).

- examples - example functions for analysis. They are ordered in

  increasing complexity as follows

    1. 01_straightline - No control flow, no transcendentals.

    2. 02_transcend    - No control flow, transcendentals (sin, cos, sqrt)

    3. 03_vectors      - No control flow, but operations on vectors

    4. 04_matrices     - Operations on matrices

    5. 05_kalman       - Various Kalman filter examples

- acsl - Proposed language extensions for the ANSI C Specification

  Language (ACLS) to better support compositional floating-point

  reasoning.

## About

This work is funded by Sandia National Laboratories' Laboratory

Directed Research & Development (LDRD) program, project 24-1299:

"Automated Error Analysis of Numerical Kernels for High-Consequence

Systems with Frama-C" and project 25-0103: "Automated Error Analysis of

Numerical Software for High-Consequence Systems."

Sandia National Laboratories is a multimission laboratory managed and

operated by National Technology and Engineering Solutions of Sandia,

LLC., a wholly owned subsidiary of Honeywell International, Inc., for

the U.S. Department of Energy’s National Nuclear Security Administration

under contract DE-NA-0003525.

The name Elaenia is taken from the name of an album by a band called

Floating Points. It is also a kind of bird.
