Esterel Technologies is a supplier of model-based design, validation, and code generation tools for safety-critical software and hardware applications. Esterel’s tools create formal specifications that produce control designs code in software and/or hardware.


Esterel Technologies, a wholly owned subsidiary of Ansys, Inc., has offices in Élancourt, France, and Mountain View, California. Esterel also has direct sales offices in Ottobrunn, Germany, Bracknell, United Kingdom, and Shanghai, P.R. China. Distributors in Japan, China, South Korea, Israel, and India complement the Esterel direct sales offices.


The Esterel Technologies' SCADE Product Family includes: SCADE System, SCADE Suite, SCADE Display, and SCADE LifeCycle. SCADE Suite was acquired from Telelogic in 2001. [3]

In September 2006, Esterel Technologies acquired the IMAGE product from Thales and Diehl Aerospace. [4] It is now proposed as SCADE Display, [5] a display framework targeted for Real-time applications, for prototyping, display design, simulation, verification and validation, DO-178B certified code generation (up to level A), and integration with other applications.

In February 2007, Esterel Technologies announced a partnership with Wind River Systems to integrate SCADE in VxWorks 653 Real Time Operating System. [6]


Created in 2000, Esterel Technologies is a spin-off from the French company Simulog (itself bought by Astek in 2003). Simulog was itself a spin-off from INRIA, and many of the initial founders came from the INRIA laboratory. [7] These include Gerard Berry, father of the Esterel language, which gave its name to the company. Its first product, Esterel Studio, was meant to bring synchronous programming language benefits to the industry (initially telecommunications and then EDA Electronic design automation). In 2003, a Lustre-based (one of the other synchronous programming language) tool-set named SCADE (Safety Critical Application Development Environment) was bought by Esterel Technologies, and the two academics communities behind these languages proposed a way to merge them. [8] The result has been productized as SCADE Suite 6 and its subsequent versions.

In 2006, the tool developed by THALES to design the A380 cockpit, named IMAGE, was transferred to Esterel Technologies, and re-branded SCADE Display.

In 2009, Esterel Studio was acquired by Synfora. [9]

In 2012, it was announced that ANSYS had signed a definitive agreement to purchase Esterel for approximately €42 million. [10]

Esterel is a synchronous programming language for the development of complex reactive systems. The imperative programming style of Esterel allows the simple expression of parallelism and preemption. As a consequence, it is well suited for control-dominated model designs.

Ansys American technology company

Ansys, Inc. is an American company based in Canonsburg, Pennsylvania. It develops and markets multiphysics engineering simulation software for product design, testing and operation and offers its products and services to customers worldwide. Ansys was founded in 1970 by John Swanson. Swanson sold his interest in the company to venture capitalists in 1993. Ansys went public on NASDAQ in 1996. In the 2000s, Ansys made numerous acquisitions of other engineering design companies, acquiring additional technology for fluid dynamics, electronics design, and other physics analysis. Ansys became a component of the NASDAQ-100 index on December 23, 2019.

Lustre is a formally defined, declarative, and synchronous dataflow programming language for programming reactive systems. It began as a research project in the early 1980s. A formal presentation of the language can be found in the 1991 Proceedings of the IEEE. In 1993 it progressed to practical, industrial use in a commercial product as the core language of the industrial environment SCADE, developed by Esterel Technologies. It is now used for critical control software in aircraft, helicopters, and nuclear power plants.

Femap is an engineering analysis program sold by Siemens PLM Software that is used to build finite element models of complex engineering problems ("pre-processing") and view solution results ("post-processing"). It runs on Microsoft Windows and provides CAD import, modeling and meshing tools to create a finite element model, as well as postprocessing functionality that allows mechanical engineers to interpret analysis results. The finite element method allows engineers to virtually model components, assemblies, or systems to determine behavior under a given set of boundary conditions, and is typically used in the design process to reduce costly prototyping and testing, evaluate differing designs and materials, and for structural optimization to reduce weight.

NESSUS is a general-purpose, probabilistic analysis program that simulates variations and uncertainties in loads, geometry, material behavior and other user-defined inputs to compute probability of failure and probabilistic sensitivity measures of engineered systems. Because NESSUS uses highly efficient and accurate probabilistic analysis methods, probabilistic solutions can be obtained even for extremely large and complex models. The system performance can be hierarchically decomposed into multiple smaller models and/or analytical equations. Once the probabilistic response is quantified, the results can be used to support risk-informed decisions regarding reliability for safety critical and one-of-a-kind systems, and to maintain a level of quality while reducing manufacturing costs for larger quantity products.

Rational Synergy is a software tool that provides software configuration management (SCM) capabilities for all artifacts related to software development including source code, documents and images as well as the final built software executable and libraries. Rational Synergy also provides the repository for the change management tool known as Rational Change. Together these two tools form an integrated configuration management and change management environment that is used in software development organizations that need controlled SCM processes and an understanding of what is in a build of their software.
