Improve Model-Based Systems Engineering with Requirements-In-the-Loop simulation

Prepare your students to become tomorrow's Systems Engineers, Systems Architects, Systems Designers and Test Engineers that will tackle embedded software complexity using an innovative and unique solution based on requirements-in-the-loop simulation.

CATIA STIMULUS enables the user to detect incorrect, missing and conflicting requirements, during the specification phase, before any design begins, and to generate tests vectors & objectives automatically.

A disruptive solution for the end-to-end validation of embedded systems

Teach your students how to make requirements right the first time, in a faster and better way!

Achieve early requirements validation

Share clear and validated requirements among engineers


of executable models, software, or hardware logs to ensure the system fulfills its requirements

Reduce costly iterations of the development process

An end-to-end requirement-based development and validation process for embedded systems

Duration 4 minutes 2


Industry is facing a rising level in complexity in embedded systems and hence writing complexity requirements for these systems is becoming increasingly difficult.

Teaching CATIA STIMULUS to your students provide them with the rights skills to tackle writing requirements for these complex embedded systems.

CATIA STIMULUS is the perfect bridge between Model-Based Systems Engineering (MBSE) courses and Control Engineering courses, especially as it integrates seamlessly with other de facto engineering tools such as CATIA MAGIC and Simulink.

Compared to traditional requirements engineering, CATIA STIMULUS is also fun and easy to learn thanks to the simulation aspects : students will be able to make requirements right the first time, in a faster an better way!

CATIA STIMULUS brings new, modern Requirement Engineering methods

Stimulus for Requirements

At specification phase, STIMULUS enables system architects to simulate requirements and to detect ambiguous, incorrect, missing, or conflicting requirements before the design begins, thus creating the high-quality specifications needed for the validation of safety-critical embedded systems.

Development teams spend less time redefining requirements, rewriting, and re-debugging code, resulting in fewer development iterations needed to achieve quality results.

Stimulus for Test: software validation

At validation phase, STIMULUS also enables test engineers to generate test vectors and test objectives automatically and to check that your embedded code complies with its specification.

Testing teams no longer write nor maintain test cases that are manually derived from the requirements. Instead, they reuse work done by system architects to build highly flexible test campaigns, allowing to adopt effective agile methods.
