Esterel

Esterel is a specialized programming language designed for creating real-time, reactive systems—things like embedded controllers, automation, and safety-critical applications—that need to respond quickly and predictably to inputs. It allows developers to specify how a system behaves step-by-step, using clear, logical constructs to model the flow of signals over time. Esterel emphasizes deterministic execution, ensuring consistent responses in time-sensitive environments, making it ideal for designing reliable hardware and embedded software where precise timing and behavior are crucial.
