Seamless workflow from design to deployment

A fully integrated design-to-code process aligns software design with hardware constraints and system requirements, ensuring robust and efficient embedded applications. IAR Visual State provides state-machine-based modeling, which is particularly suited for safety-critical environments like automotive, industrial automation, and medical devices.

Accelerating embedded development with model-based design

Model-based design simplifies embedded software development with graphical modeling, reducing complexity and improving efficiency. This structured approach ensures predictable execution, faster development, and is ideal for safety-critical and industrial applications.

Low-code development, a key part of model-based design, minimizes manual coding through automated code generation, enabling rapid prototyping and deployment. State-machine-driven development enhances consistency, eliminating translation errors and streamlining the transition from design to implementation.

Modern embedded development requires collaboration across engineers, domain experts, and software developers. Graphical state-machine modeling acts as a universal language, improving communication and maintaining consistency across teams.

IAR Visual State automates C, C++, C#, and Java code generation, eliminating hand-coding bottlenecks while supporting embedded and app development for desktop, mobile, and HMI applications. With architecture-agnostic compatibility across 8-, 16-, 32-, and 64-bit systems, it integrates with various RTOS/OS environments. Variant handling simplifies configuration, and hierarchical coding optimizes performance, making scaling projects easier.

Integrated debugging, compliance, and functional safety

Ensuring software reliability and compliance is critical as designs move from modeling to implementation. Real-time hardware debugging provides visibility into active states and transitions, reducing troubleshooting time. Automated MISRA C:2012-compliant code generation enhances integrity, while built-in validation detects deadlocks, unreachable states, and conflicting transitions early, minimizing deployment risks.

Aligned with IEC 61508 SIL3+ recommendations, IAR Visual State accelerates safety-critical development in automotive, industrial automation, and medical devices. By integrating model-based design, low-code development, automated code generation, and compliance enforcement, it ensures a seamless transition from concept to deployment.

FAQ

Can IAR Visual State integrate with existing development environments?

Yes, it seamlessly integrates with IAR Embedded Workbench and other toolchains, supporting a smooth design-to-code workflow for embedded applications.

Do I have to modify the generated code?

No. The code generated by IAR Visual State focuses on the control logic of a state machine system. The design is always the only explicit representation of the control logic. The model and the executing code should always stay synchronized. Modifying state machine code by hand carries the risk of introducing hard-to-find errors in the internal bookkeeping of states and conditions. 

How can automated code generation improve efficiency and reduce engineering overhead?

By eliminating manual coding errors and reducing debugging time, automated code generation increases developer productivity and accelerates product delivery.

How can automated code generation reduce development errors while maintaining flexibility?

Automated code generation eliminates human errors, ensures consistency, and accelerates development by producing optimized and validated C/C++ code.

How does model-based development help teams scale embedded projects with consistent quality?

A standardized, automated process ensures consistency across projects, allowing teams to reuse proven components and reduce time spent on rework.
