HCL RTist is a development environment for creating complex, event-driven and real-time applications. It is specifically designed to help software engineers with feature-rich tooling for design, analysis, building and deploying embedded, IoT and real-time applications.

After September 30, 2024, our real-time application development tool, HCL RTist V11.1 and V11.2 (PID=HCL18OP1179), will reach the End of Support. Customers running HCL RTist 11.1 or 11.2 are advised to upgrade to a newer product version, V11.3 or newer. The upgrade will be straightforward, and your old models should work the same way as in 11.1 and 11.2. From a migration point of view, the main difference is the supported compilers.
