Papyrus-RT - UML-RT modelling and code generation environment

Papyrus-RT provides an implementation of the UML-RT modeling language together with editors, code generator for C++ and a supporting runtime system.

For more details, see the Overview section.

Some highlights

Graphical structure editor

Graphical behavior editor

The structure editor allows the user to edit capsule structure in a convenient way. It is possible to create and arrange capsule references and ports and to create bindings and layer connections.

The behavior editor allows the user to describe capsule behavior by means of a hierarchical finite state machine. It is possible to create and arrange states, choice points, junction points and transitions using the state machine editor.

Code generator

C++ runtime services support

A code generator will translate the UML-RT model into C++ code. This code generator will translate all structural (e.g., capsules, protocols, and classes) and behavioral (i.e., state machines) elements into C++ code, based on their properties, stereotypes, stereotype properties (including those from a profile with properties specific to C++), and runtime services elements. For the generation of the behavioral C++ code from the state machines, the code generator will first translate the behavior provided by each capsule's (or passive class') state machine into an intermediate model that will then be translated to optimized code. Based on user-provided thread allocation information, the code generator will also allocate capsules, or groups of capsules, to threads.

The C++ Runtime Services Library provides support for the execution of the C++ code generated from a UML-RT model. Capsule lifecycle functions (incarnate, destroy, import, deport), message delivery and timing services are provided by the services library and are used by both the generated code as well as the user specifed action code which is part of the capsule behaviour. The runtime system code is distributed in source form as an installable Eclipse feature. The code generator produces both standard makefiles as well as CMakeList files to build the generated code.
