Generate production quality code from state diagrams created with Enterprise Architect

SinelaboreRT generates readable and maintainable code from hierarchical UML state machines. With its unique features and the C code generator the tool covers well the requirements of embedded real-time and low power application developers. With its C++, Python and Java backend it is also a perfect tool for developers of server or desktop applications.

Key Features:

• Automated robustness checks before code generation
• No run-time environment needed
• Can be used with any CPU and with or without OS/RTOS
• Code generation especially for embedded real-time and high availability systems.
• Fits well in different system designs (foreground/background, RTOS-based …)
• No gap between design and code
• Support for automatic test-case generation
• Simulation in interactive or batch mode.
• Optionally generating trace code
• Generated code creates no trouble when using static code checkers

The following example shows how the code generator works by means of a simple microwave oven.

Requirements:

• Cooking time can be adjusted from 0s and 60s.
• Cooking starts if the cooking time is > 0s and the door is closed.
• If the door is opened during cooking the microwave generator is switched off. The cooking time stops.
• Cooking continuous if the cooking time is not over and the door is closed again
• Cooking stops if the cooking time is over or the time is adjusted to zero.
• Cooking time and power can be changed at any time.

The sate machine below shows a possible solution.

To generate for example C code just export your model to XMI and call the code generator as follows:

java -jar codegen.jar -p EA -t "Model:Class Model:first_example_step3" -o oven first_example_step3.xml

After checking the model against a set of well-formedness rules (e.g. no double state names) the complete state machine code is generated.

Done!

Look into the generated files: oven.c oven.h oven_ext.h

In the examples folder you will find the complete code ready to be tested and expanded by you.

The code-generator supports a subset of the design elements provided by Enterprise Architect. The supported elements are:

• Hierarchical states
• (Signal-)Events with event name, guard and action – Initial and final pseudo-states
• History states (deep, flat)
• Choices
• Junctions
• Constraints
• Sub-machine states on various levels
• Entry and exit pseudo-states
• Regions on various levels

• How sinelabore supports model based testing of state diagrams
• How to interactively simulate your state diagram and generating trace code
• Read section “Drawing State-Charts with Enterprise Architect” in the manual
• How easy it is to add attributes and operations to the stateful class like shown below. Operations are mapped to C-functions. Attributes to members of the instance data of the state machine. This allows to add entry/exit code functions or other helper functions. Even the body code can be easily added with EA if you want. Presently attributes and operations are only generated in the C-backend.
