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

Watch the code generator in action

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

microwave oven with requirements

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.

State machine of a simple microwave oven

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.

Supported State Machine Elements

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 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.

Classes have attributes and operations
