Integrated state-chart editor with auto-layout

Focus on modeling and not on moving states around to create a nice looking diagram! Syntax aware text fields offer a comfortable way to specify actions, guards etc. When the diagram passed the model checker it can be directly simulated. Connect the diagram to the real hardware to monitor the state machine in action.

There are better ways to model state machines than using spread sheets!

In the past different μC manufacturers have published application notes about the benefit of using state machines for the design of embedded software. An example is the application note SLAA402 from Texas Instruments (TI). It suggests to generate source code based on a spread sheet table. Nowadays several affordable UML modeling tools are available supporting the efficient design of state machines in a graphical way. SinelaboreRT generates production quality source code from state diagrams created with many different UML tools. Give it a try!

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.

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.

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
