A state machine is a behavioral model. It consists of a finite number of states and is therefore also called a finite state machine (FSM). Based on the current state and a given input, the machine performs state transitions and generates outputs.

A single state chart may become very large and complex. embedded systems may consist of many state machines and other components. To understand the behavior of state machines within their execution context and their impact on the overall behavior of a system, the application of execution analysis and visualization are a proper way to gain this understanding.

impulse is a visualization and analysis workbench, which exactly provides tool support for such methods and enables engineers to understand and debug complex semiconductor and multi-core software systems. It also provides dedicated support for the analysis and of statecharts defined using the YAKINDU Statechart Tools. Using impulse, developers can relate signals and data from arbitrary sources to statechart execution and can visualize the data using a rich set of diagrams.

impulse YAKINDU Extension

YAKINDU Statechart Tools (itemis) offer an integrated modelling environment for the specification and development of reactive, event-driven systems based on the concept of state machines. You can develop and simulate state machines, generating them as source code for your target software system. YAKINDU Statechart Tools are based on the open-source development platform Eclipse.
The impulse components are fully integrated into the Eclipse framework (Windows, Linux and OSX/Mac) and can be combined with a growing number of new Eclipse technologies and enhancements (IoT, language IDEs, reports, CM, etc.). This enables a seamless integration with YAKINDU Statechart Tools.

More about the YAKINDU Statechart Tools More about the YAKINDU extension

The impulse YAKINDU extension integrates the Statechart Tools and enables signal-oriented simulation and visualization of YAKINDU state diagram models (https://www.toem.de/index.php/products/impulse-yakindu). The extension is helpful for creation (simulation with reference data) as well as for execution and tracing of the created state machine.
You may want to:

• Create and debug state diagram models
  Use the graphical editor to create state chart models and simultaneously visualize the simulation output with impulse;
• Inject reference patterns and check output
  Use the rich signal environment to create reference patterns, inject the patterns into the simulation and visualize/check the output;
• Trace state machines
  Capture online or offline traces from the executable (e.g., embedded device) and visualize them with the state chart and other plots.

impulse YAKINDU comes with three extension elements:

1. State chart production
   With state chart production, you can feed YAKINDU state chart models with online or simulation data (e.g., events) and display the results of the simulation (e.g., states and variables) in diagrams and charts;
2. State chart plot
   The state chart plot enables current states (online or offline data) to be displayed at the current cursor/online position.
3. YET Reader
   The YET Reader (YAKINDU Execution Tracing) allows to read state machine traces (online/offline) from running executables.

impulse YAKINDU is available with impulse 2.0.x.
