What are YAKINDU Statechart Tools?

YAKINDU Statechart Tools (YAKINDU SCT) is a modular toolkit for developing, simulating, and generating executable finite-state machines (FSM) or simply state machines. State machines are useful for the model-driven development of so-called event-discrete systems, i.e. systems that are always in exactly one state of a finite number of states. State machines are particularly well-suited for embedded systems, but they are in no way restricted to them.

With YAKINDU Statechart Tools you can easily develop and simulate state machines, as well as generating them as source code for your target software system. YAKINDU Statechart Tools is based on the open-source development platform Eclipse.

The Standard Edition of YAKINDU Statechart Tools provides the following features for dealing with state machines:

• Statechart diagram editor to graphically create and edit statecharts, the graphical representation of state machines
• Statechart simulator to simulate the behavior of statecharts
• Code generators for Java, C, C++, and TypeScript to transform statecharts into programming language source code
• Custom generator projects to easily create model-to-text transformations with Xtend or Java in order to create any code of your own choice
• Integrated validator to check for syntactical or semantical problems of the statechart model
• Testing framework to test your state machines with unit tests

The following graph shows these features and their relation to each other:

The Professional Edition of YAKINDU Statechart Tools makes additional features available:

• Deep integration with the C programming language to directly access C variables, types etc.
• Advanced simulation and debugging with breakpoints and snapshots

Who is using YAKINDU Statechart Tools?

Initially YAKINDU Statechart Tools have been designed for the embedded systems industry: automotive, system controls, vending machines etc. However, YAKINDU Statechart Tools are bringing the benefits of finite-state machines (FSM) and Harel statecharts to everyone who needs to design, simulate and develop behavior. People can use YAKINDU Statechart Tools to generate Java, C, C++, or TypeScript code.
