YAKINDU statechart models are executable. There are many use cases that require information about the execution itself. Examples are remote debugging of state machines, execution analysis, testing, co-simulation and others. This information may be provided live during the execution or it could be used post-mortem when the execution of the system already finished. In any case this information must be explicit and it must be possible to store it persistently and provide other tools access to this information.
The YAKINDU Execution Tracing (YET) infrastructure provides open formats, protocols, and APIs. It enables interoperability between state machines which execute on a target in the one side and YAKINDU (and other) tools on the other side.
