The input–output place-transition (IOPT)-flow modeling framework was created to support the design of mixed embedded system controllers containing both reactive and data-driven parts, combining Petri net and dataflow elements. The reactive parts, whose evolution depends on external events, are modeled using Petri nets. Data manipulation operations that process input signals and events are expressed...
Petri nets have been widely used in the design of embedded controllers, namely in electronic hardware and computing platforms design, as well as within automation application areas. This paper presents updated characteristics of one class of Petri nets, named Input-Output Place-Transition Petri nets (IOPT nets), extended to support networked embedded controllers design and globally-asynchronous locally-synchronous...
This paper describes the IOPT-Tools cloud-based tool-chain, offering a complete set of Petri net tools with a Web interface supporting digital controllers development. The tools include an interactive graphical Petri net editor, a model-checking subsystem composed of a state-space generator, state-space visualization and a query system, and automatic code generation tools that produce software “C”...
