WOKE: A novel workflow model editor

This paper presents a new work-in-progress tool, WOKE, to capture and present the workflow model in a novel way. A workflow model consists of linked steps to describe how actual work is done in a company and usually used for analysis and simulation. The complexity of modern System-on-Chip designs motivates applying such enterprise oriented models to the embedded design process domain as well. For example, UML Activity diagrams, YAWL, BPMN2.0, and flowchart descriptions have been used to capture the product design processes. They support very complex models, but that also leads to several different views that complicate the usability and comprehension. The key idea in WOKE is a very rapid creation and editing of the workflow by textual input, separate real-time graph visualization, comparison, and automatic summaries. User can select which details are visualized. Layout is automated and currently it uses a single column for all tasks and transitions. WOKE is implemented in C++/QT5 and is available as an open source tool. A proof-of-concept case study is shown for an FPGA-based SoC design.
