DEVSML Studio Simulation Trace Viewer

The auto-generated code in the coupled model’s main function creates two coordinators:

  1. TraceCoordinator
  2. Coordinator

By default, TraceCoordinator is used so that it generates a Simulation Trace file when the main function is executed.

After the execution is completed, a timestamped “Simulation Run (<model name>) <timestamp>” is created in the project workspace. Note: Ensure that IDE workspace is automatically refreshed by checking this box as in figure below.

The generated file is vieweable as a UML Sequence Diagram in the associated PlantUml plugin. The Sequence Diagram reflects the flattened version of the coupled model. The component name reflects the fully Qualified name.

Test Installation

  • Using Eclipse Git perspective, import Git repository:

Import Git repository

  • Import existing project as clone finishes

Import as Eclipse Project

  • Open the FdsSamples project in Plugin perspective and open entities.fds. Add Xtext nature if prompted

Import as Project

  • Open the PlantUml View if not open.

Open PlantUml Plugin

  • Open the atomics.fds for DEVS Statemachine visualization

PlantUml View


  • Open gpt.fds and gpCoupled/ and RunAs… Java Application. By default, a TraceCoordinator is used to run the simulation that generates a trace that is readily viewable as a UML Sequence diagram.
