Features

Tkenv is a graphical runtime interface for simulations. Tkenv supports interactive simulation execution, animation, inspection, tracing and debugging. In addition to model development and verification, Tkenv is also useful for presentation and educational purposes, since it allows the user to get a detailed picture of the state and history of the simulation at any point of its execution.

When used together with a C⁠+⁠+ source-level debugger, Tkenv can significantly speed up model development.

Its most important features are:

  • network visualization
  • message flow animation
  • various run modes: event-by-event, normal, fast, express
  • run until (event or simulation time)
  • simulation can be restarted
  • log of message flow
  • display of textual module logs
  • inspectors for viewing contents of objects and variables in the model
  • visualization of statistics (histograms, etc.) during simulation execution
  • eventlog recording for later analysis
  • snapshots (detailed report about the model: objects, variables, etc.)
