Heron Build Status GitHub Version Try with Docker

Running on Radiotherapy.tesl

Heron [1, 2, 5] is a solver for the Tagged Events Specification Language (TESL) [3], a declarative language for specifying synchronization of discrete events for simulation. This prototype provides:

  1. Definition of TESL specifications for causality and time scale between events.
  2. Simulation by sound and complete generation of execution traces.
  3. Scenario testing.

Getting started

Try me with Docker

The easiest way to start with Heron is to get Docker and then simply type

$ docker run -it nguyenvanhai/heron
# ./heron --use examples/basic/FirstExample.tesl

Binary distribution

You can also fetch the latest binary release for your operating system (Linux and macOS).
