Integration to Theta

This folder contains plugins for the mapping of high-level Gamma (composite) models to a symbolic transition system formalism (xSTS). XSTS models can serve as input for Theta, a generic, modular and configurable model checking framework. Theta supports the formal verification of xSTS models based on reachability criteria. The plugins provide support for the seamless integration of Gamma and Theta, that is, the construction of queries, their evaluation using Theta, and the back-annotation of the verification results in addition to the automatic transformation of the Gamma models.

Furthermore, the plugins support the automatic generation of standalone Java statechart code from Gamma statecharts based on xSTS models.

Setup

  1. Set up an Eclipse with the core Gamma plugins.
  2. Set up Theta, more specifically the theta-xsts-cli tool by going into the theta-bin subfolder and executing Get-Theta.ps1 (Windows) or get-theta.sh (Linux). The script will download the required binary and libraries.
    • Alternatively, you can check out the instructions for other options (e.g., build from source). For Gamma, only the theta-xsts-cli.jar and the Z3 libraries are required.
  3. Put the downloaded libraries (dll/so files) in the theta-bin folder onto your PATH.
  4. Create an environment variable with the name of THETA_XSTS_CLI_PATH, which points to the downloaded theta-xsts-cli.jar binary.
  5. Set up the plugins in this folder:
    1. Import all Eclipse projects from the the xsts folder.
    2. Generate the Model plugins of the hu.bme.mit.gamma.statechart.lowlevel.model, hu.bme.mit.gamma.xsts.model and hu.bme.mit.gamma.lowlevel.xsts.transformation.traceability using the .genmodel file in the respective model folder. The generation of additional plugins (Edit, Editor, Tests) is not necessary.

Now you can use the framework in one of the following ways: you either run a runtime Eclipse and work in that or install the plugins into your host Eclipse.
