Prerequisites:

  • Java Runtime Environment - A functional Java 8 (or newer) installation is required to run Workcraft.
    On Windows and OSX the easiest is to use Oracle's proprietary Java, which is available here. On Linux systems OpenJDK is usually simpler to install. It is not required to download the full JDK, the JRE is sufficient.
  • Third-party tools - Workcraft depends on a number of backend tools for model checking, synthesis and verification of the graph models.
    Workcraft distributions are bundled with Petrify, PUnf, MPSat and PComp tools. You still may need to install other third-party tools, such as Graphviz, minisat, chaf, abc.

Workcraft 3 series (Return of the Hazard)

This is the current version (last build from 21 September 2017) that supports Graphs, FSMs, Petri nets, DTDs, FSTs, STGs, CPOGs, Digital Circuits, Dataflow Structures, SONs, Policy nets and xMAS Circuits.

See changelog for the list of improvements since the previous releases (available at GitHub mirror).

Workcraft 2.2 branch (Attack of Scala)

This is an experimental version, written entirely in Scala based on the functional reactive programming paradigm. This version (last build from 29 April 2013) only supports Petri nets and FSMs, so if you need to work with other models please download the latest release of Workcraft 3 series instead.

  • This version only supports Petri nets and FSMs.
  • This version is not currently maintained.

Workcraft 2 series (Metastability Strikes Back)

This is the previous version of Workcraft (last build from 20 July 2014). It supports Directed graphs, Petri nets, STGs, CPOGs, Digital Circuits, Dataflow Structures, SONs, Policy nets and xMAS Circuits.

Workcraft 1 series (Classic)

This is the older version of the tool (last build from 1 April 2008), as described in the Petri Nets 2009 article. This version relies on a number of native libraries (DLLs/SOs), which are available for major platforms, but not all of them. The libraries for Windows and Linux OS's are bundled with the distribution.

  • This version requires an OpenGL-compliant graphics card with an appropriate set of drivers. OpenGL support is required for all platforms.
  • This version is no longer being developed.
