| − | Tasking Event-B is the extension of Event-B for defining concurrent systems sharing data, for details see the [[Tasking Event-B Overview]] page. For more information contact Andy Edmunds - University of Southampton - mailto:ae2@ecs.soton.ac.uk
| + | [[User:Son]] at '''ETH Zurich''' is in charge of the plug-in. |
| − | === Sensing and Actuating for Tasking Event-B ===
| + | {{TOCright}} |
| − | Sensing and actuating events, and an Environ Machine have been added to allow simulation of the environment and implementation using memory mapped IO.
| |
| | | | |
| − | A new case study has been produced that makes use of these new features, details available at http://wiki.event-b.org/index.php/Event-B_Examples
| + | == Introduction == |
| | + | Event-B Qualitative Probability plug-in provides supports for reasoning about termination with probability 1 (almost-certain termination). |
| | | | |
| − | The example/tutorial projects, and also and a Bundled Windows version, are available in the [http://deploy-eprints.ecs.soton.ac.uk/304/ Deploy E-Prints archive].
| |
| | | | |
| − | The projects are also available from the [https://codegenerationd.svn.sourceforge.net/svnroot/codegenerationd/Examples/HeatingController_Tutorial_v0.1.4/ Examples SVN site]. | + | == Installing and Updating == |
| | + | The plug-in is available through the main Rodin Update Site under '''Modelling Extension''' category. |
| | | | |
| − | Sources for Tasking Event-B and Code Generators are available from a branch on the [https://rodin-b-sharp.svn.sourceforge.net/svnroot/rodin-b-sharp/branches/CodeGeneration/0.1.4 Rodin SVN site].
| + | == News == |
| | + | * 23.11.2011: Version 0.2.1 released for Rodin 2.3.* |
| | | | |
| − | === The Code Generation Demonstrator for Rodin 2.1.x === | + | == Technical References == |
| | | | |
| − | Released 24 January 2011.
| + | == Usage == |
| − | | |
| − | The Rodin 2.1.x compatible code generation demonstrator plug-ins have been released into the Rodin Sourceforge repository at:
| |
| − | | |
| − | https://rodin-b-sharp.svn.sourceforge.net/svnroot/rodin-b-sharp/trunk/CodeGeneration
| |
| − | | |
| − | The update-site is available through the Rodin update site in the ''Utilities'' category.
| |
| − | | |
| − | The code generation tutorial examples are available for download at:
| |
| − | | |
| − | https://sourceforge.net/projects/codegenerationd/files/DemoFiles/
| |
| − | | |
| − | The code generation plug-in relies on the Epsilon tool suite. Install Epsilon manually, since the automatic install utility does not seem to work for this feature. We currently use the Epsilon interim update site available at:
| |
| − | | |
| − | http://download.eclipse.org/modeling/gmt/epsilon/interim/
| |
| − | | |
| − | Select 'the Epsilon Core (Incubation)' component, this is the only component that is required for Tasking Event-B.
| |
| − | | |
| − | == Code Generation Status == | |
| − | === Latest Developments ===
| |
| − | * Demonstrator plug-in feature version 0.1.0
| |
| − | ** for Rodin 2.1.x version is available.
| |
| − | | |
| − | * The Code Generation feature consists of,
| |
| − | ** a tasking Development Generator.
| |
| − | ** a tasking Development Editor (Based on an EMF Tree Editor).
| |
| − | ** a translator, from Tasking Development to Common Language Model (IL1).
| |
| − | ** a translator, from the Tasking Development to Event-B model of the implementation.
| |
| − | ** a pretty-printer for the Tasking Development.
| |
| − | ** a pretty-printer for Common Language Model, which generates Ada Source Code.
| |
| − | | |
| − | * A tutorial is available [[Code Generation Tutorial]]
| |
| − | ** Step 1 - Create the tasking development.
| |
| − | ** Step 2 - Add annotations.
| |
| − | ** Step 3 - Invoke translators.
| |
| − | | |
| − | === Ongoing Work ===
| |
| − | | |
| − | * Full Rodin Integration
| |
| − | * Sensed Variables
| |
| − | * Branching in Shared Machines
| |
| − | | |
| − | === Future Work ===
| |
| − | * Support for Interrupts.
| |
| − | * Richer DataTypes.
| |
| − | * Accommodation of duplicate event names in tasking developments.
| |
| − | | |
| − | == Metamodels ==
| |
| − | * In the plug-in we define several meta-models:
| |
| − | ** CompositeControl: for the control flow (algorithmic) constructs such as branch, loop and sequence etc. These constructs may be used in the specification of either sequential or concurrent systems.
| |
| − | ** Tasking Meta-model: defines the tasking model where we attach tasking specific details, such as task priority, task type. The tasking structures provide the ability to define single tasking or multi-tasking (concurrent) systems. We make use of the composite control plug-in to specify the flow of control.
| |
| − | ** Common Language (IL1) Meta-model: defines an abstraction of common programming language constructs for use in translations to implementations.
| |
| − | | |
| − | == Translation Rules ==
| |
| − | * Tasking to IL1/Event-B translation rules [[http://wiki.event-b.org/images/Translation.pdf]]

| |
| − | === The Code Generation Demonstrator for Rodin 1.3.x ===
| |
| − | | |
| − | | |
| − | First release: 30 November 2010.
| |
| − | | |
| − | available from:
| |
| − | | |
| − | https://sourceforge.net/projects/codegenerationd/files/
| |
| − | | |
| − | The zip file contains a windows XP bundle, and a Windows V7 bundle. Alternatively, if you wish to build using an update-site, this is also included in the zip file, along with some notes on installation. However, note that the demonstrator tool is only compatible with Rodin 1.3.
| |
| − | | |
| − | A simple shared buffer example is provided. This will form the basis of a tutorial (which is work in progress). The WindowsBundles directory contains a Rodin 1.3.1 platform with the Code Generation plug-ins, together with a patch plug-in. The patch plug-in is required to correct an inconsistency in the org.eventb.emf.persistence plug-in. For the bundles, simply extract the appropriate zip file into a directory and run the rodin.exe. The plug-ins are pre-installed - the only configuration necessary may be to switch workspace to ''<installPath>\rodin1.3bWin7\workspace''. When using the update-site the example projects, and the project forming the basis of a simple tutorial, are provided in the accompanying zip file. These should be imported manually.
| |
| − | | |
| − | Mac users - no bundled version available at present, but use the update site in the 'advanced' folder.

| − | '''A step-by-step [[Code Generation Tutorial]] is available'''

| − | ==== About the Initial Release ====
| |
| − | The Code Generation (CG) Feature in the initial release is a demonstration tool; a proof of concept, rather than a prototype. The tool has no static checker and, therefore, there will be a heavy reliance on docs and dialogue to facilitate exploration of the tools and concepts.
| |
| − | | |
| − | ==== Source Code ====
| |
| − | | |
| − | The sources are available from,
| |
| − | | |
| − | https://codegenerationd.svn.sourceforge.net/svnroot/codegenerationd
| |
| − | | |
| − | Note - I used Eclipse 3.5 Galileo, and you will need to install (or have sources from) Epsilon's interim update site. There is also dependency on Camille v2.0.0
