Completed/Ongoing Work

• Demonstration plug-in,
  • ready for deployment.
  • deployment/Integration Testing under way.
• The plug-in 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.
  • 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.

The Demonstration Plug-in Release

The demonstration plug-in is planned for release around November-end 2010, if all goes well. It must be emphasised that the Code Generation (CG) Feature is a demonstration tool; a proof of concept rather than a prototype. The tool has no static checker, and it is therefore to be expected that there will be a reliance on docs and dialogue to explore the features of the CG tools successfully. We will be working on this aspect in due course.

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.
  • 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 [[1]]
