Model Driven Development with Rhapsody

Model Driven Development with Rhapsody

• By Will Fritz

2
What is Model Driven Development?

• A method for producing software quickly,
  efficiently, and with as little cost as possible.
• Based around generating code directly from UML or
  other modeling languages.

3
Why use Model Driven Development?

• MDD allows for easier building and maintenance of
  complex state machines than direct work with
  code.
• Many embedded systems have too many states to
  keep straight easily through standard development
  methods

4
Why use MDD (cont.)

• With quality MDD tools, systems can be maintained
  wholly through their state diagrams and other
  models.

5
Advantages of MDD

• There are many advantages to using model driven
  development.
• By using models, software engineers and other
  stakeholders are able to argue conceptually about
  a problem without worrying about syntax or other
  platform specific issues.4

6
Advantages of MDD (cont.)

• The added ease of communication can lead to fast
  design times.

7
System independence

• System can be designed with very little
  information about final platform.
• MDD emphasizes building system independent
  models, then applying model transformations to
  make it fit the target system.
• This leads to better portability for the system.

8
Rhapsody

• Rhapsody is a MDD tool from Telelogic.
• It currently supports final code generation into
  Ada, C, C, and Java.
• It also supports 8, 16, 32, and 64 bit systems.

9
Rhapsody (cont.)

• Rhapsody can run simulations of the designed
  system.
• It can also run debugging on the target hardware.
• Lastly it includes support for built in
  requirements and model based testing.

10
Standards

• CORBA Common Object Request Broker Architecture
• D0-178B
• UML
• SysML
• DoDAF Department of Defense Architecture
  Framework
• AUTOSAR soon

11
Rhapsody Animator

• Rhapsody has a debugging tool called the
  Animator. It shows the current state of the
  simulation within the diagrams.

Target Debugging with Tornado

• When used for target debugging along with the
  Tornado IDE Rhapsody is able to show the status
  of the system in diagrams via the animator while
  target debugging.

Trane Example

• Used to design software for new high-efficiency
  water chiller
• Project went from blackboard to testing in three
  months
• Manager of SE Pat Wilson marked that as very fast
  for that type of project
