MODELWORKS®

Modelworks® Overview:

Modelworks® is an automatic verification tool.  It verifies that a design in Simulink/Stateflow correctly encapsulates requirements expressed in Kapture®.  In order to ensure that the design is verifiable, a pre-check is undertaken to ensure that the design conforms to a design standard.  If there are errors, these are clearly highlighted so that a user can amend the design.  The check can be run against specific requirements or the entire set.  Should a check fail, Modelworks® highlights which requirements are not satisfied and identifies the specific part of the design that is related to the requirements.  A script can be run in the simulator so that a designer can understand the behaviour as designed and hence to diagnose the issue.  It might be that the requirement(s) need to be adjusted or that the design is wrong.

Modelworks® can be used in any form of software life cycle including traditional processes such as waterfall or V-model as well as in agile processes.  The requirements can be partially completed, for example as part of a sprint or an iteration, and the design developed to reflect the specific requirements.  It is likely that requirements will change as a result of better understanding of the system requirements.  Once the software requirements have been updated in Kapture® and the design altered to reflect these changes, Modelworks® automatically verifies that the design satisfies these changes.  This speeds up the design processes and ensures that the next development step, coding, is undertaken from a sound basis.  Modelworks® supports a formal methods based development process which consequently gives high assurance.   Use of Modelworks® is therefore extremely flexible and supports rapid, assured software development.
