Introduction
� For UML2Alloy, the instance of the destination model is an Alloy instance
which can be analyzed to identify the inconsistencies between various parts
of the design defined by the source model and to identify if the model is
under- or over-constrained.
� Alloy can produce a counter-example helping to reveal the source of
inconsistency.
� If a counter-example is found, it must be transferred to a UML objectdiagram
which is an instance of the class diagram in the design space that
represents a violation of a property of the system.
Introduction
� Snapshots from the UML2Alloy tool are shown.
The input to the tool is an
XMI file of the UML class
diagram created by
ArgoUML.
The output from the
tool in the form of
object diagrams.
