Abstract: A device may analyze, by one or more processors, a model to identify a first set of model elements that are associated with a model element. The device may apply, by the one or more processors, one or more results from an analysis of the model to a first network unit to determine a complexity of the first network unit or a coupling of the first network unit to other model elements of the model. The device may generate, by the one or more processors, a second network unit, representing a second hierarchy of computation, from the first network unit based on the complexity or the coupling. The device may provide, by the one or more processors, the second network unit as a testing unit for testing the model, the second network unit comprising two or more model elements and one or more numeric expressions.

Abstract: A system and method extends model verification through the creation of composite test objectives. A composite objective includes two or more logically or temporally combined standard or basic test objectives. The basic test objectives selected to form a composite test may be automatically generated by the system or method, or they may be custom defined. A composite test objective represents a new coverage objective that extends model coverage analysis beyond the coverage that is available with the basic test objectives. The system and method also automatically generates one or more test cases for achieving the composite objective. The test cases include input data values for the model, and may cause the specified logical or temporal combination of basic test objectives to evaluate to true at least once during simulation of the model or according to the temporal combination.

Abstract: A method for providing writing requirements for a structured transition system employing state machines. The requirements employ a plurality of structuring mechanisms, namely, sub-state based structuring, abstraction based structuring and partial behavior structuring that uses event sequences. The sub-state based structuring has to do with the hierarchical requirements of the state machines, abstraction based structuring provides an abstraction of the state machines that reduces the number of states, and partial behavior structuring looks at certain states to predict how those states will affect other states.

Abstract: A method for developing a specification includes receiving a plurality of requirements that define the functionality of the specification, wherein the plurality of requirements are expressed using a formal model. The method further includes analyzing the plurality of requirements using algorithms and determining if the plurality of requirements satisfies a predetermined set of criteria. The method further includes generating a summary of the formal analysis and refining the requirements by incorporating corrected analysis results.
