Statecharts diagrams, through FSM form, are transformed into memory blocks using address register and ROM memory with reduced memory size obtained by the introduction of address modification. Good feature of the new algorithm is usage of dedicated Embedded Memory Blocks, whereas traditional logic cells can be used for …
The paper studies some variants of Statecharts step semantics in the framework of structural operational semantics. The chosen framework allows to study precongruence and congruence properties of behavioral preorders and equivalences and to compare, with respect to these properties, the different step semantics considered.
Statecharts are expressed in a graphical language to specify complex reactive systems. They are extension of state-transition diagrams to which notions of hierarchy and orthogonality have been added. Recently, they have been suggested to represent performance models and in this regard a software package has been developed.

The event-driven and sequential aspects of the specification are specified with STATECHARTS and continuous declarative processes expressed in SIGNAL can be associated with each state. The translation of STATECHARTS into SIGNAL defines a fully synchronous semantic of this formalism and allows to get unambiguously an executable …
We experimented Statecharts as a mediation tool between multiple experts and a knowledge engineer. After a short survey of knowledge elicitation for multiple experts, we present our method and critiques coming from our case study in …

For instance a partial specification of a production cell using data flow diagram,where synchronisation by events is mis~ing, requires an additional specification written, for Instance, in statecharts. -they may simply be independent: that is the case where they are unrelated .

3. FΔSL: delta-oriented programming for FSL. In this section we define, a textual language for delta-oriented product lines where variants are statecharts written in .This language, which formalizes the approach implemented in the HyVar toolchain, includes delta operations that can modify all elements of an statechart. Our presentation …
Statecharts employ notion of traditional state transition graph enhanced with concurrency, hierarchy and broadcast communication. One of undesirable problem which arises in specifying behaviour in this way is undeterministic situation, where at given instant of time, two or more transitions can move activity from one state. ... All rights are ...
Statecharts have been proposed recently as a visual formalism for the behavioral description of complex systems. They extend classical state diagrams in …

A statecharts behaves as task synchroniser at higher level of CIM hierarchy and is like logic controller that can be implemented in PLC's at the lower level of the hierarchy. We do not believe at the future of the only behaviour specufication except for discret event contrllers, Le case where the discret event nature of the system is …
Eg. BOTTLE BEING is a FILLED submode of BOTTLE LINE ON state. We model an operating mode as a Statecharts state. A state may include one or more concurrent sub-state_.charts, depending on the nature of the system. The WansiUons trom one state to anomer are defined. As a result we get a Statecharts diagram, including …
Statecharts are one of the most popular modeling formalisms that is used in a diversity of real world applications, such as cyber-physical systems, mobile computing, and bio-informatics. Following common step-wise refinement strategies, modelers often develop and evolve Statecharts models incrementally to satisfy requirements and changes.
In particular, it introduces the time delays associated with actions of the system and a solution to resolve struc- tural conflict. 2.7. An overview of statecharts Statecharts are an extension of finite state automata which provides hierarchical decomposition of states, explicit representation of concurrency and broadcast com- …
The state based specification language of VHDL/S is based on statecharts as introduced by D. Harel. Statecharts enhance conventional FSMs by notions of hierarchy (abstraction) and orthogonality (parallelism) to factor out common transition (sub-)structures and to avoid the prob- lem of state explosion in the graphical represen- tation.

StateCharts can be defined as a set of states, transitions, events, conditions, variables, and their interrelationships. The behavior described in SWC is directly related to the UI. States in SWC are depicted on the UI by means of containers for objects (graphic or executable …
Statecharts is a formal visual specification language for complex discrete-event entities. While the language is excellent for specifying real-time reactive systems and to build simulations and prototypes rapidly, statecharts suffers from the fact that the specifications are not verifiable.

Statecharts have already been discussed in view of describing hybrid systems control (Gueguen, 1992). In the present case, the Statechart formalism fits well for modelling a whole system's behaviour like the vehicle we are interested in. Speed control has been particularly emphasised, while other aspects, like the status of the electric ...
