A Petri Net based Model for Heterogeneous Embedded Systems
نویسندگان
چکیده
Design of embedded systems must be based on formal representations so that the synthesis process can be carried out systematically. We present PRES, a Petri net based model suited to embedded systems. It can represent several levels of detail using the feature of hierarchical decomposition. This model also includes an explicit notion of time. In PRES tokens hold information and transitions, when fired, perform transformation of data. Concurrency and sequential behavior might be naturally represented in PRES. The representation is formally defined and an example explains different concepts and the semantics of the model.

In this paper the real time operation of an automatic teller machine (ATM) is analyzed using aTimed Petri Net (TPN) model. In the modeling, the probability of arrivals, the speed andattentiveness of customers (clients) are taken to account. Different parameters are based onthe statistical data. The model is simulated for 24 hours. The diagrams of number ofsucceeded customers, failed references ...
متن کاملA rule-based evaluation of ladder logic diagram and timed petri nets for programmable logic controllers
This paper describes an evaluation through a case study by measuring a rule-based approach, which proposed for ladder logic diagrams and Petri nets. In the beginning, programmable logic controllers were widely designed by ladder logic diagrams. When complexity and functionality of manufacturing systems increases, developing their software is becoming more difficult. Thus, Petri nets as a high l...
متن کاملA Formal Petri Net Based Model for Antivirus Update Agent System
In this paper, a formal model for antivirus update agent system is presented based on mobile agent technology and predicate/transition Petri nets. The mobile agent system contains two mobile agents called DCA and UNA. It sends out agents to update antivirus on client computers in a network. Each agent takes on a specified responsibility. First, DCA roams through the network and check the last d...
متن کاملVerification of Heterogeneous Electronic Systems using Model Checking
The ever increasing complexity of heterogeneous electronic systems consisting of hardware and software components poses a challenge in verifying their correctness. The complexity of this kind of systems is such, that traditional validation methods, like simulation and testing, are not enough to verify their correctness. In consequence, new verification methods that overcome the limitations of t...
