Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Distributed modeling system of digital electronical devices on base Petri Nets A.A. VESELOV The article describes a software tool designed for creation of distributed simulation models digital devices of automatics and computer engineering based on Petri nets and experimental studies of their behavior. As the basic model has been used DPN-modification of Petri nets. The structure system and its functionality are described. A distinctive feature of this tool is that each component of the distributed model is implemented in the form of two interconnected units: function module and its external plenipotentiary representative (proxy). Organization of interaction between them is carried out through mutual exchange of messages. Keywords: Distributed discrete-events model, Petri nets, interface, remote interchange, distributed component, hierarchical reflection, functional module, proxy, input and output, visual forms of image.
