Organization of Parallel Computing Processes in Distributed Automation Systems of Circuit Design

Discusses methods to build distributed systems of the automated designing on the basis of by diakoptical approach to the decomposition of the simulated circuit. The article deals with the method of describing systems using generalized signal graphs, which display the system of equations written in generalized cause-and-effect form. This description, in addition to a visual representation of the structure of links between subcircuits, eliminates the problem of choosing the sequence of numbering of internal variables of subcircuits and variables of communication nodes. The decomposition of the system on the basis of the diacoptic approach allows to implement an effective computational process based on the parallel organization of calculations, when the formation and processing of equations for individual subcircuits is performed on different nodes of the distributed network. This achieves significant savings in the required amount of RAM and significantly reduces the time required to solve the problem of modeling large circuits, which can significantly improve the efficiency of distributed automation system circuit design.
Keywords: computer-aided design, diacoptics, system modeling, generalized signal graphs, distributed systems, Internet technologies
