Abstract: To attack the problem of automatic generation of cable network schematic, this paper proposes placement and routing algorithms by using the methods of row-column placement and channel routing, which have been extensively used for automatic logic diagrams generation, and taking into account the properties of cable network. The placement algorithm consists of row positioning of position symbol and column positioning of point symbol. Then the routing algorithm is executed in the row channels between two position symbols and column channels between two adjacent point symbols. The algorithms have been successfully applied in the self-developed automatic cable network schematic generation system, which can produce normal and good-look cable network schematic with correct logic circuit functional information, and the connections of the devices are given. This system has been adopted by several aerospace institutes for designing the cable network of rockets and missiles, and the automation level is significantly improved.
