Layout and wiring control method, device and system based on wiring resources

The invention discloses a layout and wiring control method, device and system based on wiring resources. The method comprises the steps that a wiring device executes wiring operation according to a layout result generated by a layout device to obtain a wiring result; the wiring device judges whether wiring resources used by the wiring result meet predetermined wiring resource conditions or not; when it is judged that the wiring resources do not meet the wiring resource conditions, the wiring device generates layout guide information, and the layout guide information is used for being providedfor the layout device; when the layout guide information generated by the wiring device is obtained, the layout device optimizes the layout result according to the layout guide information to generatea new layout result, and the layout result generated by the layout device is used for being provided for the wiring device. Therefore, the layout wiring and the layout feedback operation can be circularly executed by taking t
