Flash type FPGA wiring method considering programming interference

The invention discloses a flash type FPGA wiring method considering programming interference, and relates to the technical field of programmable logic devices.The method includes the steps that when any destination point is searched in the process of conducting wiring on each to-be-wired network in a network list input by a user through a preset wiring algorithm, the destination point is searched from a source point of the to-be-wired network; fan-out nodes are selected according to wiring cost components obtained through calculation of the nodes based on a preset wiring algorithm and the programming cost of the flash switches corresponding to the nodes, searching is carried out in sequence till a target point is searched, and the programming cost of each flash switch represents programming interference borne by the flash switch in the FPGA programming process. According to the method, optimization is carried out on the basis of a conventional wiring method, programming interference brought by the programming
