In the field of special‐shaped panel design, TP (touch panel) design engineers need to manually complete the wiring routing work between the driven IC port and the TP pad port. Due to the routing channel is not regular, the equal line width method is usually adopted. Complete the routing in the channel in advance, and then adjust the routing line width to reduce the resistance discrepancy manually. As the resistance difference between the shortest and longest wire is relatively large, it is very extremely complicated for engineers to manually modify the line width to reach equal resistance for all the routing wires. At the same time, because the routing channel is often limited to a certain area, when adjusting one wire, the other wires will be affected. In order to achieve the purpose of automatic routing, we designed a routing method that distributes the line width in a limited area automatically, plus a method of superimposing serpentine wiring in the specified area to achieve the overall wiring resistance balance. In the paper, we referred to the idea of channel routing, first split the routing channel, and then routed in the split channel, and then connected the same net wiring in the channel, and adjusted the split channel according to the requirements of resistance. In the process of adjusting the resistance, the strategy of the simulated annealing algorithm is deployed to search the optimum routing result.
