The invention discloses a layout and wiring method and device, equipment and a readable storage medium. According to the method and the device, for the functional module of which the data processing logic is matched with the star topology structure, the constraint modes with different constraint capabilities can be utilized to constrain each sub-module in the functional module to perform layout and wiring according to the star topology structure, so that each layout and wiring result is obtained; then, the layout wiring result meeting the preset index requirement is selected from all the layout wiring results to serve as the layout wiring scheme of the function module, layout wiring in the module can be simplified, the probability of occurrence of problems such as winding congestion, short circuit, time delay and function errors is reduced, line resources, chip power consumption and chip area are saved, and the production efficiency is improved. And a layout and wiring scheme meeting the preset index requirement can be selected, so that the performance, manufacturability and time sequence convergence effect of the chip can be improved. Correspondingly, the invention also provides a layout and wiring device, equipment and a readable storage medium, which also have the above technical effects.
