Abstract

The invention discloses an automatic component layout method based on a hierarchical structure. The method specifically comprises the steps that a PCB outer block diagram is imported into schematic diagram design software; drawing a sub-circuit module outer frame in schematic diagram design software; configuring a corresponding relation between an actual schematic diagram and a circuit sub-module outer frame in schematic diagram design software; generating a netlist in schematic diagram design software and adding layout information; importing a netlist into PCB layout design software and analyzing layout information; and classifying the components in the PCB layout design software and automatically placing the components in the associated layout area. In the schematic diagram design process, layout information is configured in advance and seamlessly transmitted to PCB layout design software, and the automatic layout function of the schematic diagram driven layout can be achieved. According to the automatic component layout method based on the hierarchical structure, automatic layout of components is achieved, and the design work of a PCB Layout link is greatly simplified.

Description

technical field [0001] The invention relates to the technical field of PCB layout design, in particular to an automatic component layout method based on a hierarchical structure. Background technique [0002] In the field of industrial software, EDA software, PCB layout design software, and schematic diagram design software, after the netlist file generated by the current schematic design software is imported into the PCB layout design software, users need to manually layout components. [0003] Existing PCB layout design software obtains component information by analyzing netlist files, and directly tiles all components in the canvas of the layout design software as a whole. Components bring trouble, especially when there are more than a hundred components, it is very difficult to find the components at one time. Contents of the invention [0004] The purpose of the present invention is to provide an automatic component layout method based on hierarchical structure. [...
