System and method for similarity analysis of netlist topology

A similarity analysis system of a netlist topology, comprising:

• a printed circuit board (PCB) module database, wherein the PCB module database comprises a plurality of reference PCB modules;
• and
• a processing host, coupled to the PCB module database,
• wherein the processing host is configured to execute a similarity analysis assistant program and a layout user interface program,
• wherein the layout user interface program obtains netlist data, wherein the netlist data corresponds to a design of a PCB,
• the similarity analysis assistant program is configured to execute:
• generating netlist topology data according to the netlist data;
• analyzing the netlist data based on the netlist data and the reference PCB modules in the PCB module database through a learning algorithm to calculate hit rates individually between the netlist data and the reference PCB modules;
• and
• selecting at least one selected PCB module from the reference PCB modules according to the hit rates and the netlist topology data, and providing the at least one selected PCB module to a layout user interface,
• wherein the layout user interface presents the at least one selected PCB module on a user interface.
