Printed circuit board (pcb) wiring automatic design method and system

A printed circuit board (PCB) wiring automatic design system, comprising:

• at least one processor;
• and
• at least one memory including an instruction,
• wherein the memory and the instruction cooperate with the processor to:
• receive PCB data including a net list and information on a plurality of terminals;
• update a cost of the wiring exploration region so that a cost of at least some of the wiring exploration region is increased based on a preset constraint condition;
• explore a shortest path for wiring the plurality of terminals according to the net list in the cost-updated wiring exploration region;
• and
• perform wiring of the plurality of terminals based on wiring probability according to the shortest path.

A printed circuit board (PCB) wiring automatic design method in a PCB wiring automatic design system cooperating with an artificial intelligence agent, the system including at least one processor and at least one memory including an instruction, and the PCB wiring automatic design method performed in cooperation with the instruction, the memory, and the processor, the PCB wiring automatic design method comprising:

• receiving PCB wiring target information in the agent through a conversation of a user via a user terminal as a medium;
• specifying grid cells corresponding to the shortest path that satisfies a preset constraint condition among a plurality of grid cells forming a wiring exploration region, based on the target information;
• performing a wiring design according to the PCB wiring target information based on calculated probability information, by using information on the grid cells corresponding to the shortest path;
• and
• providing, via the agent, a wiring result to the user terminal.
