With the rapid development of high-speed circuit design, PCB routing has evolved beyond simple interconnection tasks. Engineers must analyze various distributed parameters using transmission line theory. Distributed parameter circuits account for spatial variations in voltage and current. Modern PCBs, with their complexity and density, include advanced features like microvias, buried/blind vias, and embedded components (e.g., resistors, capacitors). These advancements require PCB designers to understand production processes deeply and adapt their designs to manufacturing constraints.
Achieving efficient automatic PCB wiring involves a blend of strategic planning, tool utilization, and manual refinement. By setting robust design rules, optimizing layout, and leveraging EDA tools effectively, engineers can create high-quality PCB designs that meet performance and manufacturability requirements. The iterative approach of routing, validating, and refining ensures that even the most complex designs achieve high routing rates and functionality.
