From Schematic Diagram to PCB: Closed-loop Control Method for EMC Full-Process Design of High-Speed Digital Circuits
High-speed digital circuits are evolving towards ultra-high speeds such as 56Gbps PAM4 and 112Gbps NRZ. Electromagnetic compatibility (EMC) issues have risen from an auxiliary design stage to a core factor determining the success or failure of a product. The traditional serial mode of "design - test - rectification" is difficult to meet the development requirements of high-end products such as AI servers and 800G optical modules due to its long cycle and high cost. This paper proposes a full-pro
