Hello everyone,

I am designing a complex PCB containing multiple communication interfaces and high-speed digital circuits, facing electromagnetic compatibility (EMC) challenges. I hope to make this PCB resistant to external electromagnetic interference while not interfering with other devices. I'm particularly interested in:

How to lay out and route cables to minimize electromagnetic interference (EMI)?
What are some effective grounding and shielding techniques in PCB design?
How to select and use bypass and decoupling capacitors to improve the EMC performance of the circuit?
Are there specific codes or standards that I should follow in my design to ensure EMC requirements are met?
