This paper discusses the basic similarities and differences between analog and digital wiring in terms of bypass capacitors, power supply, ground wire design, voltage error and electromagnetic interference (EMI) caused by PCB wiring.

In the field of digital designers and digital circuit board design experts in the continuous increase, which reflects the development trend of the industry. Although the importance of digital design has brought significant development of electronic products, but still exist, and there will always be a part of the circuit design and simulation or reality environment interface. There are some similarities between analog and digital routing strategies, but the simple circuit design is not the best solution because of the different routing strategies. This paper discusses the basic similarities and differences between analog and digital wiring in terms of bypass capacitors, power supply, ground wire design, voltage error and electromagnetic interference (EMI) caused by PCB wiring.
