Six FAQ Analysis of Cadence Design
A perfect PCB:
The transmission rate of high-speed PCB design and cabling systems is steadily accelerating, and it also brings about some kind of anti-jamming vulnerability. This is because the higher the frequency of transmitting information, the higher the sensitivity of signals, and the lower and higher the power of their signals. The wiring system at this time is more susceptible to interference. Interference is ubiquitous. Cables and equipment can interfere with other components or be severely disturbed by other sources of interference, such as: computer screens, mobile phones, motors, radio transmission equipment, data transmission, and power cables. In addition, potential eavesdroppers, cybercriminals, and hackers continue to increase because of their enormous damage and loss to UTP cable information interception.
The reuse function provides design duplication for powerpcb (ie, a system that implements a modular design). For the successful use of the reuse function, we greatly improve our work efficiency; and we can call some successful designs and high-performance modules in the new design, thus improving the success rate of our new product pcb design.
To do high-speed PCB design, you must first understand the following basic concepts. This is the basis.
Each PCB is basically composed of an aperture hole layer, a DRILL layer, a circuit layer, a solder mask layer, and a character layer. In CAM350, each layer loaded is distinguished by a different color, so that we can easily operating.
EI: Electromagnetic interference, is widely found in various types of electrical and electronic equipment. Various types of electrical and electronic equipment emit electromagnetic waves more or less when they work. This kind of electromagnetic waves will interfere with the normal operation of the entire equipment. Due to inadequate consideration of electromagnetic compatibility in the design of electronic products, some electrical and electronic products have failed. Therefore, the author summarizes some points to pay attention to.
Six common shortcuts in PADS software
PCB routing is a key element of ESD protection. A reasonable PCB design can reduce the unnecessary costs of troubleshooting and rework. In the PCB design, due to the use of transient voltage suppressor (TVS) diodes to suppress direct charge injection due to ESD discharge, it is more important in the PCB design to overcome electromagnetic interference (EMI) electromagnetic field effects generated by the discharge current. This article will provide PCB design guidelines that can optimize ESD protection.

All of the examples in this article were developed using the multisim design environment, but the same concepts apply even with different eda tools.
Four principles as below:
People think that the earth can absorb all the charges, always maintain a stable, is the ultimate reference point. Although some boards are not connected to the earth, but the power plant is connected to the earth, the power of the board will eventually return to the power plant into the ground.
