What software do you need to learn for circuit development and design? Circuit design software refers to software for circuit diagram drawing, optimization, testing, and simulation. In China, the most developed and used circuit design software are as follows: protel, powerpcb, Allegro, orcad, cam350, etc. These circuit design software include functions such as electrical schematic…

When developing electronic products with processors, how to improve anti-interference ability and electromagnetic compatibility? This article summarizes some methods for everyone. Selecting a microcontroller with a low external clock frequency can effectively reduce noise and improve the system’s anti-interference ability. For square waves and sine waves of the same frequency, the high-frequency components in the…

When starting a hardware development project, the original driving force will come from many aspects, such as market needs, needs based on the entire system architecture, functional implementation needs of the application software department, needs to improve certain aspects of the system, etc. Therefore, as a hardware system designer, you must take the initiative to…

Many electronics enthusiasts like to do some electronic production by themselves. When making, they often spend a lot of time on the circuit board. Most of them use universal boards, but universal boards can only be built with wires, and cannot be routed according to the PCB design they have designed. The things they make…

There are many ways to solve the EMI problem. Modern EMI suppression methods include: using EMI suppression coatings, selecting appropriate EMI suppression components and EMI simulation design, etc. This article starts with the most basic PCB layout and discusses the role and design techniques of PCB layering and stacking in controlling EMI radiation. Power bus…

This article interprets the four basic characteristics of RF circuit from four aspects: RF interface, small desired signal, large interference signal, and interference from adjacent channels, and gives important factors that need special attention in the PCB design process. 1.RF interface of RF circuit simulation Conceptually, wireless transmitters and receivers can be divided into two…

According to the rule of thumb, four-layer boards are usually used in high-density and high-frequency situations, which are more than 20 DB better than two-layer boards in terms of EMC. Under the condition of a four-layer board, a complete ground plane and a complete power plane can often be used. Under this condition, it is…

Functional verification is becoming a bottleneck in IP verification and affects the entire design team. Design engineers seek ways to improve verification efficiency to achieve the best benefits for the entire chip design. Here, we provide 10 simple tips to significantly improve your IP verification efficiency. 1.Participate in verification plan review Well begun is half…

In today’s society, a large number of electronic products are widely used in our daily work and life, so their reliability needs to be guaranteed, and most electronic systems and equipment that use printed circuit boards must have reasonable design schematics and correct printed circuit boards to fundamentally improve their reliability. For example: assuming that…
