PCB Tech - Domestic popular PCB circuit design software

The PCB design software is based on the circuit schematic diagram to realize the functions required by the circuit design. The design of the circuit board mainly refers to the layout design, which needs to consider the overall layout of components and connections, including the optimized layout of internal electronic components; the optimized layout of metal connections and through holes; electromagnetic protection; heat dissipation and other factors. Excellent PCB design can achieve good circuit performance and heat dissipation performance, saving production costs. PCB design needs to be realized with the help of computer-aided design (EDA). Here are a few popular domestic PCB design software.

Introduction: The domestic popular PCB design software

The mainstream of domestic low-end design, simple and easy to learn, suitable for beginners. There is still a considerable market for domestic use of protel, after all, most of the low-end circuit designs of small companies.

PROTEL has now developed to the Altium Designer series, forming a complete all-round electronic design system, including circuit schematic drawing, analog circuit and digital circuit mixed signal simulation, multi-layer printed circuit board design (including printed circuit board automatic wiring), Programmable logic device design, chart generation, spreadsheet generation, support for macro operations and other functions, and has a Client/Server (client/server) architecture, and is also compatible with some other design software file formats, such as ORCAD, PSPICE, EXCEL And so on, the automatic wiring of its multilayer printed circuit board can achieve 100% layout rate of high-density PCB.

PADS (PowerPCB) is also used by many people, easy to use, suitable for low-end design, and has the title of "Uncrowned King" in low-end design. It is also the most widely used eda software on the market, which meets the requirements of most small and medium enterprises. PADS Layout provides interfaces with other PCB design software, CAM processing software, and mechanical design software to facilitate data conversion and transfer in different design environments.

Cadence allegro high-speed signal design is the de facto industry standard. PCB Layout is very powerful. Simulation is also very powerful, with its own simulation tools, which can realize signal integrity simulation and power integrity simulation. Absolute dominance in the production of high-speed circuit boards. According to statistics, 60% of computer motherboards and 40% of mobile phone motherboards are drawn by Cadence, which shows how high its market share is.

If you often make high-speed boards, it is recommended to choose Cadence. First, it has powerful functions and meets all the needs of design; second, because there are many high-speed Cadences in China, it is more popular, and there are many people who learn to communicate. Many large companies use Cadence, and the salary is also much higher, because the difficulty of designing high-speed circuit boards is relatively much greater than that of low-speed circuit boards.
