WhICh software do you usually use to draw schematic diagrams and PCBs?

Hardware engineers are inseparable from schematIC design and PCBLayout. In order to design efficient PCBs, everyone must have a design software that is easy to use. This paper summarizes several commonly used PCB design software.

1、Protel/DXP/Altium Desginer

The reason for putting these software together is that they belong to the same company. These softwares are popular in China, easy to learn and user-friendly, and have gained many fans. Since its development, the software has formed a complete all-round electronic design system, including circuit schematic drawing, mixed signal SIMulation of analog and digital circuits, multi-layer Printed Circuit Board Design (including automatic routing of printed circuit boards), programmable logic device design, chart generation, spreadsheet generation, macro operation support and other functions, and has a Client/Server architecture.

2、CADence allegro

Cadence Allegro is the actual industrial standard for high-speed signal design. 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. The absolute hegemony in the production of high-speed circuit boards. According to statistics, 60% of computer motherboards and 40% of mobile phone motherboards are painted by Cadence, which shows how high its MARKet share is.

3、PADS

PADS software is the circuit schematic diagram and PCB design tool software of MentorGraphics. At present, this software is one of the circuit design software mainly used by domestic engineers and technicians engaged in circuit design, and is the most commonly used tool software for high-end PCB design users. As the mainstream PCB design platform in the industry, PADS has been widely used in the most active industrial fields, such as communication, semiconductor, consumer electronics, medical electronics, etc., due to its powerful interactive layout and routing function and easy to learn and use. PADS Layout/Router supports a complete PCB design process, covering all functional requirements from schematic net list import, rule driven interactive layout and routing, DRC/DFT/DFM verification and analysis, to final production document (Gerber), assembly document and bill of materials (BOM) output, so as to ensure that PCB engineers can efficiently complete design tasks.

4、Mentor WG

This software is rarely heard of, and I have never used it before. It is mainly aimed at high-end circuit design, and also has its own simulation tool. However, there are relatively few domestic supporters.
