PCB design, board making, patch and material one-stop hardware innovation platform, shorten the customer research and development cycle, convenient and worry-saving.
Comparison of several mainstream PCB software
Several mainstream PCB software, compare PCB Layout software
1.Protel, now push Altium Designer. Domestic low-end design mainstream, basically no use in foreign countries. Easy to learn, suitable for beginners, easy to use, occupy more system resources, higher demand for computer configuration. In the domestic use of Protel people still have considerable market, after all, small and medium-sized companies hardware circuit design or low-end mostly, but suggest you contact as soon as possible to learn other features better software. 2, pads
PADS software is also quite a lot of people, easy to use, easy to get started, personally feel better than Protel, I do not know how many times. Suitable for medium and low-end design, can be called the "king of the crown" in the low-end. Now, the most widely used EDA software in the market is suitable for the needs of most small and medium enterprises. It does not have simulation in itself. When doing high-speed boards, it must be combined with other special simulation tools.
3, Cadence Allegro
Actual industrial standards in the design of high speed panels.
The Cadence Allegro tool is absolutely top-notch, and a little familiar with the point, no longer want to use other tools, wiring super cool. Simulation is also very cattle, have their own simulation tools, Signal Integrity simulation, Power Integrity simulation can do. In the PCB high-speed board, firmly occupy the dominant position. You know, 60% of the world's computer motherboards, 40% of the mobile phone motherboard can be taken Allegro paintings ah!
4, Mentor WG
Slightly inferior to CADENCE, but also the top tools, aimed at high-end circuit design, but also have their own simulation tools. But in China, its support providers are relatively small, not as much as Cadence.
Others do not mention, use very few people.
If you rarely do high-speed panels, it is recommended to use pads bar, after all, relatively easy to learn. If you often do high-speed board, it is recommended or choose Cadence, one is to do high-speed domestic plate, Cadence more, second, because the popular, so learning, then communicate more people. A lot of big companies use it, and Protel and Cadence, Allegro's salary is different.
