1. AD software analysis

　　The market positioning of AD (including PROTEL99) software is some simple boards, such as SCM, simple industrial boards, and some relatively simple boards. This software is widely used. It is relatively low end product design. Most of them are simple boards. The products of most companies using this software are relatively simple. Generally, there are two floors and four floors. In the Chinese market, mainland cities use more, while developed cities use less. Basically, it can be said that in developed cities, it is difficult to find a job with this software. However, this software has a high usage rate in mainland cities. In my opinion, the main reason why this software is so high in mainland cities is that it has been well promoted in schools, because every student majoring in electronics or electromechanical has taught or asked to learn this in schools. So for engineers who are still using this software, I can be sure that more than 80% of them are used in schools and continue to use it after leaving the society. So it can be said that if there is no market for Chinese college students, this software should be very rare in the Chinese market.

　　2. PADS software analysis

　　The predecessor of PADS is POWER PCB, which has few software interface menus and is easy to get started. I think this is also recognized by the market. In particular, the market share of consumer electronic products is very high. In the early days, it can be said that they were almost monopolistic in consumer products, such as VCD, DVD, MP3, MP4, U disk, LCD TV, tablet computers, tachographs, car electronics, navigation devices, digital set-top boxes, Android smart TV boxes, mobile phones and so on. Especially for mobile phone PCB design, PADS software almost has the monopoly advantage. In the whole consumer electronic products, almost PADS accounts for the majority. Especially the market share of the previous years is absolutely high. In recent years, the software Allegro has become more and more popular. The share of PADS has a downward trend. However, in developed coastal cities, PADS still occupies the mainstream market, especially in Shenzhen, where most companies still use PADS, followed by Allegro. PADS is easy to find a job in Shenzhen.

　　3. Allegro software analysis

　　The advantage of Cadence Allegro is that it is powerful, but the disadvantage is that it is not easy to learn and learn. Therefore, 10 years ago or 78 years ago, the market share of this software was relatively low. Generally, it was only used by large companies, especially those making computer motherboards. Because this software has powerful functions, drawing large boards has advantages. Such as computer motherboards, large industrial control boards, server motherboards, and other large boards, his efficiency and advantages are very obvious. Therefore, his market is mainly on computer motherboards, large industrial control boards, server motherboards, and other large boards, as well as some tablet computers and mobile phone boards. Used with large companies. In the long run, Allegro has a great market prospect.
