Why can Chinese rockets go to Air space, but the chip, software? Because the United States controls the foundation of manufacturing, this scene can be called a bottom draw. If it is said that in terms of chip production, domestic companies can still cope with some scenarios, but China is far behind in terms of software. The key point is that the software is actually the upstream of production, which means that the United States has not only stuck China’s neck but also given the head.
In fact, industrial software is one of the biggest shortcomings in the entire Chinese industrial system. Many people think that China’s Internet ranks in the forefront of the world and they are all engaged in software. Where can industrial software be? This is really a cognitive error.
Although China’s Internet application is very powerful, China’s large-scale industrial software and chip design software are the weakest link.
Today I will tell you how industrial software is stuck in China’s neck. Let me talk about what industrial software is?
Workers who want to do a good job must first “use their tools”. These two sentences are essentially talking about the importance of tools. Industrial software is actually a tool in the industrial field.
Just like word and PPT, they are all tools.Industrial software can be roughly divided into three categories:
1. Help you design (CAD)
2. Help you simulate (CAE)
3. Help you manufacture (CAM) The English abbreviation is the beginning of CA, which means computer-aided.
The design software is called CAD, which is Computer Aided Design. To put it bluntly, it is drawing. For example, if you build a building or draw a part or chip, you need to draw drawings. The previous ones were all hand-painted. Now you have to let the computer help you draw, just drag the standard parts up and combine them.
The type of simulation is called CAE, which is Computer Aided Engineering. Chinese is computer-aided engineering. In terms of use, it is an experiment. For example, if you buy a clothes, do you have to try it? Then the current live broadcaster can also help You try. In fact, the principle of the simulation software is the same. It is to help you try to see if the design is appropriate and reasonable.
Manufacturing, that is called CAM, Computer Aided Manufacturing (computer-aided manufacturing), because production must be completed by machines. What about operating the machine? In fact, it is relying on CAM. For example, if you have a machine tool, you have to control the cutter head. How to move it and how to cut parts depends on CAM.
So why is the development of industrial software in China not good?
The first reason is: because it is difficult, in fact, industrial software looks like a software, but behind it is the crystallization of countless knowledge, is an absolute interdisciplinary field, it requires you, there are no shortcomings in various fields, only the computer professional participation is Absolutely nothing. First, he deals with “basic” disciplines.It can be said that industrial software programs cannot work without understanding mechanics. These animation simulations must be based on physical formulas, because industrial production is not a child’s play, it is not good-looking, it is necessary to be able to effectively guide the actual production.
In essence, the physical formula is written into the software, so that the software can quickly achieve the budget. And if the required physical formula does not exist, it is necessary to first derive the formula, which requires first studying the basic discipline of physics. After that, it naturally requires the computer’s underlying research capabilities. Some physical formulas are too complicated. Although the theory is correct, they cannot be solved. This is very similar to: you know that you can lose weight by eating less and exercising more, but you are The same can’t be done. At this time, computer scientists must come in to make this calculation possible.
Here is a very typical application. Computational fluid dynamics (Computational Fluid Dynamics), flow is a flowing object, such as water and air is very important. Calculating the impact of air on products is one of the important applications of CFD. This type of simulation must be done in the design of aircraft wings and car shapes. Today, it has actually involved more aspects, such as chip heat sinks.
In 1963, two Americans used IBM’s 7090 smart machine to solve the hydrodynamic equations for the first time by computer. After that, the computer continued to develop, making CFD more and more powerful. However, in the case of CFD, to be honest, China was killed by the United States. Last year, the US ban on Huawei had just begun, and Ansys was banned from sales in the United States. Ansys is the industry-leading industrial software. TSMC and MediaTek are all his customers. His business card-level product fluent in the CFD field is in the ban.
Now CFD analysis has completely replaced experiments to design industrial products. If the United States and the EU really implement the relevant policies seriously, China’s automobile and aircraft design must go back to the blowhole, and the industrial simulation software is controlled by the United States, Germany and France. Ansys first said, Siemens second, France’s Dassault third, the key is that the EU and the United States are inseparable from each other, the United States and Germany are the old guests under the long arm of the United States. Straightforward point tells you that the United States still controls the audience in the field of industrial software.
The second reason for China’s poor development is that there is not enough money. To be honest, nothing can be supported by love.
Now my domestic colleagues who work on industrial software have so little money (annual salary is around 100,000).There are market reasons for low wages, because the head effect of this industry is very obvious. In order not to be affected by their own R&D cycle, customers will only pay for the most advanced and reliable software. In the face of fair competition, domestic-made software is really better than high-end customers! After all, why should you bet on your future to give domestic warmth? Foreign goods are cheap and cheap. Isn’t it fragrant to use them directly? In addition, foreign industrial software has actually penetrated into the training of Chinese engineers. Most of the universities in China now, as long as you are an engineering student, you will immediately learn foreign industrial design software. For example, many people’s first 2D design software is AutoCAD, and his parent company, Autodesk, is American. The first 3D design software I learned is Solidworks, and his parent company is the third in the world just mentioned, Dassault in France. Do you think that controlling the university is not controlling the future engineers in China, but actually controlling Chinese talents from the source.
The third reason why China is not developing well: it may be policy. Supporting weak and small industries requires policy support. At least no money is given in the market, and policy can be given points. In fact, the money invested by the country is still not in place. For example, this time the EDA software on the Huawei’s neck. Two years ago, the US Department of Defense led the electronic revival plan. Pay attention to the meaning of the revival here. It is not that the United States is lagging in this field, but that the United States is not leading the way.
To expand its advantage in the United States, ERI plans to invest 1.5 billion US dollars, or about 10 billion yuan, in five years, and Cadence, some of the software giants mentioned above, has received US$24 million in funding. Note that this is just one of the following policies supported by the United States over the years. Looking at China, statistics show that during the 11th Five-Year Plan period, only a total of about 50 million yuan was invested in various policy investments in related fields, and no more than 200 million yuan during the 12th Five-Year Plan period. The gap is obvious at a glance. In other words, the intensity of a support policy in the United States is equal to fifty times the investment China has made in 15 years.
Another reason is that the location of industrial software is very strange. If you say that it belongs to software, then it belongs to industrial application according to the classification of China, and it should be under the control of the Ministry of Industry and Information Technology. But the most important thing about industrial software is the interdisciplinary basic research. This belongs to the Ministry of Science and Technology. Coincidentally, this is a typical Chinese moment. According to experience, the result of both ends is to play the ball, regardless of both sides. Very embarrassing, and there is another problem, that is, the concept of scientific research investment is not as good as hard. Remember the survey at the beginning? You see how many people intuitively think that hardware is actually more important. You see this Huawei incident, many articles and videos are talking about lithography machines. So many times, the above policy has been invested. In fact, what I like to see is that you take money to build a laboratory, buy a variety of high-end experimental devices, and you invest money to buy software. What effect does the software bring?It doesn’t look good at all. The leader came to visit and showed him nothing. Show him a bunch of computers, like an Internet cafe, how embarrassing! In fact, academician Ni Guangnan has also appealed before, saying that he wants everyone to change the unimportant thinking of this software. You must know that industrial software is as important as the industrial strength of machine tools and lithography machines.
Finally, let’s talk about China’s future. What can reassure everyone now is that we have begun to take it very seriously.During the epidemic on March 25, the Ministry of Industry and Information Technology gave the news through the joint epidemic prevention and control conference. A spokesman for the Ministry of Industry and Information Technology said that we will focus our efforts on solving the problem of “critical software” jamming necks and strive to promote the softwareization of industrial technology. At the same time, we also strongly support other policies. The Ministry of Finance issued an announcement on the corporate income tax for integrated circuit design and software industry. After the company made a profit, it directly exempted the tax for two years and reduced it by three years. Of course, after the policy, the more important thing is to rely on the Chinese young people in front of the screen. After the demographic dividend in China, the next step is the engineer dividend brought by the improvement of the population quality. China has the largest number of college students in the world, and will also have the world’s largest group of engineers in the future.
