Hammer of Technology

"Sorry, Mr. Song, I still have something to do here. Let's talk later."

After finishing speaking, Ning Wei hung up the phone with one hand, and skillfully pulled the number into the blacklist.

Then he turned his head to look at Yu Xingwei and asked, "Brother Yu, it seems that you need to submit an application for fee reduction on your own initiative, and then the application for fee reduction indicates that you need to file for the record. How do you do this?"

"Log on to the website of the State Intellectual Property Office, there is a patent affairs service, register an account, and fill in your ID card to apply for a fee reduction. When applying, you need to provide an annual income certificate from the work unit or the county-level civil affairs department where the household registration is located. Or the certificate of economic difficulties issued by the township people's government or the sub-district office."

"Because we are a group of people without regular jobs, we can ask the school to issue your school certificate and explain that you have no job and no income, or you can ask the street office in your hometown to issue you a no-income certificate."

"But I did have some income recently, won't that affect it?"

Yu Xingwei smiled and said: "Of course it will not be affected. What is an annual income certificate? An annual income certificate is for a complete year. Now that 2021 is not over, naturally there will be no annual income certificate for 2021." At most, there is only the annual income certificate for 2020, so how much did you earn in 2020?"

"Ah! I understand!" Ning Wei exclaimed, "Thank you so much, Brother Yu!"

After finishing speaking, Ning Wei concentrated on preparing the application fee reduction materials.

Children from poor families start their own homes early and can save thousands of preferential policies, so they must be full.

Yu Xingwei shook his head violently, as if he could get rid of the rookie thoughts in his mind just now.

This kind of thinking can no longer exist, seeing Ning Wei's proficiency in pulling numbers into the blacklist with one hand makes him feel terrible.What's even more frightening is that the one who got blocked was a teacher from a top university in China. The most frightening thing is probably the comment just now...

It is not serious to evaluate Huaqing?

The difference between people is really too great. Where he used to be unattainable, this guy unexpectedly refused without giving anyone a chance.Like a scumbag.

Yu Xingwei regretted not filming this scene just now.

Otherwise, upload this video directly to Douyin, and there is a high probability that it will explode.

"No thanks, I'm going out first, if there's anything going on in the future, just look for me, President Ning!"

"Okay!" Ning Wei, who was immersed in how to save money, didn't notice that Yu Xingwei even changed his address.

……

Walking out of Ningwei's workshop, Yu Xingwei took out his mobile phone and sent a Moments full of emotion.

"I used to think you were too high to climb, but now I just think you are not serious!"

Surprisingly, there were several more replies in an instant.

"Finally figured it out? Stop being a dog licker?"

"Which goddess hurt you so deeply?"

"Brother, did you win the lottery?"

"..."

So much for these imaginative responses.

What made him even more speechless was that, inexplicably, a school girl who had pursued in graduate school also gave a reply under the circle of friends...

"Oh, man...you block me!"

What do these mean? !

So, is it that science students are not worthy of using the rhetorical technique of personification?

……

On the other side, Lu Changbin has already summoned the eight laboratory researchers selected by Ning Wei, and met in the small conference room.

This means that Ningwei's selection method is more realistic. There are no particularly busy bosses, so it is so easy to get everyone together.

"I called you here this time to tell you good news. Our laboratory is going to start a key project immediately, and we will start with a pre-allocated research and development fund of tens of millions!"

"Director Lu, what project is it?"

"EDA!"

"EDA?!"

088 There Are Different Opinions

"Professors, teachers, hello, everyone, thank you very much for joining our EDA project team with your trust in me. Today's meeting is to briefly talk about the design concept of our minimalist EDA, which has already given you a good idea of ​​the next work. Make a division."

In the small conference room on the fourth floor of the laboratory, Ning Wei was giving a report to everyone in the project team.

There is still pressure.

After all, apart from Yu Xingwei, the youngest one is also a round older than him.

"Let's put it this way, the EDA software that our project team is about to design is not as complicated as everyone imagines. I call it object-oriented EDA software design."

"Here I assume that every structure that can be made by existing technology is an object. I divide these objects into four types."

"They are units, the smallest structural unit that can be produced by existing technology, and this unit can be updated with technological breakthroughs."

"Group, a structure with a single function formed by the connection and arrangement of several elements.

"Group, several groups with the same or different functions are connected and arranged to form a structure that can independently complete a specific function."

"Container: A structure used to hold elements, groups, or clusters."

"Every object should contain two parts, properties and functions."

"Properties include not only the physical properties of the object, such as size, size, etc., but also the index and representation properties of the object, such as representative symbols, unified serial numbers, etc., and the layout properties of the object, such as connection methods and arrangement methods, etc. The function must have input parameters and a return value, which is a description of the object's function, such as single conduction, amplification, cutoff, etc."

Ning Wei explained his basic design concept to the project team members in comparison with the PPT that was released yesterday.

"From this perspective, you should see that our EDA design idea is actually very simple. On the one hand, we need to allow operators to easily position, arrange and connect symbols representing different types of objects on the design interface; on the other hand On the one hand, all the operations of the operator are actually the background of the computer calling the functions of the objects in series, and finally forming a large function process.”

"The above are the requirements for the design process. At the same time, our EDA software must have the simulation function. The EDA simulation process is the process of inputting parameters to the large function process and recording the feedback results, as well as the parameters passed between the various sub-processes and returned. value monitoring.

"The EDA instantiation process needs to generate a running script for the layout position and arrangement of objects in order to control the lithography machine for production and manufacturing."

"From the above requirements, we directly lead to the software structure."

"Object Repository: Objects used to define existing objects and store new designs for the future."

"Function Library: Functions for storing existing or future added objects."

"Design interface: for laying out, arranging, and connecting objects."

"Function concatenation: Concatenation and calling of functions used to arrange and concatenate objects in the manner in which they are concatenated and concatenated."

"Simulation and monitoring: used to send parameters to structures and detect the return value of each function node."

"Production function: Used to script the layout, arrangement and connection of objects to the lithography machine for production."

"In addition, because this is a brand new EDA software, we can't rely on the peripheral interface to introduce plug-ins, so we need to have a library that is different from other EDAs. This library corresponds to the object library. Every time we design a structure, we need to update an instruction set and supporting functions for this structure."

"In other words, every chip we design for a specific problem must have all-round support. This is where our product differentiation competition lies. Our products are not only for professional EDA designers of specific major manufacturers , My original intention is to let an elementary school child, after reading the manual, be able to use our software to design a usable chip.”

"After the launch of our software, the structure designed by professionals and the supporting instruction sets and functions can also be synchronized into our library after verification and review."

"Here is another requirement for our products, which is to have a built-in logical judgment ability for the structure. Simply put, what you ask for is what you get. In other words, users only need to be able to describe their needs more accurately. Our software It can automatically recommend the architecture and supporting configuration files that can fulfill this requirement!"

"I think everyone already understands the design concept of this software. It is simple, simple enough, and hardly requires any promotion costs."

"Do you have any questions?"

……

The project team members looked at each other.

Because it is difficult for people in the game to imagine the significance of the development of such an EDA software.

Do you use it as a toy for children?

That's right, simplicity can save a lot of promotion costs, but it also means that the practical value of this thing is not high!

The first is that it is almost impossible to design and simulate large and complex general-purpose chips, such as CPUs and GPUs.

The other is the application layer.

Ningwei means to bypass the existing various architectures and instruction sets, and it also involves compatibility issues.

In fact, there are ready-made solutions for AI chips at this stage, such as FPGA.

Different from Ningwei's idea, FPGA can be directly understood as a universal chip with a unified structure.

The user defines these gate circuits and the connections between memories by burning into the FPGA configuration file, and designs the hardware circuit of the FPGA with a hardware description language.Every time a programming is completed, the hardware circuit inside the FPGA has a definite connection method and has certain functions. The input data only needs to pass through each gate circuit in turn to get the output result.

This method is obviously more cost-effective than the ASIC model designed by Ningwei.Although FPGA also has its own shortcomings, for example, its performance is not as good as that of ASIC chips, and its price is also higher than that of ASIC chips.

The reason is that the deep learning algorithms of various artificial intelligences are in a period of rapid development, and the iterations are extremely fast. Every time the algorithm is changed, a new generation of dedicated chip structure must be updated in the object library.

Once the update is slow, it will fall behind...

Therefore, few people in the entire project team are optimistic about the prospects of this EDA software.

But everyone thinks differently.

Some people think it doesn't matter, anyway, after the funding is allocated, no matter what, everyone can earn some money.As for whether this software has practical value, there is nothing to care about.

Anyway, it is a special appropriation, so it is not in vain.

But there are also people who feel that this is inappropriate.

Public money is also money. Now that the laboratory has such a big plate, if they spend too much on their projects, other projects will have to cut funds.

Use this money on projects that are destined to be of little value, what about other valuable projects?

So after the silence, someone made a different voice.

"Ning Wei, can you explain, what is the original intention of designing this software? Where is the practical value?"

------------

089 It's much more interesting to change the goal!

Ning Wei once thought carefully about some additional functions after his brain mutation, and he felt that the focus of these functions was probably on guidance.

That is to say, whenever he comes into contact with useful knowledge points, his brain will be activated, and then he will react violently, associating many related knowledge lines.For other knowledge points, the brain has no response.

At present, the activation response of science subjects is relatively strong, such as mathematics, physics, especially quantum physics.

Liberal arts content is basically unresponsive, such as politics.

So when he decided to develop an EDA and began to search for EDA information, his brain was extremely active, and he gave a series of suggestions and highly directional solutions.

It's as if he thought of the turbulence algorithm from the NS equation at that time.

In other words, Ning Wei believes that this EDA must be useful.

As for how to use it, he still only has a vague idea. He planned to brainstorm with Lu Dongyi on WeChat, but that guy was obviously not interested in the EDA project, so he didn't bother with it at all.

So this question is also a headache for Ning Wei.

He is 90.00% sure that this EDA will be useful once the design is successful, but he is not sure about how to promote it and whether it can really realize its value, or he does not know how to word it to convince the person who raised this question.

……

"Professor Han, it's not convenient for me to answer your question directly. I can only tell you that this EDA is definitely useful. If we succeed enough, it can even change people's expectations for a series of electronic products in the future." Ning He answered carefully for every word.

The person who asked the question was Han Wenqing, the only researcher with a professorship among the people he selected.

Ning Wei chose him mainly because this professor not only participated in the development of large integrated circuits, but also had rich experience in software development.With an experienced and rigorous boss leading the team, his work can be much easier.

"That answer doesn't quite convince me."

Han Wenqing pushed the glasses, and his attitude was still rigorous: "If a product is successful enough, it should have found the advantages of the product compared with the auction at the design stage. Otherwise, is it too hasty to launch this project in such a hurry? Wasting time and money in the early stage , It is not good for the overall planning of the project. And I am most afraid that the final product developed will be meaningless.”

"You are just a student of mathematics. I admire your achievements in mathematics at this age, but crossing boundaries requires more than talent."

Ning Wei thought for a while and replied: "Professor Han, how could it be meaningless? First of all, you can't deny that domestic EDA tools are not complete, can you? EDA software should cover all aspects of IC design, wiring, verification and simulation. The current domestic A lot of EDA only involves a part of it.”

"Secondly, I don't agree with the waste of funds. I don't know if you understand the turbulence algorithm project. From the design to the development of this algorithm, I didn't take a penny of research and development funds from the school. Even when it entered the testing stage, the laboratory was going to give me 50 I have rejected all the R&D funds. Specifically, for the EDA project, most of the currently planned funds are used for the rental and purchase of experimental equipment.”

"These devices will be useful in the future. Not to mention that if we can design a nearly omnipotent EDA software according to the plan, it can be regarded as accumulating experience for the next generation of EDA software upgrades, right? Is it because it is not as good as other similar products now?" , just don’t do it all the time? Although it’s a bit presumptuous, I still want to tell you that I attach great importance to this project and I am very confident. If you think it’s a waste of time, you can quit this project. I won’t be looking for more reason to convince you."

Ning Wei said calmly.

He likes Han Wenqing's experience, but he doesn't necessarily need it.

It's just that he's a little tired.

Anyway, being young, being able to survive is his biggest asset now.

"Okay, I reserve my point of view and withdraw from this project. In addition, I will reflect my point of view to the leaders of the laboratory and the school. Your project is suspected of wasting R&D funds. I don't deny its innovativeness, but Doubt its practicality." Han Wenqing said calmly.

"This is your right, well, are there any other teachers who have decided to quit?" Ning Wei asked.
