I really just want to be a scholar

On the second day of the May Day holiday, it was raining continuously outside the window, which was not a suitable weather for going out for fun.

So Qin Ke and Ning Qingyun didn't go out today, but stayed in Xingguang Mingyuan's new home to conduct research together.

At present, the thesis on tomato breeding has been completed, the patent application process is speeding up, and the academic report materials for the Scientific Breakthrough Award have also been finalized.Now the research topics that the two of them are working on are only Hail conjecture and EDA software optimization.

——Oh, there is also a topic of desert sweet potatoes, but it is estimated that it will take another one or two months to start. After all, collecting sweet potato seeds of different varieties around the world is really time-consuming.The hybrid breeding of desert sweet potatoes requires more than ten varieties to be bred repeatedly, and the A+ level knowledge does not mark the specific name of sweet potato seeds, so it can only be obtained by Qin Ke trying to plant varieties from all over the world in the virtual scientific research experiment center. Tested one by one.

After typing the last word of the EDA optimization idea, Qin Ke closed his laptop, stretched, and got up to make a cup of lemon tea for Ning Qingyun.

Passing by the window, Qin Ke glanced out of the window, and saw that everything he could see was rain, and there were very few pedestrians outside.This year, there is a lot of rain in the north. I don’t know if the J-92 breakwater project of Professor Duan has started to be promoted?

Qin Ke was particularly impressed with this super-large project that he participated in for the first time. Well, send a message to Professor Duan to ask questions when you have time.

When Qin Ke made lemon tea and returned to the study, Ning Qingyun was still staring intently at her fruit laptop, and her slender, white and tender little fingers were typing on the keyboard quickly, perfecting a small algorithm of EDA.

In the past few days, Qin Ke has basically taught Ning Qingyun the algorithm knowledge related to informatics and chip design that he has mastered through "thinking resonance", and Ning Qingyun officially practiced on the computer today.

After Qin Ke explained the main idea of ​​a certain small algorithm to her, Ning Qingyun enthusiastically stated that she would perfect it independently, and compiled the code by herself, without the help of Qin Ke and Shimmer, to verify her knowledge of the algorithm. The degree of mastery is regarded as a "graduation test".

Qin Ke naturally wouldn't object, anyway, it's a small algorithm with only a few hundred lines of code, and with the main idea, Ning Qingyun can handle it completely.And it is true that it is necessary to apply what you have learned in order to truly grasp the essence of improving the algorithm with mathematical modeling thinking.

What's more, this kind of earnestness and concentration is also the cute and attractive advantage of Ning Qingyun.

Qin Ke sat back beside the girl, propped his chin and stared at her fair and tender side face.

Girls usually listen to Qin Ke's words at home, with waist-length hair that is silky and waterfall-like, so the originally somewhat proud and cold temperament turned into a charming and charming.

Ning Qingyun's appearance still remained the same as on her birthday, with her soft and delicate facial lines, bright and beautiful phoenix eyes like stars, slender eyebrows with graceful curvature, fair and lovely tall nose bridge, ruddy and tender lips, slightly The pointed and rounded little chin, and the white and slender little fingers typing on the keyboard...

It can be said that there is beauty everywhere, and there is no beauty in every place. Even after watching it countless times, Qin Ke still has a feeling of thumping.

In Qin Ke's eyes, everything about his little cabbage is perfect, so cute, so attractive to him.

For example, her focused expression staring at the screen at this time, her slender eyebrows and her tight red lips inadvertently frowned when she was meditating seriously, will make people unable to help but give birth to a kind of love that wants to hurt her to the bone. .

It is said that love is first born from the appreciation of appearance and figure, but Qin Ke remembered that when he was at the same table with Ning Qingyun, he actually had no special feelings for her, because at that time Qin Ke only had eyes for learning, only the stars and the sea, He doesn't care if the girls are beautiful or not.It wasn't until I had been in contact with Ning Qingyun for a long time, and was attracted by her pure and shy, serious and strong temperament and personality, that I opened a brand new door, knew how to appreciate the beauty of girls, and then was pleasantly surprised to find that I like her. Girls seem to be the most beautiful and perfect girls in the world, so there is a feeling of getting a treasure by accident and wanting to cherish it even more.

Until now, even though he has truly possessed the girl in front of him, his feeling is still very strong.

He admired Ning Qingyun quietly like this, his heart was full of tranquility and warmth.

But soon he found that the girl's pink and tender face, which was like top-grade white porcelain, was quietly stained with a layer of blush, presumably it was his unscrupulous gaze that made the girl shy.

Sure enough, Ning Qingyun turned her head and asked with a blushing face and big beautiful eyes: "You...why are you looking at me all the time?"

Her voice has a cute nasal tone, and her tone seems to be protesting, but also seems to be acting like a baby.

Qin Ke was happy, and put on a rogue face: "I just like to see you, can't I?"

The girl looked away shyly, and said in a low voice, "I... haven't gotten tired of watching it for a few years?"

"Let's not say I've only watched it for two or three years, even if I watch it for a lifetime, I won't get tired of it, the more I watch it, the more I like it."

"You will come to coax me with sweet words... I won't be fooled." Ning Qingyun said this, with a sweet and happy taste in his tone, and there were also rippling water in his eyes. The innocence of the past is now a little more charming.

Qin Ke felt that he really loved this girl so much, he couldn't help but hugged her slender waist tightly, and gently pecked her delicate lips.

"Jun'er, you've been facing the computer for so long, do you want to take a break?"

Ning Qingyun's face became even redder, hotter than the evening glow, she lowered her head and said weakly: "Isn't it all...not all...it's broad daylight now...can we wait until tonight..."

Qin Ke almost laughed, but Ning Qingyun misunderstood.

In fact, Qin Ke is such a person who doesn't cherish his girlfriend. With Ning Qingyun's relatively delicate physique, every time he "visits" the room with him, he will be exhausted. , physical fitness can not be fully recovered, the look is still a little lazy, and the body is limp, how dare Qin Ke take her to "visit" the room now?
At least let her slow down for a day.

Qin Ke pretended to be embarrassed and hesitated, and after a while he "reluctantly" said: "Okay, then I will 'visit' the room with you in the evening, but now you really need to take a break, sitting for a long time and facing the computer screen for a long time Neither is good."

"Yeah." The blush on Ning Qingyun's face slowly faded, and she obediently picked up the lemon tea that Qin Ke had made for him, and took a small sip while walking slowly in the study .

The kitten-shaped platinum diamond ring on the ring finger of the girl's left hand was extraordinarily shiny against the transparent glass, and the corners of Qin Ke's mouth curled up a little proudly and warmly.

Ever since she put on the ring on her birthday, Ning Qingyun has never taken it off except for taking a bath and washing her hair.

This kind of obediently obeying the small details that became his "property" will always make Qin Ke feel particularly happy.

When Ning Qingyun finished drinking the lemon tea and put down the cup, Qin Ke went to hold her hand and walked together in the new house.

"EDA software is indeed very important. Last semester, we took an elective course on integrated circuit design. Didn't the teacher say that? With the help of automated design of EDA software, the design cost of 14nm chips exceeds 10 billion yuan, and the design cost of 7nm chips is even higher. It costs more than 30 billion yuan. If there is no EDA assistance, if it is all manual, even if engineers from all over the country spend hundreds of billions of yuan, it may not be able to design it. At present, the EDA in our country is still very weak, and it is impossible to design high-end high-performance products. Chips, this problem is very challenging and meaningful, even if Teacher Xu doesn’t come to you, I will probably carry out this topic in the future.”

Qin Ke felt the delicate softness between the girl's fingers while talking about their EDA project:

"If you want to develop an easy-to-use EDA, programming is only secondary. The key is to know the chip design and chip manufacturing process well. Teacher Xu's information has been uploaded last night. I took a rough look. I will sort out the parts that need you to look at, and you can look at it when the time comes."

"Of course, the development and update of EDA software is inseparable from the chip manufacturing process. It also requires the close cooperation of chip manufacturers, especially fabs, to provide suitable data for simulation. Teacher Xu will solve this problem, so we don't have to worry about it. gone."

"This time the EDA is provided by the petals, and the completion is less than half, but the main frame is not bad, I plan to re-optimize it, redefine the main frame and technical architecture, just like the lime operating system, to achieve modularization Transformation, so that in the future, whether it is facing the 14nm process technology, or 7nm, 5nm, 3nm, 2nm or even 1nm, it can be applied, just need to match the design module and the algorithm module in the engineering library."

"Originally I really wanted to develop an ideal full-process EDA. It is estimated that it will be impossible in three to five years. The amount of code will not be smaller than that of the Lime operating system. But now there is a 'twilight' that can automatically program. I plan to let the two of us Responsible for writing the rules and framework, and then the team at Mr. Xu’s side will fill in the details, and finally hand over to 'Shimmer' to write the code, which can greatly shorten the development progress..."

Ning Qingyun didn't speak, but just quietly listened to Qin Ke's plan, but a slight smile could not help but appear on the corner of her mouth.

Whenever she does a project together, she always feels an indescribable sense of satisfaction. The feeling of walking side by side and working towards a goal together is so wonderful, which makes her feel happy.And she really likes to see Qin Ke's eloquent and confident appearance, so she can't help but feel admiration in her heart.

Probably this is the only boy in the world who can convince her and even look up to him with admiration.

……

EDA is indeed an indispensable key software in chip design. It covers almost the entire process of chip design, including design, simulation, verification and other links.Generally speaking, EDA also has subdivided fields, and different manufacturers have their own emphasis. There are even EDAs that are only responsible for a certain link, such as IC design, electronic circuit design, PCB design, etc.

The chip design team often has to switch between different EDAs. After repeated design and verification by the fab, a complete chip layout file will be generated and delivered to the fab for production.

This is the pre-design work for the birth of a chip.

The specific requirements of EDA are too high and very complicated, and there is no room for any mistakes or omissions, resulting in a particularly high investment in research and development.Another difficulty is that the three giants have basically monopolized the interface IP through intellectual property rights. Once EDA leaves these interface IPs, it is equivalent to rebuilding a new front. just work.

The semi-finished EDA of petals is taking such a road. Fortunately, the superiors strongly support it regardless of the cost, and the domestic fabs also express their full cooperation, which makes this extremely difficult road vaguely see a glimmer of hope for success.

But it is only a "slippery trace". There is still a lack of domestic chip talents, especially all-round chip talents, which makes it difficult for Xu Qingyan's project team, which has assembled the national chip design and software development elites.

However, for Qin Ke, he has the design ideas and algorithm ideas given by the system in his hands, and he has a sound basic knowledge of chips and informatics programming knowledge, plus a master-level mathematical modeling thinking level. The difficulty of going through this path is greatly reduced.

Don't underestimate the design idea, it is equivalent to someone pointing out the direction that is sure to be successful, and pointing out every key node along the way. You only need to walk out this road to success step by step, the difficulty is not the same at all And language.

Especially the idea of ​​the algorithm, as long as the details are perfected, it is enough to form the most important engineering library in EDA.The so-called engineering library mainly refers to standard cell library, reusable circuit module library, IP library, etc.

Qin Ke readjusted the framework of the original petal EDA to make it conform to his own modular design ideas, and kept the original results as much as possible, including process parameter library, component graphic symbol library, component model library, etc. Then formulate detailed rules for each module, and send each part to Xu Qingyan for him to organize his team of engineers to fill in and improve according to the rules.

And Ning Qingyun is mainly responsible for improving the algorithm part. With the guidance provided by Qin Ke, it is much easier for Ning Qingyun to improve the details of the algorithm, and he will discuss it with Qin Ke if it is really difficult.

Time passed in such a hurry, and a month passed in a blink of an eye, and the time entered the end of May.

The anxiety and irritability in Xu Qingyan's heart gradually disappeared. Qin Ke and Ning Qingyun's supernatural performance far exceeded his expectations, which surprised him very much, and he fully supported these two young students.

The new EDA design idea originally sent by Qin Ke made Xu Qingyan's project team a little suspicious. After all, it is not the same as the current mainstream EDA software, but Xu Qingyan insisted on redesigning the plan according to this design idea. reluctantly complied.

But soon they were shocked by the detailed rules forwarded by Xu Qingyan again and again. The design ideas that looked at the sky and the sky, under the enrichment of the detailed rules of these modules, gradually formed a big tree with luxuriant leaves. There is a tendency to soar into the sky.

When they heard that these materials were designed by a chip expert code-named "Q" specially arranged by the superior, everyone in the team was even more amazed.

You must know that there are no more than [-] such top experts who only have a code name and their identities are strictly kept secret!I didn't expect Director Xu to apply for such strong support!

The whole team had no objection and cooperated with all their strength, which made the EDA project move forward rapidly.

In particular, the intelligent algorithms sent by "Q" one after another, and the well-written engineering library codes are continuously provided, which amazed them even more, and even privately discussed that this expert code-named "Q" is probably a scientific research team. ...

In any case, "Q"'s superb performance made the entire project team see the hope of success, and they were in high spirits. They followed the instructions of "Q" and devoted themselves to this project day and night.

Although "Q" never showed up, and never had a half-sentence communication outside of work, in the team, he has faintly become the core of the team.

……

Qin Ke and Ning Qingyun maintained the rhythm of study, class, self-study, and project. Most of their free time was devoted to this EDA project. They didn't even know that the latest issue of "Annual of Mathematics" had been released, Their "Proof of Polignac's Conjecture" and "A New Conjecture About the Relationship between Prime Numbers and Riemann Spherical Curves" were put on the editor's recommendation of the cover.

"Besides amazed, we really don't know what adjectives to use to describe our mood at the moment, let's celebrate, let's revel, a great conjecture that has been stuck in the history of mathematics for nearly a hundred years has since become'Pollignac- Qin Ning's theorem'!"

——The editorial department of "Annual Journal of Mathematics".

The mathematics community of the whole world is once again a sensation.
