I really just want to be a scholar

"Journal of Physics" is a half-monthly journal sponsored by the Xia State Physics Society. It is also the oldest and most influential physics comprehensive academic journal in Xia State. It is also the only Chinese physics academic journal included by SCI. In recent years, it has mainly focused on physics. results in cutting-edge fields.

Therefore, it is not surprising that this paper titled "Simulation Research on Sub-60 Devices Based on the Physical Mechanism of Cold Source Transistors" appeared in the "Journal of Physics". North Integrated Circuit and Chip Joint R&D Innovation Center".

This "Qingbei Integrated Circuit and Chip Joint R&D Innovation Center" should be a new institution established in early January this year. It is composed of a large number of experts and professors and more than 1 outstanding graduate students and doctoral students from Qingmu University and Beiyan University. There are many experienced engineers in chip manufacturers, whose main research direction is chip R&D and manufacturing.

If Qin Ke remembers correctly, Xu Qingyan, his former high school physics teacher and now an associate professor of physics at Qingmu University, serves as the deputy director of this R&D innovation center.

Qin Ke is currently looking at the issue of the journal in early April, which means that the paper was submitted at least in early March or even in late February.

The new institution has produced scientific research results less than two months after its establishment?Isn't this too fast?

Qin Ke looked carefully at the author column again, but did not find Xu Qingyan's name. There were two corresponding authors. I checked the Internet and found that they were both from Yanda. One was Yao Wencheng, the director of the Innovation Center, and the other was Fang Shiji, the deputy director.

There are also three people in the first work, all of whom are doctoral students of Yanda University.

As the deputy director of this innovation center, Xu Qingyan didn't sign the paper?
You must know that Xu Qingyan is a disciple of Jiang Weixian, an old academician, and he is best at physical materials and semiconductors.

Qin Ke looked at the paper carefully, only to find that it was a typical old medicine in a new bottle, and the core content was the sub-60 device "Dirac cold source transistor" developed by Yanda more than four years ago.

"Dirac cold source transistor" is a sub-60 ultra-low power transistor developed by the research team of Yanda University. It can break the Boltzmann limit and better solve the problem of sharp rise in power consumption when the integration of digital circuits increases. It is an outstanding scientific research achievement of carbon-based digital integrated circuits in China in recent years.But this is already a technical achievement four years ago, and the basic knowledge of chips acquired by Qin Ke through the system also has relevant documents.

Now look at this article "Simulation Research on Sub-60 Devices Based on the Physical Mechanism of Cold-source Transistors", the "Dirac cold-source transistor" has been improved, the power consumption has been reduced by about 5%, and the lowest sub-threshold swing has reached 33 mV /dec.But that's all, there are not many new highlights.

No wonder Xu Qingyan was not included in the list of authors. With Xu Qingyan's upright personality and scientific research achievements that he did not contribute to, he would never agree to sign his name.

Qin Ke checked the electronic content of each issue of this year through the official website of the "Acta Physica", and determined that this paper was the first scientific research achievement published by the "Qingbei Integrated Circuit and Chip Joint R&D Innovation Center" this year.

Qin Ke estimated that the "Qingbei Integrated Circuit and Chip Joint R&D and Innovation Center" was eager to produce a result to prove its value?
Or what's the inside story?
Qin Ke shook his head. He didn't care about these things, but he always respected Xu Qingyan and was interested in chip technology, so he paid more attention to this R&D and innovation center.

"What's the matter?" Ning Qingjun, who was next to him, had just finished the homework assigned by Professor Tian Jianlan. Seeing Qin Ke looking at the webpage with a strange expression, he couldn't help asking with concern.

"It's okay, it's just that I haven't seen Teacher Xu Qingyan much recently."

"Mr. Xu? Didn't Mr. Jiang mention last time that Mr. Xu went to work in some kind of chip R&D and innovation center?"

"Speaking of which, his personality is more suitable for scientific research. I hope he can show his talents in his new position. Okay, have you finished Professor Tian's homework? Then let's continue to complete the academic report for the Scientific Breakthrough Award." Qin Ke kissed the girl's tender little face, and reopened the half-written report on the proof of Polignac's conjecture.

Ning Qingyun pursed her bright red lips, with a slight smile on the corner of her mouth: "Okay."

……

At the same time, in the office of the Qingbei Integrated Circuit and Chip Joint R&D Innovation Center, Xu Qingyan was flipping through the difficult and difficult chip design software development progress report, his brows were tightly frowned, and he was not at all as Qin Ke imagined. refreshing.

It has been almost four months since I came to this R&D and innovation center, but Xu Qingyan felt like he was stuck in a quagmire, the more he struggled, the more powerless he became.

The R&D Innovation Center has one director and two deputy directors.

Director Yao Wencheng is an authority on chip materials of Yanda University. The "Dirac cold source transistor" developed by the team that year was hailed as "the new hope of carbon-based ultra-low power consumption CMOS integrated circuits", so he took it for granted to be in charge of " A research group in the direction of changing the process and materials of chip manufacturing.

The other deputy director, Fang Shiji, is also a professor of Yanda University and has a good relationship with Yao Wencheng. He first chose the research group in charge of "chip architecture and precision optics", so he left behind the most troublesome and difficult to produce results. Xu Qingyan is in charge of the research group in the direction of chip design software and microelectronic processing.

Microelectronics processing is okay. Xu Qingyan is an expert in semiconductors, and he has a little bit of microelectronics processing, but he is a pure rookie when it comes to chip design software.Facing informatics and software engineering, which he is not good at, Xu Qingyan’s work is extremely difficult, and he can only get familiar with these new fields by studying hard day and night.

But he couldn't protest against this division of labor.

Although he has made a lot of achievements in physical materials science, he became the youngest deputy director of a certain state-level key laboratory at the age of less than 30 years old more than ten years ago, but he later died because of the villain's accusation of plagiarism. He was expelled and had to go to Yingyuan Private High School as a physics teacher, missing the most golden ten years.Now even if he is invited back by Kiyoki University, and represents Kiyoki University as the deputy director in a key scientific research institution such as "Qingbei Integrated Circuit and Chip Joint R&D Innovation Center", how can we talk about the reputation and achievements in physical materials science in the past ten years? It is also inferior to Yao Wencheng.

Moreover, although the R&D Innovation Center is a cooperative institution between Qingmu and Yanda University, which nominally "sincerely cooperates to gather the scientific research strength of the two universities to solve the key problems of domestic chips", the open and secret struggle between the two universities has been deeply rooted for many years. Seeing that Xu Qingyan is working day and night Putting themselves into the project, Yao Wencheng and Fang Shiji, in order to grab the first scientific research results, actually took out the old results, packaged them and published them on the "Acta Physica" based on their relationship. This kind of atmosphere made Xu Qingyan feel helpless...

He also wants to produce scientific research results as soon as possible, but for the trust of Mr. Jiang, to solve the country's problem of being stuck in chips, not to overwhelm Yanda or anyone else.

This kind of inexplicable competition between like-minded people and different ways is the main reason why Xu Qingyan feels physically and mentally exhausted.

He put down the report in his hand, and rubbed his sore eyes that were bloodshot from staying up all night.

"If this continues, we won't be able to produce qualified chip design software in ten years..." Xu Qingyan murmured dryly and hoarsely.

The so-called chip design software, that is, EDA, or "Electronic Design Automation software", translates to electronic design automation software, which uses computers to complete the design, wiring, verification and simulation of integrated circuit chips.

It is known as the "mother of the chip" and is the most indispensable and important part of chip IC design.

At present, the world's three major EDA software manufacturers, Synopsys, Cadence, and Mentor Graphics, are all American companies. Their EDA occupies 99% of the market share in Xiaguo. The domestic EDA has only a share of less than 1%, and they cannot design high-end high-performance Chips can only be used in low-end scenarios such as single-chip microcomputers and control chips.

What Xu Qingyan has to do now is to design a full-process EDA that has completely independent intellectual property rights and can be used for high-end chip design.The above requirement is to at least be able to design high-performance chips with 7nm process technology.

The resources in his hands are more than [-] senior software development engineers, the independent EDA software code provided by Huapetal Company free of charge, and a large number of tests from several major domestic chip manufacturers for the simulation environment.

However, the EDA that Petal has developed for two or three years only has an imperfect main framework, engineering library, component library, and interface library, and the important PDK has not had time to get it.

Moreover, the mainstream technical architecture of EDA has been established with heavy patent barriers. Without authorization, Intel's instruction set cannot be used, and a new main software framework can only be established and improved based on the instruction set independently written by Petal.

However, the data provided by domestic chip manufacturers only reaches the 14nm process at most, and there is still a long way to go from the 7nm process. These data cannot be used in the 7nm process simulation simulation, let alone the most critical yield rate control in the later stage.

Even if Xu Qingyan wants to produce a 14nm process level EDA first, it is still very difficult.

Among all the difficult links, the most urgent need to be solved is the algorithm problem.

EDA has high requirements for algorithms. Without excellent algorithms added to the engineering library, it is like a soldier without weapons. No matter how strong you are trained, it is useless.At present, there are enough senior engineers in the EDA research group, and the level of writing code is first-class, but the innovation ability in algorithm is disappointing.

"Algorithm, algorithm!" Xu Qingyan paced back and forth in the office in annoyance, constantly thinking about the candidates who might solve this algorithm problem, and finally only two names remained.

He took a deep breath, picked up his cell phone, and dialed the number of his teacher, academician Jiang Weixian.

"Teacher, I have a problem and I need to ask Qin Ke and Ning Qingyun for help, is that okay?"

Jiang Weixian on the other end of the phone was silent for a while after listening to his disciple's detailed explanation.He didn't want Qin and Ke to fall into such a difficult and advanced subject that required countless energy, especially in the field of informatics.

"I heard that the two of them have recently submitted the final report of the Polignac conjecture project. There should be some time. It's just this EDA algorithm problem, Qin Ke and Ning Qingyun may not be able to solve it..."

"Teacher, I can only let Qin Ke and Ning Qingjun try it first. They are the computer geniuses who wrote the 'Lime Operating System' with their own efforts. Apart from them, I really can't think of a more suitable one." The candidate has been chosen."

Hearing Xu Qingyan's hoarse and dry voice, Su knew that this disciple would never ask for help unless it was absolutely necessary. After all, the old academician Jiang Weixian sighed: "You ask them for their opinions, and their wishes are the main ones. .”

"is teacher."

With the consent of Academician Jiang, Xu Qingyan couldn't sit still in the office. He didn't even bother to eat lunch, so he hurriedly put on his coat and went straight to Qingmu University.

……

After noon, after lunch, Qin Ke and Ning Qingyun walked hand in hand in the study room, and then returned to their seats together to continue completing the PPT for the Science Breakthrough Award report.

With the continuous improvement of the self-learning progress of the artificial intelligence of Xiaoguang, PPT production is basically competent. Qin Ke and Ning Qingyun only need to modify and perfect one or two, which saves a lot of time.

"It's done, you're done, just wait for the time to go to the meeting. Kiss me." Qin Ke stretched his waist, and was about to reach out to hug Ning Qingyun's slender waist, when there was a knock on the door of the study room Voice.

Ning Qingjun got up with a blushing face and ran to open the door, but unexpectedly found that it was Teacher Xu Qingyan who came.

Qin Ke also thought it was a coincidence. The two of them mentioned Teacher Xu in the morning, and Teacher Xu came.

Could it be that Mr. Xu's surname was Cao before?

Qin Ke stood up and greeted Ning Qingyun together: "Teacher Xu."

Qin Ke's eyes were sharp, and he noticed that Xu Qingyan was still wearing the same Chinese tunic suit, with the style buttons neatly buttoned and his hair combed meticulously. However, his face, which was originally as cold as a rock, could not hide the tiredness, and his eyes were bloodshot, as if he had stayed up all night. stayed up late.

Xu Qingyan asked: "Did I disturb your lunch break?"

Qin Ke knew that Xu Qingyan wasn't the kind of person who would come to chat with each other when he had nothing to do, so he smiled and said, "Qingyun and I don't have the habit of taking a lunch break. Mr. Xu, come in and sit down. Are you looking for us?"

Xu Qingyan nodded towards the two of them, adjusted his clothes again, and then walked in.

Qin Kela brought a chair for Xu Qingyan to sit down.

Xu Qingyan always speaks straight to the point, without any pleasantries, so he asked, "Qin Ke, Ning Qingyun, I heard that the Polignac conjecture project of you two has been completed? Will you be free recently?"

Qin Ke and Xu Qingyan have both teacher-student friendship and brother-teacher relationship, so they can be regarded as close people.

Teacher Xu is a bit rigid and not good at words, but he is serious and responsible in his work. At the beginning, he gave Qin Ke the physics Olympiad notes that he had compiled for nearly ten years, which benefited Qin Ke a lot. For the first time, he and Ning Qingyun spoke nicely in front of Old Academician Jiang.

With Qin Ke's character, when others treat him well, he always wants to repay him ten times to feel comfortable, so seeing that Xu Qingyan obviously has something to ask himself, Qin Ke didn't mention his hailstorm conjecture, and replied: "It's really not too busy recently. If there is anything we can help, just say it."

Xu Qingyan hesitated for a moment, but still said: "I really want to trouble you. Do you know EDA software?"

Both Qin Ke and Ning Qingyun took the elective course of integrated circuit design last semester, and they are no strangers to EDA software, so they all nodded at the moment: "Yes, chip design software."

Xu Qingyan looked slightly relaxed: "Now I have a problem with the EDA algorithm, and I need your help. Do you have time?"

At that moment, Xu Qingyan explained in detail the difficulties he was currently encountering.

Qin Ke has the chip technology knowledge of LV1, and has more experience in EDA algorithm, not to mention Xu Qingyan's request for help, he can't refuse.But before he could open his mouth, a system prompt sounded in his ear:
"Ding! You have a new mission to learn God!"

"Ding dong! Xueshen mission update 'It's time to start your chip journey'!"
