Hammer of Technology

Although all the members of the project team in the conference room were older than him, Ningwei was no longer nervous after a short confrontation with the old professor, and even found the feeling of a project leader.

He doesn't dislike Professor Han's rigor. In fact, with Professor Han's qualifications, he doubts why he didn't participate in other key projects, but now he probably understands.

Very stubborn, and the way of thinking is relatively conservative and moderate, but also very frank.

This kind of personality is actually a double-edged sword. If you achieve outstanding results, you may not really be able to leave your name in history.But most of them can only be depressed and unsuccessful.

No one said a word.

Han Wenqing stood up silently, and walked out of the meeting room.

"Okay, then let's go directly into groups. Director Lu approved two laboratories for this project. One is in charge of the front end, and Professor Xu is in charge of it, and I am in charge of the back end. Sign up for the corresponding group."

"As for the programming requirements, I have already written them in the laboratory manual of this project. Please read them carefully. I emphasize that please use a unified standard for function naming, and the places that need to be documented must not be omitted, and Be as specific as possible.”

"Before submitting the code after work every day, please review each other within each group. The standard is that as long as one person in the code group completed that day cannot understand the code through the function name and class name, and cannot explain clearly, these codes are not allowed to be submitted. Need to call back Rewrite. If it is submitted, and the team leader or I feel that the code is not good enough, then this batch of code will not only be deleted, but also become a task for the whole team to pass the approval! The whole team needs to work overtime to make up for it.”

"All functional code modules need detailed comments. The standard is that if we add people to the project in the future, they can get started immediately, instead of thinking that the code we typed before is a pile of shit."

"Do you have any other questions?"

No one answered.

"Well, today's meeting is over. In addition, I will ask the accountant to directly accrue 5.00% of the first batch of appropriation R&D funds as a bonus for each stage. This money will be selected by the two teams in this stage. A total of four people will distribute 80.00% of it, and the others will share 20.00% on average."

"I am not involved in the allocation of bonuses for this project. This will be the case at every stage in the future. I hope everyone can work together to complete this project as soon as possible."

"Now everyone can choose to do the front-end or the back-end according to their own abilities. But this is not a one-time choice, and it will be adjusted according to the project situation at any time."

……

"President Xiao Ning, don't argue with Professor Han, he is just like this, he is not bad-hearted, he just likes to be serious, and he doesn't get along well with many people."

After the meeting ended, Yu Xingwei approached Ning Wei and said.

"I can feel it. But do you think our EDA project makes sense?"

"How can it be meaningless? Who dares to say that EDA software that involves almost all links is meaningless? I, Yu Xingwei, are the first to refuse!"

"what!"

Hearing this, Ning Wei smiled...

"Brother Yu!"

"Ok?"

"I figured out why the treacherous ministers in the history books are better! In addition, when I prove that this project is indeed meaningful, I will invite that Professor Zai Han back to follow up on this project after I leave. Project. What do you think?"

"Ahem, then Professor Han may become bald after studying so many codes from scratch, no, you have to leave..."

Ning Wei turned his face sideways, interrupted Yu Xingwei, and said, "That's good! Who asked him to question us? Let's just change the goal of the project and work hard together to make old Han bald. Think about it this way , full of energy in an instant, right?"

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

090 Stand firm

Ning Wei acted calmly, but there was still a grudge in his heart.

Mainly because of Han Wenqing's sentence "You are just a math student!"

Does this look down on mathematics?

Computers, communications... and even the entire Internet system, how can it be without the support of mathematics?

Ok?

And chip material?

Suddenly again, several sets of formulas suddenly appeared in Ning Wei's mind.

V^=Vc+α（Vo-Ve）……

Atomic velocities, centroid velocities, control coefficients...

It's amazing.

These seem to involve arrays of carbon nanotubes, a new post-Moore alternative to silicon as the material of choice for semiconductor chips, also with the help of mathematics...

Ning Wei shook his head resolutely, letting go of the eagerness in his heart.

He still understands the truth that more greed can't be chewed.

Yes, Ning Wei was persuaded.

There is no need to be in a hurry to be competitive. His current task is to solve the two projects of turbulence algorithm and EDA software before graduating from senior year.

As for the others, Ning Wei feels that he can't continue to think about it now.

Of course, the formulas that just surfaced are still engraved in his mind.

……

In fact, Ning Wei didn't have time to get angry with the old-fashioned Professor Han.

He didn't know whether Han Wenqing had really found a leader to reduce the investment in the EDA software project, but the first project funds were still allocated, totaling 400 million.

According to Director Lu, this is the first phase of funding for the project, and the money was allocated through the Provincial Department of Science and Technology.

Ning Wei approached the laboratory's financial department to accrue 20 yuan as the first-stage bonus as promised at the meeting.

It's not a big prize, but it can really stimulate the enthusiasm of everyone in the project team.

For Ning Wei, it probably means that life is more fulfilling.

From a senior student to waking up every day to manage two project teams, three laboratories, and more than a dozen associate professors, researchers, and doctoral students, how exciting it feels, probably no undergraduate has ever experienced it.

But for Ning Wei, it was a rare experience.

Different from fighting alone before, in Luo Xiang's words, it is now a gang committing crimes, so more attention should be paid to the division of labor and efficiency.

In fact, Ning Wei would also like to thank Han Wenqing for his face-saving confrontation at the opening meeting of the EDA software project team, allowing him to put forward stricter requirements without any scruples.

In the first week, he learned from Yu Xingwei that Daojia complained a lot.

Especially the daily interactive review session.

Whether this face is given or not is a headache.

Don’t give it, everyone looks down and sees you, give it, if the submission review fails, the abandoned code becomes the task of the whole team, and the team leader will lose face if the progress is slowed down.

What's more, the more obsolete code, the bonus is definitely gone.

In addition to document writing.

As we all know, serious programmers hate writing documents, but at the same time, serious programmers also hate other colleagues who don't write documents.

Well now, points will definitely be deducted if you don’t write the document.

After writing the document, if the code is discarded, it is tantamount to writing for nothing.

So, with the support of Lu Changbin's iron fist, after two weeks of persistence, a bunch of talented people in the project team just got used to it.

Of course, there must be Ning Wei's credit.

The codes and documents submitted by everyone are in the encrypted area of ​​the same server, because the front-end and the back-end need to communicate at any time, so the team leader can also use his account password to view other people's codes and documents.

Ning Wei's code and documents were displayed in front of everyone.

It is said that the text is the first and the military is the second, but the code and the document can really be compared.

Strict function names and class names make the code look clear at a glance. Even so, there are detailed comments and various explanatory documents, especially the interface documents...

After that, Yu Xingwei contributed a complete set of explanatory documents made by Ning Wei in the turbulence algorithm project team. After reading it, all members of the EDA project team were completely convinced.

"Hey, such a student, Lao Lu, still wants to keep him in the laboratory to study for a Ph. D. Who is the nerve to teach? Just give him a Ph.D. diploma! Or throw him back to the Mathematical Academy and let those shameless people in the Mathematical Academy go Grab people! Then again, when did our school’s mathematics department become so good? Can we actually cultivate such fairy students?”

This is the comment given by Associate Professor Xu Zhiyuan, the front-end team leader, after reading these codes and documents, shaking his head.

In any case, Ning Wei has firmly established himself as the head of the EDA project team.

After all, in the field of scientific research, there are projects that can attract funds, and the status is naturally superior to others. In addition, the ability and attitude displayed are there, and Ning Wei's status as a senior student has become a bonus item.

They are all in their tens of years, so they can't be compared too badly by a student...

In this way, with everyone's efforts, the time has entered December, the real month of postgraduate entrance examination, and the month when Jiangcheng officially enters winter.

……

The winter in Jiangcheng is actually not too cold in terms of temperature.

It generally hovers between 0 and 10 degrees, but once it rains and winds up, it's really unbearable.

The damp and cold in the south is a pain that northerners cannot understand.

It was the bone-chilling coldness that slowly seeped into the bone marrow from the outside to the inside, and even wearing a thick cotton coat, it couldn't be blocked at all.

More importantly, there is no collective heating in the south, which means that indoors and outdoors look the same, except for warm quilts, damp and cold are everywhere.

Turning on the air conditioner can be slightly better, but if you stay in a small air-conditioned room for a long time, it is easy to get dizzy.

What's more frightening is that the final exam of the first half of the semester is approaching quietly.

The postgraduate entrance examination month, coupled with the bonus near the end of the period, made the study room in the school quietly tight.

Especially the general plan with central air-conditioning and warmth like spring has become increasingly difficult to make an appointment.

This is what Xu Ruixuan feels the most.

Jiangda Library can reserve seats for the next day from 22:45 to 23:50.

Half a month ago, he was able to log in three or four accounts by himself at around 23:22 the day before to reserve the seats connected together in the study room of the general map. Within minutes, all the positions were robbed...

Not only the general drawing, but also the letter drawing and construction drawing are in the same situation.

This was enough to make Xu Ruixuan grit his teeth with hatred.

After all, for a postgraduate entrance examination party like my girlfriend, seats in the self-study area of ​​the general map are just needed.Moreover, the postgraduate entrance examination was approaching, and the two had little time to date. The study room, the place where love began, was the closest place Xu Ruixuan could be to Xu Mo every day.

What made him even more depressed was that Ning Wei seldom went back to the dormitory recently.

When it was hot, I would come back every day to take a shower, and when the weather turned cold, I changed it to once every two or three days and always picked a few people to go to class...

This is really bullying.

After all, the topics for the thesis of the three of them have not been decided yet!

How could this guy refuse to save him?

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

091 Only those who are capable can be fathers!

The phone kept vibrating next to her, but Ning Wei pretended not to notice it.

Recently, he has almost completely let go of the turbulence algorithm and devoted himself to the EDA software.

There is no problem with the turbulence algorithm. In fact, the reason why this project has been conducting internal testing in the laboratory and has not contacted external parties for large-scale public testing is also because of technical bottlenecks.

At present, the misjudgment rate of the turbulence algorithm in the laboratory is stable at about [-]/[-], and it cannot be further reduced.

An error rate of 12306 per [-] does not sound high, but if it is applied to the servers of ticketing websites and apps like [-], it is terrible.

The user base is too large.

For every 12306 million people who use 1800 to book tickets, more than 12306 people may be wrongly judged as malicious crawlers and punished. This must be a bad thing.Not to mention that more than [-] million people use the [-] booking system every year?

There is more than one long vacation!

It's not that Ning Wei and the three assistant researchers have thought of a way. They brainstormed together and iterated the algorithm twice, but they still couldn't reduce the error rate of the laboratory internal test.

This made Ning Wei feel that further breakthroughs in the turbulence algorithm may require him to further deepen his understanding of the entire system. There are enough data to analyze, maybe some clues can be found from these data.

So Ning Wei no longer pays attention to the turbulence algorithm. After all, no one in the EDA software project team knows the structure and difficulties of this software better than him.

The biggest difficulty is actually to simplify the chip design.

Give a simple example.

When using mainstream EDA software for back-end design, the first step is generally to set the standard library.

The required data can be roughly divided into three categories, namely the logical layer, physical layer and design.

These three categories can be subdivided into six types of files, including process files, unit libraries, sub-libraries, netlist files after synthesis, TDF files that constrain Pad positions, and timing constraint files given after synthesis.

Then there is the overall layout of the chip, which is an important step that directly affects the chip area, speed signal integrity and design cycle.It is necessary to allocate corresponding positions for modules, input and output interfaces, power pads, etc.

Next comes clock tree synthesis, which is also a big challenge.Think about it, after gathering tens of millions or even hundreds of millions of transistors, it is not easy to transmit the clock signal to every local area of ​​the chip with zero deviation.
