Rebirth 2010, the best

Chapter 295 Blossom

"S simulation is performed on VGA and DA, and the output standing wave ratio simulation results are shown in the figure. In the 1.6-1.65GHz frequency band, the output..."

"Teacher Lu, stop for a moment."

There were about thirty people sitting in the large conference room of the Eighth Academy of AVIC.

After hearing this voice, many people, including Zhao Lijun, subconsciously looked at the two men and women in simple suits sitting in the front row.

The one who called a halt was the middle-aged man with glasses.

As for the identities of these two people, Jiang Minglu, who is responsible for coordinating this project, has already introduced them to everyone at the beginning of the briefing.

These two are from the National Security Bureau, codenamed Ms. Zhao and Mr. Qian.

They also didn't know whether the names and surnames were real or not. After all, the surnames of these two people were next to each other in the Hundred Family Surnames. But no one took it seriously. They just wanted to know their identities.

Mr. Qian stopped Lu Yao from talking and said directly:
"The following model data is confidential. Please omit it."

"Uh……"

Lu Yao on the stage looked a little surprised, but still nodded obediently:
"Okay. In short, in my model, after all the data are simulated and verified, we can draw the conclusion that CMOS technology must be the trend of the future, thanks to its perfect integration with digital baseband circuits, low cost, low power consumption and high integration. At the same time, with the advancement of technology, its cutoff frequency will become higher and higher. In the future, the integrated RF and baseband system-on-chip will be the key research direction in the field of integrated circuits.

Furthermore, I think this RF chip will also play a positive role in the aerospace field. It can provide high-precision positioning, orbit determination, attitude control and other services for spacecraft. It can also provide a large amount of accurate data in the launch and measurement and control of spacecraft. It can also provide more accurate data for the synchronization and coordination of multiple launch satellites. Most importantly, in theory, it can provide stable signal transmission for deep space missions..."

He said, and the people below were listening.

Although the aerospace field and a semiconductor chip may seem to have nothing in common at first glance, in fact, the fields of science and technology are sometimes interconnected.

Including Zhao Lijun and other senior researchers sitting in the back, everyone was quite puzzled before attending this meeting that was temporarily called in today.

This is especially true when I see that the person giving the explanation today is a young man.

But as Lu Yao unfolded the RDSS RF chip model bit by bit, everyone gradually put away their playful mentality.

Aerospace technology can be said to be a reflection of a country's comprehensive scientific and technological capabilities.

Everything about aerospace engineering is high-tech and advanced application of various scientific fields, and it is also the category that is most likely to expose the country's scientific and technological shortcomings.

They may not understand how to design a chip or write code... but they are very familiar with the role a chip plays in a certain project or component.

And the model in the hands of the young man in front of me...

Carefully recalling everything that happened at today's briefing, everyone had to admit that it was...excellent.

It is not just excellent. Although we cannot get the specific data, from the description, unless this young man has beautified the chip, otherwise... its performance is likely to be excellent beyond the times!

Is it really that exaggerated?
Many people began to feel doubtful.

But if you think about it carefully, it probably won't be the case.

After all, several leaders of the institute were present at the briefing, and they should know more details than he did.

Even those of us who haven't obtained the specific data think it is excellent. There is no reason for them not to see something deeper.

What's more, this young man came directly to explain.

This “explanation” is very telling.

Unfortunately, the level is not high enough to get more detailed data.

Otherwise... I really want to see what kind of thing this young man comes up with.

Thinking and listening.

Soon, Lu Yao took the initiative to end the briefing after three interventions from Ms. Zhao and Mr. Qian.

"thank you all."

Following Lu Yao's bow, the two men stood up immediately.

Then he nodded politely to the director and made a "please" gesture to Lu Yao, appearing extremely polite.

Lu Yao was stunned...

I was a little surprised that they didn't let me communicate with these people. After all, I haven't "slapped myself in the face" yet.

But they had already asked him to leave, so there was nothing he could do, so he just followed the two of them out.

Before leaving, he heard a voice coming from the conference room:
"What do you think? Please share your thoughts now..."

……

in an office.

"Thank you, Sister Zhao."

Lu Yao thanked him politely and took the teacup.

Ms. Zhao smiled slightly:
"Drink more, your throat is a little hoarse."

"Ah."

Lu Yao responded again and suddenly said:

“Why don’t you let me communicate with them?”

Hearing this, unlike Mr. Qian, Ms. Zhao said very straightforwardly:
"Captain Zheng doesn't allow it. He's afraid you might let something slip, so the task we've been given is to stop everything you've said today related to data and design. And this is also the main reason why you weren't allowed to make a PPT report."

"..."

Lu Yao glanced at Mr. Qian and shook his head speechlessly:

"If you had told me earlier, I wouldn't have stayed up all night. I worked on this report until two or three o'clock yesterday."

"It was a sudden notice this morning."

Ms. Zhao did not hide it from him, and seemed to be very clear about his and Zheng Xiaofan's plan, and continued:

"The purpose of letting Zhao Lijun know has been achieved. This afternoon is the time when you will really need to provide detailed data explanations."

"Um……"

Lu Yao nodded without any surprise, and then fell into deep thought again.

RDSS chip, he doesn't need to prepare anything.

All the data has long been memorized, including its subsequent trends.

His main purpose now is to get the specific data of the tape-out after this briefing is over.

As long as he gets the tape-out data, he will know which direction to go next.

And the secondary purpose... is Zhao Lijun.

During the entire speech just now, Lu Yao's eyes would fall on him from time to time.

But I have to admit that the other party actually behaved very calmly.

There was no sign of hostility or other emotions towards me...except that when he first came in and saw me, he looked at me with surprise, there was nothing else.

Lu Yao couldn’t guess for a moment...whether Luo Xuewei would provoke the other party as he did in the processed chat screenshot he sent to Zheng Xiaofan.

If it's stimulating, then it means... at least he will feel uncomfortable when he sees me.

But if there is no stimulation, it means that his work this morning was in vain.

After thinking for a while, he said:
"I'll give Brother Fan a call."

Hearing this, the two did not object.

So, Lu Yao directly called Zheng Xiaofan:

"Hey, Brother Fan."

"Well, are you done?"

"Correct."

"Is Zhao Lijun here?"

"Yes... but I can't tell if he has any hostility towards me. So I was thinking, should I take the initiative to send a message to Luo Xuewei."

"...What do you want to do?"

"Is such that……"

Lu Yao roughly expressed what was in his mind, and when Ms. Zhao and Mr. Qian heard his thoughts, they looked him up and down.

The meaning is unclear.

As for Zheng Xiaofan, after a moment of silence, he said:

“Isn’t that a bit too deliberate?”

"I don't think so. Being young, competitive, unwilling to admit defeat, and a little jealous... is actually normal for me, and it's also a sign of immaturity. What do you think?"

There was no movement from Zheng Xiaofan again.

But Lu Yao did not rush him, but just waited patiently.

After waiting for about half a minute, he said:
"Okay, go ahead. But be brief."

"Don't worry, I can control the size myself."

"Ah."

After getting permission, Lu Yao hung up the phone directly.

After finding Luo Xuewei's WeChat, he thought about it and sent a message directly:
"Is Zhao Lijun from the Eighth Academy of AVIC?"

After sending the message, Luo Xuewei responded more than a minute later:
"? What is the Eighth Institute of AVIC?"

Lu Yao thought to himself, just pretend.

"He is an aerospace engineer? The Eighth Research Institute of AVIC is a research institute under AVIC."

"I don't know much, I just know that he is a researcher like you. What's wrong?"

"Ha, I saw him." "You two ran into each other by chance? What a coincidence?"

"It wasn't a chance encounter. We both attended a meeting together."

"That's quite a coincidence."

"It's quite a coincidence, except that I'm on the stage and he's off the stage."

"I don't quite understand."

"I came to the Eighth Institute of AVIC today to exchange technology with them. I am here as a lecturer, and he... let's just say he is a student, but he still sits in the back row. In front of him are their director, deputy director and other leaders."

Luo Xuewei's reply was a little slow.

"Did you say hello?"

"Their leader did greet me, but he should be just an ordinary researcher, so he is probably not qualified enough."

"Haha, why do I feel like you're a little dissatisfied with him?"

"【roll eyes】"

Lu Yao replied with an emoticon, thinking to himself, you finally took the bait.

Then continue to send:

"It's okay. Apart from the fact that someone turned back on Christmas Eve, I don't have any bad feelings towards him."

"…Please, I went back to the hotel by myself that night."

Lu Yao thought to himself, yes, yes, yes.

"I know, I didn't say anything. [rolling eyes]"

"Ha, are you really jealous? No way, Lu Yao, I'm your girlfriend's best friend."

"[rolling eyes] I know that too. I'm not jealous. I just wanted to let you know that we bumped into each other by chance."

"Haha, yes, yes, you two met by chance. You are on top and he is on the bottom."

"You're a bit dirty."

"My Chinese is not very good."

"[Disdain] Okay, I'm just saying this to you."

"Well, have you eaten? I just got up, and my best friend's boyfriend seems to be a little unhappy with me. If possible, how about letting me treat him to a meal and make amends with him?"

"I haven't eaten yet, but I can't eat with you. I have an internal briefing to attend this afternoon. These soldiers are not qualified to attend, so I guess I will have to stay here all day."

"That night."

"Even at night, I have to work overtime. Another project has also made a research breakthrough. I am so busy."

"...Are you sure you're not using overtime as an excuse to reject me?"

"Of course not. I really have something to do. Let's do it another time."

"Ok."

"Someone is looking for me, so I won't chat anymore."

"Ah."

After finishing the chat with Luo Xuewei, Lu Yao sent their chat history to Zheng Xiaofan.

After reading it, Zheng Xiaofan replied:
"What a scumbag."

"..."

The road is long and speechless.

He didn't reply, and Ms. Zhao asked:
"Did you finish the chat?"

"Well, do you want to take a look?"

"Need not."

The other party shook his head:

"Take a good rest, we're going out first."

"Ok."

……

After a break until noon, the people from the Eighth Hospital arranged for him to go to the cafeteria for lunch. Ms. Zhao and Mr. Qian followed them. They didn't talk about anything about the project, but instead talked about Lu Yao's personal situation.

Top scorer in the college entrance examination, [rock star]...

Of course, the rock star thing is just flattery from people at the dinner table.

After finishing his meal, it was time for lunch and Lu Yao took a short nap in the office. The meeting started at around 2 p.m.

This time, there were only a few people.

Including Ms. Zhao and Mr. Qian, there are a total of 10 people.

This time, Lu Yao didn't need to make any elaborate explanation.

The people from the Eighth Hospital first brought over a few things that he was very familiar with.

chip.

It is square and about the size of two coins.

This is actually quite normal. His model is still in the experimental demonstration stage, and it does not need to be very small. It doesn't matter if it is larger.

And all the data of the chip have also been obtained.

People from the Eighth Institute began to refer to data with him, from simulation data to experimental data, which was as numerous as mountains and seas.

But...the data are highly similar.

What does this mean?
This shows that Lu Yao's model is quite mature, and all kinds of designs can be said to be quite stable... and the most important thing is stability. First of all, the data results of the model design tape-out verified that it can work according to the expected design and all functions are correct.

This alone is enough to surprise everyone.

Of course, this stage of surprise has passed. The fact that they can produce chips today shows that all kinds of tests have been done.

As for the compatibility, which Lu Yao was most concerned about, various data also confirmed that there was no problem.

As for performance, according to Jiang Minglu's original words:
"To be honest, Luyan, the actual performance of this RF chip, including speed, power consumption, stability, etc., far exceeds all of our expectations. It is mature, stable, and reliable..."

While praising him, he looked at Lu Yao as if he were a monster.

I wonder which god from heaven came down to earth to create such a thing.

I haven't heard that there are gods in heaven who are specifically responsible for this.

Of course, after talking about the good things, it is inevitable to start mentioning the shortcomings.

For example, the logic gate problem.

But Lu Yao and they are all well aware of these defects...These are not defects, but they need to be optimized.

Moreover, this kind of optimization...if Lu Yao were to do it himself, he would probably be exhausted to death.

It is a very large project and cannot be handled by one person alone.

And Lu Yao also said this morning that there are still many areas where this model can be optimized.

Everyone understands.

If you want to optimize it further, there are only two points.

One is people, the other is money.

The cost of tape-out is several million. How can a 20-year-old young man pay for it out of his own pocket?

That was a joke.

In short, the internal meeting in the afternoon was more like a briefing specifically for Lu Yao than a briefing.

The purpose is also simple, to inform him that this chip model is feasible.

His data and theories are all on the right track.

As for what to do next...that is not up to Lu Yao to decide.

The project was successful, and his work came to an end for the time being. The next step was to set up a research and development department, allocate special funds, and select talents to tackle the problem.

The original model of this RDSS radio frequency chip has been gradually evolved into what the country needs.

The various devices equipped with it, no matter whether they are swords, spears, missiles, cannons, satellites, lasers...whatever the country needs, the RF chip must meet the requirements.

This is a long-term project and Lu Yao has no say in it.

But his goal has been achieved.

The model is his.

Although the state has the final say on how to tackle scientific research, no one can surpass its position in this model.

He is the absolute core leader of the project.

He is also the father of this "child".

When this chip is released in time, the entire semiconductor academic community will know his name.

And when this epoch-making radio frequency chip is loaded onto rockets, satellites, and even mobile phones and tablets in advance, the name of Beidou will surely resound throughout the universe.

When one prospers, all prosper, and there will be absolutely no loss.

Relying on the photographic memory in his mind... he also wants to see how far he can go in this life!
And what kind of flowers will bloom on this warm land beneath your feet?
