From Almighty Scholar to Chief Scientist

And Lin Xiao smiled again at this time, and said, "Then, I believe you also know about birthday attacks?"

"Yes, I know." Kong Huaan nodded again.

He knows this better, of course he understands this hacking method.

So Lin Xiao just smiled: "That's it, we use the principle of birthday attack to carry out a kind of, uh... feign attack on the logic in the designed integrated circuit, and then use the mathematical principles in the birthday paradox to realize A test of its circuit logic."

"This method can greatly reduce the computing power required for self-inspection and avoid enumerative self-inspection. In addition, our program can also feed back to the intelligence based on the result of the fake attack, and then let the intelligence analyze it. Give an optimization plan."

"In this way, the differentiated functions you are looking for can be realized."

Listening to Lin Xiao's narration, Kong Hua'an showed a vague expression on his face.

It sounded quite powerful, and he also understood what Lin Xiao meant, but he still didn't understand how to describe this logic in mathematical language.

And this probably requires Lin Xiao's mathematical ability to solve it.

However, Lin Xiao saw Kong Huaan's expression, thought for a while, and said, "You should know the role of the birthday paradox in other aspects, right? Redis storage, do you know?"

Hearing the redis storage, Kong Huaan's eyes suddenly lit up, "I know, oh! I know what you mean!"

"Is it like the principle of saving redis storage?"

"Yes." Lin Xiao nodded.

Kong Huaan clapped his hands, showing a surprised expression, and said at the same time, "I understand."

Lin Xiao's idea had to be called bold.

Who would have thought that Lin Xiao would use data attacks to conduct self-inspection and feedback optimization?

But Kong Hua'an is indeed a genius, Lin Xiao just reminded him briefly, and he realized Lin Xiao's plan.

Of course, if Kong Huaan was not a genius, he would not have been able to directly get involved in the field of semiconductors from a programmer, and even play an extremely important role in the X-ray project. After he moved to the field of EDA software, he would directly After writing such a fully functional software, I even planned to innovate.

Lin Xiao smiled and said, "Okay, now that you understand, we can prepare to build this mathematical model now."

"First, let me build the fake attack part."

After speaking, Lin Xiao directly pulled a chair from the side, took the draft paper and pen, and began to write.

When Kong Huaan saw that Lin Xiao started to write, he also found something and started to write, "Then I'll build the smart feedback part later."

"Ah."

Lin Xiao responded without raising her head, and continued to write. Kong Huaan also didn't say much, and started to write.

The part of the fake attack that Lin Xiao is in charge of is obviously the most complicated. It is obviously not easy how to make this fake attack realize the feint attack process while also checking the circuit logic, and achieving the ultimate goal with a small computing power like the birthday attack.

However, this is also something that must be passed. For large-scale integrated circuits, because the circuit is too complicated, it is very troublesome to design. For example, chips with 5nm and 7nm processes can easily have tens of billions of transistors. There is no need to consider transistors. After the circuit is designed, the EDA software can generate transistors according to the circuit. However, the more precise the manufacturing process, the more complicated the circuit will be. Therefore, as long as the function that Kong Huaan wants to design can be realized, it will greatly reduce the number of transistors. Time for chip design.

It can even reduce the number of final tape-outs, and the number of times is the cost.

A 5nm chip tape-out needs nearly 3 million yuan, and four tape-outs, that is more than one billion yuan, and the time it takes is extremely long.

So it is conceivable how useful this function will be, and the major chip design companies will probably be happy with it by then.

And it just so happens that foreign EDA software companies have withdrawn from the domestic market, and the domestic market is blank. Although there is no EDA software in China, if these software can meet the needs, then obviously there is no need to worry about the prohibition of foreign EDA software. .

At that time, once their software with this function appears, the result can be imagined, the domestic market will be occupied by them first, and then there is no need to worry about other things at all.

Thus, the two performed their duties in this way, and at the same time they both entered the state.

Time also passed slowly.

……

The news that the EDA software was restricted quickly spread.

The news that Lin Xiao and the old man got was first-hand information, and then America also announced the news, and after that, related news naturally swept across the country immediately.

Immediately, there was a lot of scolding in the country.

This bald eagle, who thought he had been honest for half a year, ended up showing his original ugly posture, which is really disgusting.

"It's really shameless, except for sanctioning this and sanctioning that all day long, that's all you can do, right? 』

"Can I stop having a bad face? 』

"..."

Among the many scolding comments, some netizens also mentioned Lin Xiao.

『Hey, I said before that I was going to do something about raw materials, but Lin Shen yelled and gave up, and now I’m starting to do something about software. Maybe it’s because Lin Shen didn’t make any achievements on computers before. That's why you have the guts, right? 』

"Lin Shenming also worked on computers. I remember it was two years ago. Didn't there be a hot search saying that several computer Ph. 』

"Yes yes yes, I also remembered this matter, hey, then it's time to sacrifice the forest god"

"Don't get me wrong, Lin Shen's original method of solving problems is strictly mathematical. Of course, I don't think Lin Shen can't use computers."

"Then be the God of Lin, let him punish him, and I choose to sacrifice the God of Lin!" 』

"..."

Many netizens have always had hope for Lin Xiao, as if Lin Xiao has become the anti-Afghan No. 1 in their eyes.

However, among the many external comments, some comments from chip design engineers also appeared.

『I am a chip design engineer. Seeing that there are still so many optimistic voices in the comment area, I just want to say: you know a P!Our company has been using Synopsys EDA software. As a result, our EDA software can no longer be designed. The chip of our original project has been put on hold indefinitely, and the toolkits of each software are different. It is compatible with each other, but the compatibility of domestic software is so poor that it is difficult to achieve compatibility at all. Now all of us are facing the risk of losing our jobs! 』

"I am also a worker in this field. It is really hard for me to imagine what to do. I used to be in this industry, but now I am over 35 years old, and it is too late to change careers. My family still has a mortgage and a car loan, and my son is about to go to high school. , I'm stressed now... alas』

"Me too, now I have to go abroad or go home to farm, but foreign companies don't want people like me, what should I do?"I heard that the chief chip engineer of our company got an invitation letter from Samsung, but our chief chip engineer is considered a bigwig in the industry...』

"I beg the country to help us!" 』

"..."

These comments have gradually attracted people's attention.

It was only then that people realized how much this incident had affected, but even if they felt sympathy for these people, no one could solve it.

I heard that some foreign companies have begun to tap their chip design talents, which makes people realize that this is a series of tricks in foreign countries, not only to draw salaries from the bottom of the pot, but also to take advantage of them.

All of a sudden, the foreign semiconductor design industry began to be in chaos.

……

Warwick Hayes Semiconductor Corporation.

As a company that has designed many chips in Warwick, Hays Semiconductor can be included in the ranks of the world's top chip design companies.

And especially in recent years, Hayes Semiconductor has been on a roller coaster.

First, TSMC refused to accept their orders, and they were frustrated for several years. As a result, they suddenly produced a top-level lithography machine in China, and they also had the ability to produce chips. The Kirin 9000s chip that they recently produced can be said to make them happy. up.

As a result, now, EDA software has been sanctioned, and they are all caught in a dilemma.

Chapter 338 I Don't Believe It—Fuck, I Believe It!

"Mr. Ren, what should we do now? The EDA software can't be used, and we don't know what to do now, unless we use pirated ones, but if we use pirated ones, the foundry will basically not produce them for us."

In the president's office of Hayes Semiconductor, the president Xu Jun is on the phone with their founder Ren Zhengfei.

The EDA software is no longer available. As the president, Xu Jun is definitely facing the most pressure. After all, he is the president who is in charge of so many people in the company, and now their entire company is almost in bankruptcy. Of course he feels Incomparably burnt out.

He even got news that more than half of the chip designers in his company have already received invitations from foreign companies, such as Apple, Intel and other companies, and he feels very powerless about this matter.

Ren Zhengfei, who was on the opposite side, already knew the situation, but he still kept calm and said directly: "Continue designing with pirated software first, and I will think about the problem later."

EDA software is software, so it can be pirated.

However, it is obviously impossible for EDA software manufacturers to sit back and watch their software be pirated, so the update frequency of EDA software will be very frequent. In addition to adding some new functions from time to time, the most important thing is to change various parameters, and then produce The manufacturer reached a cooperation with the chip foundry, so that the EDA software of the chip foundry will always be updated to the latest version, so those chip files designed with pirated software will naturally not be recognized by the foundry's software.

Unless the foundry also uses the same pirated software, however, if it does so, it is easy to be sued. In any case, once the fact of using pirated software is established, it will definitely lose the case in court.

Of course, in any case, using pirated software to design first to ensure the development process is also what they have to do under the current situation.

After Xu Jun heard Ren Zhengfei's instructions, he immediately responded, "Okay, I'll let them use the pirated software first."

"Well, don't be too anxious. There must be a way for the car to reach the mountain, and the boat will naturally go straight when it reaches the bridge. It will always pass."

Ren Zhengfei smiled and comforted him.

"Thank you sir, I understand."

Xu Jun quickly responded, and also sighed in his heart, he really deserves to be Mr. Ren, even at this time he can maintain such calmness.

Then, after hanging up the phone, Xu Jun immediately told the news to their chip designers, and at the same time named Mr. Ren to reassure them for the time being. Next, they can only look forward to their Mr. Ren, a solution can be found.

At the same time, Ren Zhengfei, who was sitting in his office, also put down the phone, but there was no calm look on his face, but he was very distressed.

This matter is very difficult to solve.

There are two ways to solve this problem.

One is to open a company abroad, and these software can naturally be used abroad. However, if their companies really go abroad, then their wealth and life will be in their hands. It is what the other party wants to see.

And the second method is that they develop their own EDA software that can replace those top foreign manufacturers, and this is the right way, but it takes a lot of time, and maybe in the process, their first-class talents will be poached by others If they left, they could be said to be seriously injured.

Therefore, Ren Zhengfei felt very difficult.

But then, he remembered someone.

It was this person who called him suddenly and asked him if he was interested in reproducing the Kirin 9000, and then a miracle happened.

This person is Lin Xiao.

The old man's heart suddenly moved, and then he picked up the phone again and called Lin Xiao again.

Soon, the phone was connected.

Ren Zhengfei smiled and said, "Professor Lin, how are you doing?"

And Lin Xiao's voice came from the opposite side: "It's Mr. Ren, it's been pretty good recently."

"Hehe, that's good, that's good. By the way, our mate40S mobile phone meeting will start soon, and when our Kirin 9000s chip will be officially unveiled, I wonder if Professor Lin is interested in participating?"

"Oh? Then congratulations to you, but I won't go to the press conference, I just wait for your good news."

At this moment, Lin Xiao, who was sitting in Kong Huaan's office, had a smile on his face.

"Haha, that's fine." Ren Zhengfei responded with a smile, and the polite words at the beginning are over, and it's time to get to the point, "Speaking of which, Professor Lin should know about EDA software during this period of time, right?"

"Of course I know that." Lin Xiao said, "It seems that Mr. Ren and you have also encountered problems."

"Alas." Ren Zhengfei sighed, and said, "Of course the problem we have encountered is huge, but no matter what, we must find a way to solve this matter, so I'm here to find Professor Lin, and I want to hear Listen to Professor Lin if there is any way."

"Then you have found the right person." Lin Xiao immediately laughed.

Upon hearing this sentence, Ren Zhengfei was taken aback for a moment, and then his eyes lit up: "Professor Lin has a solution?"

"In a few days, I will send you an EDA software, and then you can experience the functions."

"Okay! That's good!" Ren Zhengfei cheered up.

In fact, after making the call, he regretted it a little, because he suddenly felt that there was no need to bother Lin Xiao about such things.

Lin Xiao is not Doraemon, he can do whatever he wants.

However, the surprise came too fast like a tornado. I didn't hold out any hope, but I actually heard such good news from Lin Xiao.

"Well, that's it."

After Lin Xiao said something, he didn't say any more. After saying goodbye, he hung up the phone.

Then, he turned his gaze back to his eyes again.

In front of him is a computer, and he is currently writing a program.

At the same time, Kong Huaan was sitting next to him, writing a program on another computer.

And the programs they wrote are the differentiated functions they created.

Although Lin Xiao is not a programmer, the speed of writing programs is not slow at all. At the same time, the programs he writes are also very brilliant, and there is almost not much that can be optimized for that kind of optimization.

Even Kong Huaan who was next to him couldn't help being surprised.

Originally, Lin Xiao thought that mathematics should be handled by Lin Xiao, so he came to solve computer problems.

But the ability that Lin Xiao showed now made him feel invincible again.

Of course, he recovered quickly. Lin Xiao was indeed very strong, but he didn't need to lose confidence.

He once dreamed of being a hacker, but now he has become a top hacker, so his ideal has changed, that is to become another Turing.
