Technology company, I will become the light of China!

Chapter 41 Non-Commercial EDA Software
Ten cores?

Chen Xing was stunned for a moment. The first thing he thought of was not the performance, but how to solve the problem of chip heat dissipation.

Throughout the development of mobile phone processors in the past generations, from single-core and single-thread to today's four-core and eight-core processors, the performance has improved, but the temperature has also increased.

For example, the Snapdragon 810 processor released not long ago. If Chen Xing remembers correctly, it was known as the "Fire" dragon chip in its previous life, and its operating power consumption was almost 20W!

What concept?
2022年上市的骁龙8gen2也才12W功耗，而骁龙810却足足有20W，搭载它的手机最直接的感受就是烫手！
Now Bai Yan actually wants to build a ten-core chip. How much power will this consume?
Gao Zhengqian became interested and tried to analyze: "The performance of the ten-core chip microarchitecture has been improved, but the increase in the number of cores means that the power consumption also increases, and the heat also increases. The mobile phone cooling system of Longxing X1 I'm afraid that the temperature of the processor cannot be suppressed, maybe you have already thought of a solution?"

"The heat dissipation is not my responsibility. The president must have a solution."

Bai Yan spread his hands and looked at Chen Xingdao with a smile.

He is only responsible for the chip architecture design. Whether it can control the temperature and whether it will burn the motherboard has to be solved by Chen Xing.

Gao Zhengqian's eyes couldn't help but twitch, and he shook his head and said: "Ten-cores have the risk of overheating, and eight-core technology is more mature."

After thinking for a while, Chen Xing did not dwell on the number of cores, but instead focused on nanotechnology and said: "Let's put the micro-architecture first. At present, Gaotong Company has mass-produced 20-nanometer chips. If conditions permit, I think we can also To keep up with them or even surpass them.”

"That's simple. We make 14nm process chips, but before that, well, the EDA software problem must be solved first."

Gao Zhengqian responded calmly.

Bai Yan: "Add a 10-core microarchitecture!"

"I can't control the temperature!"

"If you can suppress it, you can suppress it. The president must have a way to suppress it. I still have a 12-core chip microarchitecture."

"What should I do if I can't hold it back?"

"The president will find a way!"

While the two were still arguing about micro-architecture, Chen Xing was sizing up Gao Zhengqian. He found that he still underestimated red-quality talents.

The sentence "That's easy, we make 14nm process chips" made Chen Xing a little confused as to where his limit was.

Maybe 7nm.

Maybe 3nm.

Or 1 nanometer...

When he came back to his senses, Chen Xing looked at the two people who were still arguing about the number of cores and made a suggestion: "Design eight cores first, then ten cores. I will find a way to solve the heat dissipation issue."

It’s not that he doesn’t have cooling talents, it’s just that they are all blue quality and he hasn’t set up a dedicated mobile phone cooling system laboratory.

As for the cooling of mobile phones, he himself has some ideas.

You can refer to the previous White Shark mobile phone and install an air-cooler directly into the mobile phone. However, in that case, battery power consumption will be a problem, and the internal layout of the mobile phone will also need to be redesigned.

Chen Xing didn't think much about it. He planned to visit Huatian EDA Company first and ask if there was a more advanced internal beta version of EDA software before making any plans.

Once the EDA software problem is solved, projects for 10 cores, let alone 20 cores, are allowed. Whether the temperature can be controlled and whether the motherboard will be burned are not things that need to be considered now.

Quickly solving EDA software problems is the top priority.

……

In the next two days, he simply packed his luggage, explained the company's affairs, and flew directly to the headquarters of Huatian EDA Company in the Imperial Capital.

The boss of Huatian EDA had already anticipated Chen Xing's visit.

Paper cannot cover the fire, especially since it is an EDA software company.

However, no one in the industry expected that the three giants of EDA software would once again take action, but they would only target a small company that was not listed on the market. This was no less than killing a chicken with a bull's knives, using anti-aircraft guns to kill mosquitoes, and leaving no room for sanctions.

Ten years ago, the three EDA software giants sanctioned Longguo EDA Software Company and adopted a free strategy.

Many domestic EDA companies have declared bankruptcy before making a profit. Although Huatian EDA is not bankrupt, it has plummeted and fallen out of the world's advanced ranks.

And now, ten years later, they are back again.

This time, the sanctions were not imposed on EDA software companies, but on mobile phone technology companies. This also made many people angry. It is a common Western tactic to impose sanctions on domestic companies if they have scientific research results.

"Mr. Chen, I have long admired your name!"

The boss of Huatian EDA is called Liu Wei. He is 44 years old this year. He has an 80s Hong Kong-style side bangs hairstyle. He has a loyal appearance and his figure has become slightly out of shape with age.

"Although this is the first time we have met, I have heard of Mr. Liu's reputation more than ten years ago." Chen Xing praised him with a smile while shaking hands with him. "More than ten years ago is too long to be mentioned at all, but Mr. Chen is a rising star in the current technology circle. The Kaitian baseband chip and Star Flash fast charging are really easy to use. You see, my mobile phone is It’s Longxing X1, I’ve always wanted to make you a friend.”

"Let's stop talking standing around. Come on, come on. Sit down first. I'll give you a taste of the tea I've treasured for more than ten years."

Liu Wei greeted him warmly, took out a cake of old tea leaves from the drawer, and began to make tea.

Faced with such warm hospitality, Chen Xing did not rush to talk. Instead, he tasted the tea first. After the two got acquainted briefly, they chatted for another half an hour before gradually getting down to business.

"Mr. Liu must have heard that Gaotong Company has teamed up with the three EDA software giants Synopsys, Cadence and Mentor to impose sanctions and blockade on our company. I came to visit your company this time just to ask Mr. Liu if there is a more advanced EDA software version. .”

Seeing Chen Xing getting straight to the point, Liu Wei stopped beating around the bush and said bluntly: "Then let me speak openly. We do have a more advanced and accurate Huatian EDA3.0 version."

"Compared with those three companies, how is the performance and simulation verification?"

Chen Xing's eyes lit up and he said.

If domestic EDA software is comparable to the software of the three EDA giants, then the sanctions will be defeated this time.

The chip team can also work day and night to concentrate on developing processor chips.

"Ugh!"

Liu Wei couldn't help but sigh, his eyes dimmed a bit, and he shook his head and said: "There is still a natural chasm between us. I can only guarantee an 85% verification accuracy."

Don't look at 85%, even if there is only a 1% difference, the foundry may pay tens of millions in trial production.

"but!"

Suddenly, he changed the subject.

If other companies were to ask, or if Longxing Technology Company had not been sanctioned, Liu Wei would not tell this industry secret, but what Longxing Technology is experiencing now is very similar to the situation when they were sanctioned ten years ago. .

They also achieved leading results, were also sanctioned by patent troll companies, and were equally desperate.

If it had not been sanctioned, there would not be three but four EDA software companies in the world. Huatian EDA is definitely among them, and it is first-class.

Having been exposed to rain himself, Liu Wei can sympathize with Chen Xing, and he is also willing to guide the direction of Longxing Technology.

Chen Xing regained hope and seemed to have seen a turning point: "But what?"

"I'm only telling you this, but please don't spread it."

"I promise!"

Chen Xing looked serious and made a promise.

Liu Wei also wanted to believe in Chen Xing's character and lowered his voice and said:

"Although the commercial domestic EDA software on the market is not as good as those three companies, we in Longguo also have non-commercial EDA software. You should have heard of Zhongke Loongson. They have dedicated EDA software in-house, and the accuracy is estimated to be More than 95%, maybe you can use your connections to see if you can borrow it.”

"Zhongke Loongson..."

Chen Xing murmured to himself.

From what Liu Wei meant, he wanted him to go to the Academy of Dragon Science!

But he doesn't know any academician of the Long Academy of Sciences, and he borrows the internal EDA software. Isn't this too difficult?
Seeing Chen Xing fall silent, Liu Wei seemed to have guessed something, and pointed the direction again: "The boss of Kunpeng Company may be able to help you."

The CEO of Kunpeng Company, isn’t that Ren Guofei?

But it is true that with Ren Guofei's personal connections and having been rooted in the Dragon Kingdom for decades, it is not surprising that he knows several academicians of the Academy of Dragon Science.

Chen Xing silently wrote down the key information and thanked him repeatedly: "Thank you, Mr. Liu, for informing me. This information is so crucial."

"You're welcome, ally."

Liu Wei smiled.

When he was jointly sanctioned by the three EDA software giants, the company plummeted, and he had long hated them.

If Longxing Technology can survive the desperate situation this time, it will be a slap in the face for him from the bosses of the three EDA software companies.

Because he himself had been caught in the rain and experienced the despair of being punished, he also wanted to hold an umbrella for his younger generations.

　Thanks to Ban Duoqiangwei and Yanjiu Yanluo for their monthly votes, and to the big guys who follow me, there will still be three updates today, in the afternoon and evening.
