Chapter 105: From zero to one, SOC chip simulation verification completed
“The construction of the R&D building must be accelerated, otherwise there will be no way to accommodate so many scientific researchers.”
Chen Xing reported the information After the technical team was settled, they walked into the elevator and thought to themselves.
With the segmentation and extension of the mobile phone business, Longxing Technology has been involved in chip design, battery improvement and fast charging technology, operating systems, information and communication technology, audio speakers, mobile phone screen assembly research and development, shooting optics, etc. .
Hundreds of scientific researchers are crowded into three five-story experimental buildings with a single floor area of only 700 square meters. This is indeed a bit too crowded.
The headquarters base and R&D building must be constructed and put into use as soon as possible.
“Ding——”
The elevator door on the first floor opened.
Chen Xing was not in a hurry to leave. Instead, he came to several adjacent experimental buildings and wondered who rented them.
While he was wandering around, a security guard seemed to see Chen Xing looking at him with "malicious intent" through the camera. He quickly drove a patrol car close to him and inquired about his identity and said:
"Hello brother, can you show me your pass?"
Chen Xing himself is not very old, and the security guard may be new to the job, so he does not think of Chen Xing as the owner of the lessor.
Facing doubts, Chen Xing also cooperated and took out the pass document and said: "Here, I am the lessor of the three experimental buildings over there."
"Let me take a look."
The security guard took the pass, took the photo and uploaded it to the WeChat group for review. He quickly apologized with a smile: "It turns out to be the president of Longxing Technology, I'm sorry, I'm sorry."
"It's okay. "
Chen Xing took the pass document back and inquired about it: "Just now I wanted to rent these experimental buildings with you, Director Jia. Unexpectedly, they have been rented out. I am more curious about who rents them. Yes, so I came here to look around, which may have caused a misunderstanding."
"That's it."
The security guard suddenly understood and immediately answered for Chen Xing: "This is not a secret. , the laboratory building next to you is rented by Apple, and people have been coming here in succession in the past few days.”
“Apple?”
Chen Xing couldn't help but be stunned.
Apple rents a laboratory building. Do they rent it?
You must know that the main service targets of these rented science and technology parks are small and medium-sized enterprises that cannot afford to build experimental bases.
Apple is obviously not a small or medium-sized company, and there will always be monsters when things go wrong.
But in terms of safety, he doesn't have to worry. The academician's own bodyguard has "truth" on his waist.
Moreover, Chen Xing also arranged for more than a dozen powerful talents to serve as his own security forces for the three experimental buildings.
The triple insurance of SEG Technology Park security, academician guards, and system-strength talents is very safe.
However, I am afraid that Apple has other purposes. If it can be transferred, it still needs to complete the transfer of scientific research personnel as soon as possible.
Thinking of this, Chen Xing wanted to discuss it with the academicians. After a few polite words with the security guard, he walked straight to his chip laboratory.
……
Experimental Building No. 1.
Chip lab on the third floor.
Chen Xing skillfully swiped his ID card to enter. Different from the busy scene he imagined, the laboratory is now particularly "quiet", and all scientific researchers are watching the EDA simulation verification.
He did not disturb this "free time", but from the perspective of a bystander, he was also waiting for the final result to arrive.
Time passes quietly in the morning...
Time passes quietly at noon...
At dusk.
The extremely rare sight of fire clouds in winter dyes the entire blue sky red, dispelling the biting cold wind.
The fiery red light shone through the window into the chip laboratory.
I don’t know how much time has passed, but someone next to Chen Xing murmured to himself: "The baseband partial simulation has passed. The following is the overall running simulation. I hope the power consumption does not exceed 16W this time, otherwise it will need to be reworked and optimized again."< br>
"Has it been optimized many times?"
"It's the ninth time."
"Is it the ninth time?"
The researcher looked away, thinking Who wants to ask this question?
The SOC system-level chip has been optimized nine times. This is the tenth EDA simulation verification. Isn’t it well known to everyone in the laboratory?
He looked sideways...
"General..."
Before he could say anything, Chen Xing made a hissing gesture.
The scientific researcher immediately covered his mouth. After regaining his composure, he lowered his voice and asked, "Why are you, CEO, here?"
"I arranged for the information and communication technology team to come over and take a look. Look.”
While answering, Chen Xing asked: "You just said that the baseband part and other parts of the SOC system-level chip have passed?"
"Yes!"
The researcher clicked He nodded and explained patiently: "CPU, GPU, VPU, I/O controller and other components have been verified to be operational. Now all that remains is the overall simulation."
"I understand."
Chen Xing nodded.
Although he is not an expert in the chip field, he knows that simulation is the final step of design.
If you pass the simulation verification of EDA software, you can take the data file to the chip foundry for trial production.
But the problem now is that TSMC, the world's largest chip foundry, has issued a notice to Chen Xing to stop foundry work in the early morning...
They no longer even make Kaitian baseband chips. , SOC system-level chips, they will not help generation production.
Who can I find for OEM?
Could it be that it is still Loongson International?
Can they really complete SOC system-level chips that are extremely difficult to produce and require demanding photolithography precision?
Taking a step back, even if they can produce OEM, a Qingzhou chip has already frightened Mixi. If the SOC system-level chip is announced, will they go completely crazy and comprehensively restrict Longguo enterprises? ?
"It seems necessary to go to Shanghai to talk to Gao Yongming, the boss of Loongson International."
Chen Xing thought to himself.
As time passed by, it was already seven o'clock in the evening, and the dark night enveloped the deep city.
EDA software simulation has also reached the most important step, post-simulation processing!
This step will conduct waveform viewing, data extraction, and performance evaluation of the simulation results to ensure that the final parameters are qualified.
Gao Zhengqian remained silent and controlled the computer alone.
After the data extraction was completed, all performance evaluations were as expected, and the most important power consumption was fixed at 16W, he breathed a sigh of relief and said: "The data of the SOC system-level chip passed, Bai Yan, you Notify the president to come over for acceptance, and he will select the chip foundry.”
"Finished...done?"
Bai Yan swallowed, and he carefully compared the parameters of the computer.
In the chip laboratory, other scientific researchers, including two academicians, held their breath. They had forgotten that they could breathe, waiting for Bai Yan's confirmation.
"Performance meets standard, power consumption..."
"16W!"
"We succeeded!!!"
Bai Yan's cheers The shout instantly ignited the chip team, which had been silent for most of the day and was extremely nervous.
“Hahaha! Another breakthrough!”
“SOC system-level chip, this time we can officially benchmark Snapdragon chips, Orion chips, and Apple A-series chips!”
“They block, we break through!”
"We are still at the 14nm level, hehe, we are far ahead!"
"Go and inform the president!"
Someone quickly took out his mobile phone and dialed Chen Xing's number.
Unlike other scientific researchers, the two academicians cried with joy. Wang Dezhi burst into tears. He wiped his tears with his right hand and murmured to himself: "With the 14nm SOC system-level chip, we have completed another zero-to-one project." A breakthrough, God bless the Dragon Kingdom, we are not half as smart as Western engineers, we can also make it!"
"From zero to one, haha, from zero to one, hahaha..." and Wang Dezhi burst into tears, describing the different sadness of the chip. Academician Liu Dongsheng not only burst into tears, he also looked at the computer and fell into a giggle, and took out his mobile phone to record:
"Old song we It’s done, are you finished at Longke Academy?”
“Lao Wang is still giving lectures? Our SOC system-level chip design has passed the Loongson EDA software simulation verification!”
< br>“14nm, ten-core micro-architecture SOC system-level chip will make you the fastest in Laohai. Now that the verification is successful, you will not regret it?”
Liu Dongsheng put enough pressure on each of them, and the five people who left early left The moment the academician received the WeChat message, his expression suddenly changed.
......
Imperial Capital, Academy of Dragon Science.
During his time in the Longxing Technology Chip Laboratory, Qu Cheng gained a lot and gained his own insights.
It is no exaggeration to say that he has been completely transformed.
I have my own understanding of chip architecture, circuit design, integration and layout.
If four months ago, his chip design ability was 10, now his ability has reached 15, and many unsolved problems have been explained clearly by Gao Zhengqian.
After completing his studies and returning to Longke Academy, he applied directly to join the Beidou Navigation Project Team without any humility or hesitation, and co-designed the main chip with other academicians.
"Laoqu is great. Now you are too proficient in architecture stacking. At this rate, our Beidou Navigation will be ready for use in less than three years."
"Not only the architecture stacking, but the logic circuits are also done perfectly. Where did you go to learn from it?"
"You disappeared for four months for no reason, and you came back to solve more than a dozen Beidou chip problems. Laoqu, you really Something’s wrong!”
When the academicians praised him, Qu Cheng showed a smile on his face and said mysteriously: "It is true that I went to study. Don't ask about it. I will tell you when the time comes."
Gao Zhengqian and Bai Yan He didn't want to overexpose the two "sweeping monks" for the sake of his own safety.
If Mi Xiangxi knew that there were such "civilian sweeping monks" in the Long Kingdom, he might do something crazy.
Seeing that Qu Cheng was unwilling to say anything, several academicians did not ask further questions. Beidou chip design did not happen overnight. They also planned to get off work and return to Longke Academy tomorrow to continue their struggle.
Just as Qu Cheng was changing back to his regular clothes, his phone suddenly vibrated.
He turned on his phone.
Next second.
"God bless the Dragon Kingdom!"
The sudden words startled the other academicians.
Without giving them time to ask, Qu Cheng immediately said: "I will be away for a few days, and there are unsolvable problems waiting for me to come back."
at the same time.
A classroom at Qinghua University.
Wang Jirong, who already has Mediterranean hair and a cigarette in his hand, is explaining the chip design architecture to his students. This is what he has learned in the past few months.
Except for academicians, few people dare to smoke in class.
And his students are not ordinary students, but a group of semiconductor professors in their thirties and forties from the C9 University Alliance.
Having already talked about the key point, Wang Jirong’s mobile phone on the table suddenly lit up, and the notification bar showed Liu Dongsheng, and there was also a part of the content: SOC chip design...
Although the news was not complete, but Wang Jirong had already guessed what he was going to say.
He didn’t hesitate at all!
He comes gently!
He walked quickly!
Seeing Wang Jirong leaving in a hurry, the professors from the C9 University Alliance were stunned and looked at each other, not knowing what was going on.
I ran away halfway through the lecture!
Qu Cheng, Wang Jirong and other five academicians, when they saw the news, without exception, all booked the fastest flight back to Shenzhen.
SOC system-level chip!
It's coming out!
This is equivalent to a Dragon Kingdom enterprise, which can officially compete with foreign enterprises!
......
In the Longxing Technology Chip Laboratory of SEG Technology Park, a melodious mobile phone ringtone rang. Only then did Gao Zhengqian, Bai Yan and others realize that Chen Xing didn't know something. At that time, we have arrived at the chip lab.
“President!”
“President, when did you arrive?”
Gao Zhengqian hurriedly stepped forward to greet him. Chen Xing looked at his bloodshot eyes and already understood what he had put in during this period.
Want to catch up?
Then pay double the time!
Obviously, Gao Zhengqian and the chip team are spending their time to complete extremely difficult tasks.
Chen Xing was grateful for their efforts, patted Gao Zhengqian on the shoulder and said: "Give yourself a holiday, rest first."
"I will."
Gao Zhengqian nodded.
Bai Yan also hurried forward and said with a smile: "The SOC system-level chip has been successfully verified. This time it can be officially benchmarked against the Snapdragon chip."
"Mr. Chen, this time you You have to think carefully. It is difficult to produce SOC system-level chips. Currently, TSMC may be capable of trial production. "
"Loongson International does not have EUV lithography machines, so it may not be able to produce SOC system-level chips. This time, it is recommended to contact them directly. TSMC.”
Wang Dezhi and Liu Dongsheng also suggested.
Because they participated in the design, they all know how difficult it is to produce.
Currently, among the global chip foundries, TSMC has the best technology and the most advanced photolithography equipment. If they cannot produce it, other companies will not be able to produce it.
"TSMC..."
Chen Xing's eyes flashed dimly.
Gao Zhengqian was keenly aware of this gloom and quickly asked: "What's wrong with TSMC? Could it be that they have been involved..."
"Yes."
Chen Xingdian Nodding, he told the truth about TSMC's imminent discontinuation of OEM baseband chips.
Wang Dezhi frowned and suggested: "It's really unreliable, then look for Loongson International, they might also be able to produce it!"
"Follow the United States to beg for food, I have known about them for a long time. It’s not reliable. It’s okay, Mr. Chen. Loongson International can definitely produce it. After all, they have also produced Qingzhou chips.”
Liu Dongsheng echoed.
Chen Xing also had his own plans. He nodded and responded: "In two days, I will go to Loongson International to talk in person."
As soon as he finished speaking, he glanced at his frowning face and his pupils wrote The worried crowd said: "Ignoring the foundry issue, is there any essential breakthrough in our SOC system-level chip?"
"Yes."
Gao Zhengqian is the chip leader Chief, he naturally explained:
“Our SOC system-level chip is divided into six main functional modules, namely the central processing unit CPU module, the graphics processor GPU, the media processor VPU, and the baseband module, security module and artificial intelligence module. ”
“It integrates the advantages of Qingzhou chip and Kaitian chip and improves it, and the maximum power consumption is reduced to 16W”
“And we have An artificial intelligence module has been added to it. This is an undeveloped module. It can perform deep learning and may be able to compete with Apple’s mobile assistant.”
Mobile artificial intelligence!
Chen Xing’s eyes lit up, this is also the future development trend!
The interconnection of everything in the 5G network is inseparable from the development of artificial intelligence. This module must be well developed.
“Besides!”
Gao Zhengqian changed the subject and continued: “We know that the president is preparing a gaming phone, and the designed SOC chip also has a seventh hidden module function !"
Chen Xing: "What is it?"
"Independent display chip connection!"
Chen Xing was stunned. Okay, isn’t this a function that only computers have?
Gao Zhengqian seemed to see Chen Xing’s doubts and patiently explained: “The seventh main module is also called the connection module. It can connect to the second chip of the motherboard. It can be a game chip or a graphics chip. The chip can even be an Ai chip. ”
“If it’s a gaming phone, we can add an extra gaming chip to focus on performance. The moment the user starts the game, the SOC chip automatically identifies and activates the gaming chip. , to obtain higher game performance”
