Technology company, I will become the light of China!

Chapter 71 14nm chip simulation passed!

After Li Zhenzhen heard about Chen Xing, he immediately thought that Longxing Technology would take the high-end mobile phone route.

Mobile phone lenses, screen assemblies, and memory chips are the trend for further high-level cooperation with Korean Star Group.

Chen Xing did not hide anything, nodded and said: "Yes, Longxing X1 has opened up the sinking market. If the second flagship is still in the sinking market, the brand image will be fixed, and the follow-up will be detrimental to the development of the company."

The brand image is fixed, and the most representative company is the rice company.

前世的大米公司连续发布了5款1999元的手机，分别是小米1至小米5，用户都以为小米6手机会继续延续1999元。

As a result, Xiaomi Mi 2499, which was launched at a price of 6 yuan, was widely criticized, with users saying that the era of Rebus is dead.

A low price for once, which is a bonus.

The two low prices may be due to feelings.

Three times, four times, five times, the brand image is basically fixed.

Chen Xing does not want to have a fixed brand image, so for the second new flagship, he must have amazing configurations and cost-effectiveness, as well as technological innovation.

Longxing X1 mobile phone opens the market.

Longxing’s new high-end flagship stabilizes the market.

This is what Chen Xing will do next, and this is the path he must take.

After hearing Chen Xing's explanation, Li Zhenzhen said with a hint of doubt in his tone: "Sometimes your age makes people wonder. Did you start running the company when you were still in your mother's womb?"

Different from the high-end market spreading to the sinking market, Longxing Technology is moving from the sinking market to the high-end market.

These are two business strategies.

As the market spreads downward, sub-brands are generally established.

For example, Rice Company’s Redmi and Kunpeng Company’s Glory have adopted downwardly extending business strategies.

Chen Xing went in the opposite direction, first knocking on the door of the market, increasing his reputation, and then moving up to the high-end market.

Li Zhenzhen has also investigated. Now in the mobile phone market of Long Country, the popularity of Longxing Technology has even far exceeded that of some brands, such as Coolpad, LeTV, Meilan, etc. The Longxing X1 mobile phone is equivalent to the appetizer, and the high-end new flagship is Dinner.

Chen Xing listened to Li Zhenzhen's teasing, smiled and said: "Compared with the eldest princess, I am just a drop in the bucket. Back to the topic, can the lens and memory chips be supplied?"

"No."

Li Zhenzhen decisively refused.

After speaking, she explained calmly: "To supply you with Orion processors, Gaotong CEO Molenkov has come to visit us many times."

"Now if you want to take the high-end route, you must step on Apple's lead. If we provide you with parts supply, I don't need to say more about the forces behind it."

"I can't do anything that would affect the Korean Star Group's reputation by breaking the contract and cutting off the supply."

Her meaning was obvious, she didn't want to get involved in this muddy water.

And from the slight trembling in her eyes, it can be inferred that the Korean Star Group may not be able to offend that behemoth.

Chen Xinggao glanced at Li Zhenzhen. This could be regarded as honest cooperation, notifying possible unstable factors in advance.

Since the financial crisis in 97, most of the Korean Star Group's shares have flowed to Wall Street. As for who is behind Wall Street, there is no need to say more.

However, despite the serious loss of shares in Han Xing Group, the Lee family still controls Han Xing Group through a multiple shareholding structure.

After clearly refusing, Li Zhenzhen added: "If we really want to stop the supply of Orion processors and M series screens, I will do it according to the terms of the contract we signed and send you an email notification one month in advance."

What Chen Xing wanted was this guarantee. He picked up the red wine glass and said with a smile: "I feel relieved after hearing this. With the character of the eldest princess, I believe she will not break the contract."

With one month's notice, even if Han Xing Group really cuts off supply to Longxing Technology Company due to force majeure, such a long preparation time is enough for Chen Xing to find the next company.

"cheers."

"clang--"

Wine glasses collide.

Li Zhenzhen didn't speak anymore, she also had her own plan.

At present, Korean Star Group's chip laboratory has accelerated the research and development of 4G baseband chips. It is unwise to draw a clear line between them before they have their own baseband chips.

Even if the people from Wall Street come, they have no right to interfere with the operation of Han Xing Group. …

After negotiating with Li Zhenzhen to increase the supply contract, Chen Xing was not in a hurry to return to China, but flew to other supplier countries.

At present, Longxing Technology has just started and cannot yet produce all its machines in China. It is important to talk about the supply chain, especially the chip supply chain.

While Chen Xing was flying around the world, the Longxing Technology Chip Laboratory in SEG Technology Park finally came to the simulation verification stage.

Gao Zhengqian looked serious and personally performed the EDA software simulation verification to test whether the 14-nanometer chip circuit was feasible.

Configure simulation tools and establish an environment for simulation verification.

The first step is functional simulation verification.

Use RTL code to perform circuit modeling and simulation, and then execute various test cases by inputting test vectors or test scripts to verify the functionality of the design.

The second step is timing simulation.

Clock signals, timing paths, and signal delays in analog circuits.

This helps ensure that the circuit meets timing requirements when operating properly, including data arriving at its destination at the correct time and timing paths not being violated.

The third step is performance simulation.

This step includes clock frequency, throughput, response latency, cache performance, etc.

Clock frequency refers to the oscillation frequency of the clock signal inside the chip, which determines the speed of the chip's internal operations.

Throughput is the amount of data and is an important part of chip performance.

Response delay and cache performance are also easy to understand, namely delay time and cache.

If these three steps of verification are passed, the fourth step of simulation verification of power supply and power consumption can be carried out.

The power consumption set by Gao Zhengqian for the Qingzhou processor cannot exceed 20W. If it exceeds, it will be rebuilt.

Because it is a ten-core microarchitecture, this is already the biggest concession he has made.

If it goes higher, even a power consumption of 22W may burn the motherboard, which no one wants to see.

Fortunately, after half a month of simulation verification, the first three steps have been passed, and the power consumption of the fourth step has been fixed at 18W, which is 810W lower than the Snapdragon 2 processor.

When the simulation verification and continuous verification were confirmed to be correct, Gao Zhengqian announced with excitement:

"Passed!"

Passed!
Three simple words, sonorous and powerful, as heavy as a thousand pieces!
The seven academicians breathed a sigh of relief with tears in their eyes. Another honor was added to their scientific research career resumes.

[Participate in the design of commercial 14nm processors and Qingzhou chips! ]
"Finally! Is the verification completed?"

Qu Cheng looked excited and had a dreamlike feeling, and the wrinkles on his face had relaxed a bit.

"Yeah oldie! We passed!"

"Hahaha! The 14-nanometer chip has passed the simulation verification. As President Chen said, the boat can cross the Ten Thousand Mountains!"

"I never thought that at the age of 72, I would be able to add another honor!"

"Chief Gao, who can we get the chips from?"

"It's better to find Loongson International as an OEM. I know a few junior engineers there, and they happen to be under pressure."

"Yes, yes! Pressure up!"

The academicians are all talking and are already discussing who to find for the job.

After the chip design is completed and has passed simulation verification, the next step is to find a chip foundry for trial production.

Loongson International?

TSMC?
Korean Star Group?

These three companies can produce chips. Gao Zhengqian did not dare to decide who to choose. He looked at the seven academicians and said:

"Dear academicians, the 14nm chip is of great importance. It is up to the president to decide who the chip foundry chooses."
