Chapter 6 The strong never complain about the environment
The moment Chen Yapeng nodded, Chen Xing officially took over Longxing Technology Company and restarted the chip laboratory.
No chip experiment site?
Then rent it!
Chen Xing took the black card given by Chen Yapeng and rented a five-story laboratory building in Gesai Science and Technology Park, and set up a chip laboratory and a fast charging laboratory.
Gao Zhengqian also understood that his young president was really out of money.
But!
Strong people never complain about the environment!
He only made one request to Chen Xing, which was to replace the domestic Huatian EDA chip design software with the world's top three Cadence chip design software, because the domestic EDA software simply couldn't do the final simulation verification process. .
Chen Xing did not hesitate at all and immediately went to buy the genuine copy as required.
The road must be walked step by step, and the meal must be eaten one bite at a time. He will not demand purely domestic products. The most urgent thing now is to manufacture 4G baseband chips to enable the company to survive the sanctions crisis.
After meeting the most basic conditions, Gao Zhengqian led his chip team to immediately start research and development work.
For self-developed baseband chips, many people will think of photolithography machines and think that only with a photolithography machine can you develop self-developed chips.
But in fact, this statement is not accurate. The lithography machine is responsible for the production process. There is also the design process before chip production. If the chip design cannot be completed, even if you have a lithography machine, you will not be able to create a chip. Chip design requires the use of EDA software.
What is EDA?
Its full name is Electronic Design Automation.
As we all know, a chip has tens of billions of transistors.
Transistors, insulating components and circuits form the most basic logic unit of the chip, and these basic logic units will be stacked layer by layer in a 3D architecture, similar to building a house, to form a complete basic logic unit .
If it is drawn by hand, even if the chip team of 100 people works hard, it may not be able to finish it for thousands of years.
At this time, you need to use the modular design of EDA software. Just like building blocks, reusing circuit parts designed in advance will greatly reduce development costs.
Like Gaotong, they only need to use EDA software to complete chip design and testing. After confirming that there are no problems, the rest is left to the chip foundry to complete.
To put it simply, the chip pie is too big, and no company can achieve a closed loop, so many industries have spawned, such as EDA software companies, chip design companies, and chip foundries.
Three links, no matter which link, you can make a lot of money.
What the chip team is currently doing is chip design. As long as the 4G baseband chip layout can be designed on EDA software and passes the final simulation verification, the foundry can go into large-scale mass production.
Because we are starting from scratch, the first step is to determine the function and performance requirements of the baseband chip, including the supported 4G standards, as well as the data transmission rate and power consumption.
Gao Zhengqian already has preliminary ideas about chip functions and requirements. What he wants to make is a baseband chip that can connect to the entire network.
The current Gaotong 4G baseband chip has not yet achieved full network connectivity. It has launched mobile baseband chips, China Unicom baseband chips and telecom baseband chips for the three major operators in Longguo. This is why the previous There is a reason why 4G mobile phones have customized versions of certain products.
If you want to achieve full network connectivity, you need a more efficient DSP processor.
This is one of the core components of the baseband chip, responsible for performing various digital signal processing tasks, such as data decoding, modulation and demodulation, signal filtering, data compression and decompression, etc. DSP can efficiently execute complex algorithms to Process communication signals.
To summarize briefly, it is the operating brain of the baseband chip.
Half a month.
Gao Zhengqian plans to complete it in half a month.
When the chip team was put into work, Chen Xing discovered another "characteristic" of system talents, that is, they do not need to take a break when necessary, at the cost of losing loyalty.
To put it simply, you can work 24 hours a day, but your loyalty will be crazy. When the loyalty is lower than 60 points, the talent may leave automatically.
However, it is very simple to increase loyalty. There are three ways, namely verbal incentives, salary increase, and paid holidays. Chen Xing also always pays attention to their loyalty and increases their salary appropriately.
……
The other side. Fast charging technology laboratory.
The fast charging team is led by purple talent Yang Bochao. His own scientific research achievement is dual-cell voltage dividing technology.
Compared to the chip team, the fast charging team is making rapid progress.
They redesigned the battery to a dual-cell series design.
According to the principle of series voltage division, the original safe voltage of 5V can be increased to 10V. When a large voltage of 10V is input to the battery, the dual-cell design will divide the 10V voltage into 5V, greatly shortening the charging time.
There are still many technical bottlenecks that the fast charging team needs to overcome, such as battery improvement and power adapter design, which can only be used if they are safe enough.
While the two scientific research teams were catching up day and night, Chen Xing did not take any time off. He waited for the talent market to refresh at midnight every day and recruited useful talents.
Even if it is of white quality, he will not refuse it now.
At the same time.
Kunpeng Company Longgang Headquarters.
Mr. Ren’s face looked haggard and exhausted, and his hair was much grayer, as if a gust of wind could blow him down.
In front of him, a middle-aged man in a white coat with the same haggard face held a document and reported:
“Boss, the 4G baseband chip design is extremely complex, and the amount of engineering work is simply impossible. Imagine that the EDA software we use does not have a similar circuit design module at all. We need to recruit a top baseband chip expert to speed up research and development, otherwise I am afraid..."
"Otherwise what?"
Boss Ren motioned for him to continue.
The middle-aged man hesitated and continued: "Maybe we won't be able to design a 4G baseband chip in a short time."
Mr. Ren was silent.
In 2009, he had a premonition of the importance of baseband chips and invested a lot of money in researching corresponding technologies, but he could never overtake Gaotong.
He knew very well that this chip sanction was aimed at Kunpeng Company.
The purpose is also very simple. First, defeat the leading mobile phone companies in Dragon Kingdom, and then step by step dominate the entire Dragon Kingdom mobile phone market.
Hold on!
They must hold on!
Mr. Ren rarely lit a cigarette, took a deep breath to relieve stress, and then asked: "What type of chip experts are lacking?"
"There is a shortage of all types. We are crossing the river in the dark. We can only use quantity and set up multiple chip teams to develop successfully."
The middle-aged man replied calmly.
Mr. Ren also understood that because there were no 4G baseband chip design experts, he wanted to use the human sea tactic to pile up, which showed that the laboratory was really not optimistic.
If a private enterprise can achieve this level, CEO Ren is not an indecisive person and directly convenes a shareholders' meeting.
In the past night alone, the entire chip field has received notice.
Boss Ren posts hero posts, and talents in the chip field who apply for Kunpeng will be given the maximum salary in the industry.
What is the concept of maximum salary?
In the past, ordinary chip practitioners could be hired for five thousand yuan, but now they directly offer twenty thousand yuan. If it is not enough, they can add more. Who would not be tempted by this?
You must know that the salary of scientific researchers in Longguo is generally not high, because the overall start is relatively late. In order to control costs, companies and research institutes will try to keep the salary of scientific researchers as low as possible, so that many people are living below the food and clothing line. Wandering, waiting for the day when I can make it through.
Now that you are recruiting people with four times the monthly salary, who wouldn’t want to go?
As the saying goes.
Under the heavy reward, there must be a brave man!
Academicians in the field of digital semiconductors also visited Kunpeng Company.
