Accidentally gave birth to a cute baby

I go to work as usual on Monday, and I have to go to school today. There is a professional exam in the afternoon, and I have to go to the company to apply for a leave.

Just as Xiao Li took the elevator to the parking lot, he met Fu Chuan before he got in the car. He didn't know that Fu Chuan lived in Qu Qian's house opposite him, so he was a little surprised to meet him so early in the morning.

"You, happy birthday."

After leaving this sentence, Fu Chuan went to his own car.

"Thank you."

I don't know if Fu Chuan heard it,

In fact, Xiao Li was still speechless. It's been a day since her birthday, why did she go so early.

A little annoyed, Fu Chuan, as the direct leader, could just ask him for leave to go home, but now that I think about it, it's too late. I just parked the car in the company parking lot and saw Xu Mo, "Brother Xu."

Xu Mo looked over, it was Xiao Li, and now he was waiting for Xiao Li to get off the car, and then saw that Fu Chuan had just parked in the parking lot.

The three of them simply took the elevator upstairs together. In the elevator:

Xiao Li: "Brother Xu, after you went back that day, I realized that the birthday present you gave me was too expensive."

Xu Mo: "Don't say these things are expensive or not. Compared with the feast you cooked with your own hands, it's nothing."

Xiao Li: "Oh, Brother Xu, it's fine for you to come here in the future. Every time it's either for the baby or for me, I'm embarrassed to invite you to my house for dinner."

"Then listen to what you said, I will go empty-handed in the future."

Xu Mo suddenly raised his hand to stroke Xiao Li's head gently and skillfully,

"necessary,"

Xiao Li didn't react much, she was taken aback for a moment and then smiled shyly.

Fu Chuan looked shy in his eyes, because he had an unusual relationship with Xiao Li, he was convinced that Xiao Li had feelings for men, a proper bisexual, a scumbag, Fu Chuan cursed inwardly, extremely upset, every time The first time I saw Xiao Li and her colleagues, no matter if it was the same sex or the opposite sex talking and laughing together, Fu Chuan would feel very uncomfortable and felt that he was scum, let alone seeing him and Xu Mo being so close.

"Ding~" The elevator arrived, Xiao Li and Xu Mo walked out, chatting about their unreasonable Fu Chuan the whole time, Fu Chuan followed behind and didn't speak the whole time, the mood in the morning was just ruined.

Xiao Li successfully asked for leave, one and a half days, this afternoon and tomorrow, so as soon as the lunch break came, Xiao Li went straight to the car and navigated home, and after two hours of rest at home, he navigated the school to take the exam.

Xiao Li didn't know why the exam wasn't scheduled on weekends. It was a bit tiring to run back and forth between three places on weekdays, but after successfully passing several exams, Xiao Li was interviewed by the tutor again.

I still hope that he will continue to study in graduate school.

"Xiao Li, I understand the actual situation of your family. It is understandable that you choose to work for the sake of your children. But from a professional point of view, you are a very talented person. For our profession, you can continue to study further. If you keep going, you will reach a higher height in a few years."

"Now there are two quotas for graduate students to study abroad in October. The time is still very long, but it is also very short. I hope you can think about it carefully. You are the best and most potential student I have ever taken. I don't want you to be stumbled. live."

Xiao Li was indeed attracted, not because of the quota, but because of the affirmation, the affirmation of him.

"Teacher, I..."

"And I can also tell you that there is a kindergarten near the school that non-immigrants can also enroll in, and the procedures are very convenient." The instructor said.

"I believe that foreign early childhood education resources are not much different from domestic ones."

The instructor laughed after he finished speaking, and Xiao Li followed suit.

......

next day

"Xiao Li, you can't see the gap in this data comparison? Are you so perfunctory about your work?"

Fu Chuan threw over an experimental comparative analysis report.

"Xiao Li, what about the performance report I asked you to check? It's procrastinating."

Fu Chuan passed behind and said through gritted teeth.

"Xiao Li, design drawing, how about I ask you to copy the design drawing distributed to everyone?" Xiao Li and Ge Xinning just said a few words in the tea room, and Fu Chuan shouted from the office.

"Xiao Li... Did I ask you to come here as an errand? Have you done the damage and recovery experiment I asked you to test? Why are you still standing here if you haven't done it?" Roared.

In Fu Chuan's office:

"What's your attitude? You still call yourself a chip design engineer?"

Fuck... when did I call myself an engineer?I'm just an intern, okay?

Xiao Li stood straight in the office, cursing silently in her heart:

Did this idiot go out today without taking his medicine?

Is this sand sculpture going to eat too much and go crazy today?

Has this mentally ill person been poached? He kept catching and scolding me.

Xiao Li was really speechless. Last Friday because of An An's illness, Fu Chuan specially sent him home and he was touched for a while. As a result, within a few weeks, he would return to his original inhumane state, and it would become even worse. With human nature, you simply don't treat him as a human being, and you simply don't treat yourself as a human being.

Xiao Li was miserable. She was just praised by her tutor as the best student she ever taught, but now she was scolded by the idiot Fu Chuan and couldn't turn her face in the company, feeling aggrieved and depressed.

Xiaoli University majors in chip design and development, and the team he is intern with is developing a new type of chip—land-vehicle autonomous sensing system.

It sounds ordinary, almost like a tracking navigator.However, it is actually very difficult to do.

Although the autonomous navigation and positioning of flying cars has been realized in this era, the land is different from the air. The independent choice on the ground is too difficult, not only because of the complicated intersection of roads, but also because of the large number of vehicles, autonomous navigation and positioning is too difficult.

What Fuchuan's team needs to do is to independently select the best road section and reserved parking space in the autonomous navigation and positioning, and make the best plan in the shortest time to reduce traffic jams on the road, choose routes, and grab parking spaces. Improve the efficiency of all aspects as the goal of research and development.

As a qualified and excellent chip design engineer like Fu Chuan, in addition to professional single-item knowledge, such as circuits, cost, RTL, heat, durability, quality, performance, and software, cooling methods, algorithms, tools, and simulations are also required. , GPU and other specific computing processors, hardware heterogeneous parallelization and hardware, software recovery capabilities after failure, etc. These aspects of strength.

Qu Lan asked Xiao Li for his opinion when he reported to the company before, because the process of chip design and development is very energy-intensive and labor-intensive. For big projects, she felt that Xiao Li had the ability to participate in the development and design.

Moreover, there was indeed a shortage of talents in this area. At that time, Qu Lan could directly arrange for Xiao Li to join the team, but she still wanted to seek Xiao Li's advice.

Because of her son, Xiao Li replied to Qu Lan on the same day, and then the personnel assigned him to the scientific research department, but I don't know if it was because Qu Lan was unwilling or regretful, and then transferred Xiao Li to the project team as an intern. For Fu Chuan 'like a dog' command.

The research and development and production of chips have lasted for hundreds of years, and the research and development process of chips has not changed much. It is just that the technology is more developed, and there is a better help in terms of material resources and time.

The in-vehicle chip they want to develop was proposed by Fu Chuan. He came up with the design concept and followed up the whole process of design and development. He will follow up and participate in the next steps, including the final mass production and sales.

However, from batch to batch production to sales, it is not known how long it will take to get to this step. R&D is a iterative and time-consuming process of multiple iterations.

A chip is developed, and if problems are found during the continuous testing and verification process, it is necessary to go back to modify the design, and then test and verify again.

During the implementation of the back-end layout, if any of the programs such as area, timing, power consumption, and post-simulation fail, it is necessary to return to the original original design for modification.

Finally, after the chip was released, the test performance indicators and reliability did not meet the design requirements. It was necessary to analyze the positioning problem, repeatedly modify the design, and release the chip again for verification.

and many more...

Seeing is easy to understand, but it is very difficult to actually operate.

The design and development of a new type of chip requires strong strength, manpower, material and financial resources, and requires confidence, patience and a sense of gain or loss.

There are many links in the research and development of chips, large investment, and long cycle. If any details are not considered, or improper errors may lead to the failure of filming.

The technology research and development itself is full of uncertainties, and it is also possible that the filming will fail due to time delays.

Another possibility is that someone else developed it first, so what we have developed is meaningless.

Therefore, the research and development of a mature product requires multiple production verifications. The cycle is longer and longer, and the repeatability of the test is more than one family. It is necessary to seize the opportunity and become the only one.

Therefore, for the chip of the vehicle system, it is not only Fu Chuan who is developing it, but other people are also focusing on it. It just depends on which one has a high timeliness, and the finished product is more convenient and mature to use. For this kind of chip with a high coverage rate In terms of design, the scale is relatively large, the system is also very complex, and the agility and intelligence must be top-notch.

For large-scale production, in order to reduce the risk of casting, the work of system design and test verification is very important. On the one hand, it needs to rely on powerful EDA tools, on the other hand, it needs to rely on excellent professional knowledge, ability, technical experience and personnel time and effort put in.

Xiao Li, who is the only intern in the project team, has a deep understanding of this point. He commutes to and from get off work on time, but the other team members are so busy every day that they are neither human nor ghost.

So when Fu Chuan loses his temper with him, he can bear it as long as he can, and if he can't fight back, he will be as quiet as a chicken and be his intern errand boy.

At present, Fu Chuan’s progress is that they have designed and formed the chip based on the design drawings and the data collected from the vehicle survey, and have entered the stage of simulation testing, and the data has been repeatedly compared and analyzed.

The reason why it is so fast is because this project Fuchuan started to prepare, collect, compose and form a concrete concept when it was in school.

Yes, Fu Chuan is not only the leader of the project team, but also the leader of the chip design concept.

Therefore, after repeated testing and experiments, it is confirmed that it can be put into production. When the chip is developed and molded and transferred to mass production, if the yield of the large product is unstable or lower than the experimental expectation, it is necessary to analyze the reason with the foundry, adjust the process parameters, and then pass it again. After many experiments, the most stable process window was found to improve the reliability and yield of the chip and reduce the cost input.

With the improvement of the world's manufacturing technology level, the cost of manufacturing chips on the production line continues to rise. The cost of an engineering batch production of a 0.3-micron process is 60-80 yuan, and the cost of an engineering batch production of a 0.18-micron process is 100-150-[-] yuan. [-] million yuan, if high-end technology is used, the cost of the test piece will increase geometrically.

If there is a problem in the design, all the chips manufactured in large quantities will be scrapped, causing serious economic losses.

Therefore, in order to reduce the batch input cost, MPW—multi-project wafer will be used in the early experiment, and multiple integrated circuit designs with the same process will be placed on the same wafer for tape-out. After tape-out, each design variety can get several Ten chip samples are sufficient for experiments and tests in the design and development phase.

Xiao Li is new to independent research and development. There is a certain difference between theory and practical operation, but he is constantly striving to improve, but Fu Chuan's attitude makes him doubt his professional ability.

Therefore, amidst Fu Chuan's doubts, Xiao Li silently considered his mentor's suggestion in his heart.
