Rebirth: I Carry A Desktop Computer Inside Me - #85 - Chapter 85: The Difficulty Of Modeling Electricity Is As Difficult As Reaching The Sky

As soon as the ACM qualifiers ended, Jiang Cheng also felt relieved.

Although there are powerful plug-ins for the internal computer, we have to admit that there are still many great people in the world.

Even if Li Zhengtao lost, they were still runners-up.

I made the questions entirely based on my own strength.

No wonder those classmates in the class call him “Tao Shen”.

Of course, what Jiang Cheng didn’t know was that after they won the Jinmen Division Championship, they had been dubbed “Jiang God”.

Jiang Cheng returned to Shuimu without rest and continued to start his own chip design business.

Starting from a simple switch circuit, Jiang Cheng progressed from the basic to the more advanced, mastering and understanding the circuit principles of important components such as adders, subtractors, registers, etc.

But when it came to designing a small chip, Jiang Cheng felt the weakness of his own power.

The design of a chip requires design documents and protocol documents at the beginning.

An architect is needed to determine which parts of the protocol can be implemented in software and which parts need to be implemented in hardware.

Then the algorithm engineer has to select the algorithm to achieve the needs based on the needs.

In addition, there must be chip design engineers, described as RTL; chip verification engineers, who perform functional and performance verification on RTL…

Of course, with today’s social division of labor, Jiang Cheng does not need to conquer the world by himself.

After design, there can be a dedicated foundry company that can do foundry and packaging, and a dedicated verification company that can measure performance.

Now, what he is doing is designing a battery charging management chip.

This is a small chip.

But it is also a very useful chip in recent years.

Jiang Cheng chose it after careful consideration.

In the EDA software, Jiang Cheng began to write logic circuit code.

He needs to design a four-switch buck-boost converter.

This is a single-tube non-isolated DC converter in charge management whose output voltage is smaller than the input voltage.

Jiang Cheng needs to make the battery full faster through more reasonable design and low-voltage and high-current charging management.

Yes, Jiang Cheng is now planning to design a flash charging technology similar to “5 minutes of charging, 2 hours of talk time”.

Jiang Cheng thought in his mind.

This advertisement is very good, I want it!

However, this kind of IC chip design and manufacturing is okay, but CPU chip design is not an easy task.

Even if 100 million is invested, it will be difficult to see many bubbles.

As an optical architect, the annual salary starts at 40W.

Not to mention purchasing an ARM architecture license, which starts at several million yuan…

If you plan to develop your own architecture, you must be able to bypass various existing patents, and you will also face the dilemma of no ecosystem in the future.

With the money Jiang Cheng prepared, he only registered Maplefire Semiconductor Co., Ltd.

Even the venue has not been finalized yet.

He plans to use his own internal computer to conduct R&D and design first, and then consider setting up a chip R&D laboratory after it becomes more mature.

Whether it is a mobile phone or a desktop-level CPU, these chips are even more difficult.

Jiang Cheng could only start with simple chips.

The battery charging management chip is Jiang Cheng’s starting design product.

—^_^o~ Work hard! —–

This was Jiang Cheng’s first time to attend a class at the School of Microelectronics.

There were not many courses for his senior year in his major, so Jiang Cheng completed the initial self-study without spending a lot of time.

Now, his focus is on software development and chip design and manufacturing.

One is software and the other is hardware.

In terms of software, Jiang Cheng is currently updating the Maplefire PE special effects production software. He will compile a version and launch it on the market for commercialization (of course, the best version belongs to his own company);

As for the hardware, Jiang Cheng plans to design and manufacture the battery charging management chip.

In the Department of Computer Science, Jiang Cheng has learned a lot of low-level circuit knowledge, but his in-depth understanding of the hardware layer is still not enough.

When he arrived at the Microelectronics Department, Jiang Cheng felt a different kind of boredom.

Analog electronics, digital integration, analog integration, semiconductor devices, semiconductor physics…

It’s all full of useful information.

It makes people’s brains so crowded and swollen.

Fortunately, Jiang Cheng had a computer inside his body.

A deeper understanding of these underlying logic circuits can be achieved.

How to grind a handful of sand into an I9 9900K?

From purification to wafer, from photolithography and etching to packaging and verification.

This series of processes also involves materials, chemistry, physics and many other disciplines.

Modern science is extremely comprehensive and highly divisional.

Can Jiang Cheng alone learn all the knowledge?

Even Jiang Cheng himself sometimes doubts it.

“Classmate, you are not our major, are you?”

Just when Jiang Cheng finished listening and was about to leave.

A man wearing glasses sitting next to him patted his shoulder and asked.

Jiang Cheng said honestly, “I’m a computer person, and I’m here to learn about mold electronics and semiconductor physics.”

“Really,” the man looked suspicious, “You’re not here to chase our girls, are you?”

At a glance, Jiang Cheng saw that although there were more girls than in the computer department, they were still smaller. “No, no, I have a girlfriend.”

“That’s good. We don’t have many girls in our department, so don’t come here to grab resources anymore.” The man warned seriously.

“…”

The man stretched out his hand again, “My name is Wang Xiaogang, do you know me?”

“Jiang Cheng, Department of Computer Science.”

“You are the first one I have seen from your family.” Wang Xiaogang looks good, but his hair is a bit unconventional and long. When speaking, he likes to raise his head to show off his hair.

Jiang Cheng was very modest, “I’m just curious. I don’t know if microelectronics is easy to learn.”

“Brother Jiang, you must get rid of your curiosity.” Wang Xiaogang spoke a little seriously, “I tell you, our major is too complex, such as semiconductor physics and devices, solid state physics, microelectronics technology, etc. Hardware. You have to learn software and you have to learn it. Every day you feel like you are listening to a book from heaven…”

Jiang Cheng nodded to express his understanding.

No wonder you sit so far back.

“Alas! It is difficult to imitate electricity and reach the sky. Integrating or amplifying it, my eyes are so blank…” Wang Dagang shook his head and sang a poem with a look of emotion on his face.

“Well, it shouldn’t be that difficult. I feel like this self-study was pretty good.” Jiang Cheng was speechless and had already made up a song.

Wang Dagang hummed, “The content of this book is one thing, but the title is not that. Young man, you are still young, don’t rely on others.”

“Understood.” Jiang Cheng accepted humbly. It feels like a buyer’s show and a seller’s show!

The two talked for a while, and Jiang Cheng also asked for a lot of information.

For example, which teacher is the most awesome, which course is the most difficult, which direction has the most promise, etc.

After a conversation, the two became more familiar with each other.

“Brother Wang, I want to go to the Institute of Microelectronics. Is there any way?”

Wang Xiaogang hated iron and said very formally, “Your department has such a bright future, so why come to Microelectronics to find trouble?”

…

“It’s not what you think. I want to learn how to design chips.” Jiang Cheng explained.

“Then don’t come here to learn. You’re working on the software side. You just need to understand it roughly.” Wang Xiaogang said, “But if you really want to see it, we have an SRT project we are working on. I can take you in to have a look.”

Jiang Cheng never thought that this was also a big shot, and he felt greatly disrespected.

“What is Brother Wang’s SRT project?”

“Hey, I’m just following the boss to gain experience.” Wang Dagang chuckled and looked at his watch again, “Let’s go, I’ll take you to the research institute to have a look.”

While talking, he pulled Jiang Cheng away.

Jiang Cheng was indeed very interested in the research institute. He followed the boss and quickly entered the institute.

It was different from the very high-tech feeling Jiang Cheng imagined. After entering the institute, it felt similar to the style of most scientific research institute buildings.

And this is an old building, a bit old.

Wang Xiaogang said, “Just follow me for a while. The project side can’t take you in.”

“got it.”

Just as he finished speaking, several men came around the corner.

“Xiao Gang! Why did you bring in irrelevant people again?” The man in the lead asked sternly with a cold look on his face.
