Wang Bu'an started the lithography machine.

Various indicators flash methodically. In the end, it all turned into a green light.

This is the lithography machine is ready.

"Don't need to connect the electricity?" Ma Xiangtong felt strange.

"The system comes with its own power. Wang Bu'an disguised and said, "Hydrogen storage alloy unit." It can last for fifty years. ”

"So advanced?"

"Pretty much. ”

Wang Buyan did not elaborate.

Start debugging.

The system shows that the self-test is complete.

The procedure is normal.

The appearance of the lithography machine has a lot of liquid crystal panels. The area of the monomer is more than 100 inches. There's a lot of information shown above.

It is gratifying that the operating system of the lithography machine is actually the core of Linux. After a moment of operation, it feels even a bit like Hongqi Linux, as long as you are familiar with the Linux operating system, if you want to get started, it is still very simple. Of course, if you're using Windows, there's no way to do it.

According to Transformers, they are based on the earth's technological water, reintegrating the operating system. Otherwise, there is no way to use it at all.

The technology is too advanced, and we have to find a way to lower it a little. Otherwise, no matter how good the machine is, it can only be an exhibit.

Ma Xiangtong and others are certainly no strangers to Linux.

He has even led the development of several Linux applications.

The entire operating system, in fact, is fool-proof, at a glance. It's not hard to get started.

Wang Bu'an is now also an expert in Linux.

With his level 100 level of technology, what is a small Linux operation?

Kuang Donghui nodded.

Ma Xiangtong nodded.

They all saw that Wang Buan's operation was simply smooth!

The biggest feature of Linux is instructions.

It's not like Windows, it's mostly done with the mouse.

For those who are familiar with it, Linux instructions are very efficient. However, for those who are not familiar with it, the operation of Linux is a bit more difficult.

Wang Buan's input of instructions was extremely fast.

In just one minute, he had entered hundreds of lines of instructions.

It is estimated that Bill Gates's input speed is not so fast.

The point is, he doesn't need to modify it yet.

The instructions entered are all correct the first time.

If it is from the perspective of a coder, it is simply the ultimate input. Even beyond the limits of the fingers.

The information that Wang Bu'an retrieved was not in the reference manual.

What is displayed on the screen is all deep information.

Including the light source, wavelength, power, wafer type, size, thickness, sensitivity and so on used in the lithography machine.

This information is incomprehensible to anyone other than professionals.

Fortunately, Ma Xiangtong is a professional.

Strictly speaking, lithography machines are more suitable for computer science colleges.

The School of Computer Science is more involved in chip research. Mainly various engineering control chips, microchips, etc. It doesn't have to be the CPU, GPU, etc. of the computer.

In the field of information engineering, it is mainly communication chips. It may not be a mobile phone communication chip.

There are actually a lot of types of chips.

Qualcomm's Snapdragon series, MediaTek, Huawei's Kirin, HiSilicon are all.

In addition to these, there are many other varieties. For example, walkie-talkies, long-wave communications, radio stations, radars, sonars, GPS positioning, Beidou satellite positioning and so on.

The use of silicon materials and integrated circuit boards can be attributed to chips.

"Come on!" Wang Bu'an said.

"I'll come. Ma Xiangtong couldn't wait.

He had been prepared for a long time.

He took out a long-wave communication chip of his own design.

The lithography machine starts reading the data.

Analyze the data.

Organize your data.

Data tiering.

The most critical technology of the lithography machine is data processing.

It has to be a layered design. It is then scanned, branded, spot-inscribed, repaired, and finally soldered in layers, and finally becomes a physical chip.

If this data processing is wrong, then the produced chip is also wrong.

It must come with its own inspection procedure to ensure that the circuit is error-free.

If there is a short circuit, short circuit, breakpoint, etc., it will be questioned and the designer needs to correct it himself.

It's a very long process.

For designers, there are many things that need to be corrected.

No, the chip designed by Ma Xiangtong accidentally put forward more than 100 correction suggestions in less than five minutes.

On the large LCD screen, there is a dense list of correction suggestions, colorful and dazzling.

The red ones are serious mistakes. It is a problem with the circuit and must be corrected.

Orange ones are also more serious mistakes. It must be amended.

The yellow ones must also be corrected.

Green, cyan, and blue are recommended changes. You can do it if you don't change it. However, operational efficiency may be reduced.

The purple message is more special. It is forward-looking.

What is forward-looking? It is looking ahead to the next 20 years.

For example, mobile phones designed in 2000 do not have a WiFi network. Now I suggest you add.

Obviously, in the year 2000, it didn't make sense for mobile phones to join wifi. Because there was no support from the big network at that time. However, you can use this purple suggestion to extrapolate future technological developments.

On the large LCD screen, there is no purple information for the time being.

Maybe the Transformers don't think it's necessary, or maybe the communication chip doesn't work much.

"So many bugs ......"

"So much advice ......"

Old Man Ma's face suddenly became a little ugly.

It's a slap in the face!

A sturdy slap in the face!

I thought it was relatively perfect, but I didn't expect that as soon as I got on the machine, I was checked for so many problems.

Admittedly, not all corrections are the result of mistakes. Part of it may be that the lithography machine can't understand it. Some of them may be the programs that come with the lithography machine, and they "think" that there is a better circuit design. Transformers don't care about you. As long as they feel that there is something that needs to be corrected, all of them will be revealed.

How much has this been checked?

That's less than 1% of the total design!

If this continues, it is estimated that at least a few thousand amendments will have to be proposed.

Wang Bu installed it and did not see it.

He felt that Transformers was a bit too much.

You can't use a level 9999 technology level to demand a level 1 earth civilization!

If it is an ordinary lithography machine, it is impossible to make so many correction suggestions. At most, it is a matter of calibrating the circuit. Then it's time to tape out.

However, Transformers all have obsessive-compulsive disorder.

If they don't think it's good, they have to tear it down and start over. Otherwise, it is tarnishing the test procedure of the lithography machine.

Unconsciously, the circuit design concept of Cybertron Planet has been reflected in various correction proposals. With these correction suggestions, the next time, the chip designed by Ma Xiangtong and them will definitely have an amazing leap in effect. It is even possible to directly reach the world's advanced level. After all, Cybertron's technology is not dry.

It was precisely because he understood this that Wang Buan deliberately pretended not to see it.

After the pain, there is a new life.

He is very much looking forward to Ma Xiangtong's next chip design.

Kuang Donghui looked weird, and he stopped talking.

In the end, Ma Xiangtong sighed silently and stopped the data test.

No way, there are too many mistakes.

In other words, there are too many things that need to be improved.

The lithography machine not only corrected some of the errors, but also made a lot of very reasonable suggestions.

Ma Xiangtong will not shy away from the doctor and will not turn a blind eye.

Since the lithography machine has made so many reasonable suggestions, he must revise it!

Otherwise, even if it is forcibly taped out, the chips produced are useless.

He can't just produce a bunch of junk chips and come out and daydream.

"Xiao Wang, how many generations of lithography machines are this?" Kuang Donghui asked in a low voice.

"The first generation. Wang Buan said cautiously, "The inspection procedure may be a little problematic......

"No problem!" Ma Xiangtong suddenly shook his head and said, "The proposals for lithography machines are all very good. It's because we don't have enough experience in design!"

"Dean Ma......" Wang Buan felt that Ma Xiangtong seemed to have really been hit hard.

Think about it too. Anyway, he is also a well-known expert and scholar in China!

The chip designed by himself has been tested for so many errors, how can you tell him to be indifferent.

If you change to an ordinary person, you will definitely blame the lithography machine for the problem.

However, Ma Xiangtong did not.

He painfully admits that it was his own design that was inadequate.

This is a real expert scholar.

The so-called brick family does not have such a demeanor.

"It's inexperience. Kuang Donghui said in a deep voice, "We don't have enough hardware to do the trial and error. ”

"It's still not our design!" Ma Xiangtong sighed helplessly.

design, they all have a certain foundation.

The biggest weakness is that its own design cannot be successfully taped out.

It is important to know that the process of design is a process of repeated testing and repeated reversal. Design, tape-out, inspection, error finding, correction, redesign, retape-out, re-inspection...... This cycle repeats until the chip produced is qualified and has no fatal flaws.

What the lithography machine has tested is just a simple design problem.

Other usage issues. For example, signal strength, speed, stability, baseband connection, mobile bandwidth, etc., all need to be tested by the actual machine.

What does the actual machine inspection mean?

It is to produce part of the communication chip, install it on the terminal, and then hand it over to the experimenter for use.

Experimenter feedback. Collect comments. Consolidated opinions. Analytical opinions. Then improve it. Then continue to produce, continue to inspect. It is tested until all the data are satisfactory.

For chips, the production process is the process of tape-out - production like an assembly line.

How much does it cost to tape out once?

Hundreds of thousands.

More than millions.

Each design almost has to be torn down and restarted dozens of times, which is equivalent to tens of millions of funds. What a loss.

The country's scientific research funding is always insufficient, how can it withstand such consumption?
