In 1990, July was in full swing.

At noon, it was like a blazing sun, and it was already sunset.

A touch of colorful clouds on the horizon were dyed into a beautiful sunset under her careful dressing.

Yanjing, Sifang Electron Tube Factory.

The gorgeous scenery outside the window did not distract the young people who were struggling to write on the desk.

"Jingle bells, jingle bells......"

On the cluttered desk, a landline phone that had been squeezed into the corner of the desk rang again.

This is already the third time it has sounded.

Yu Zixian is checking the just-written "Some Supplementary Suggestions on the Future Development of Sifang Electron Tube Factory".

Listening to the phone ringing again, he frowned and hesitated to answer the call.

He was in a hurry to carry out the final sorting of the chip information of the TV movement, and the time would be relatively tight.

After thinking about it, Yu Zixian still picked up the phone: "Hey, ......" But before he could finish speaking, there was a loud shout in his ears.

Zhang Haitao's sharp and slightly hoarse voice came from the microphone, and every word he said on the other side was like puncturing a balloon.

On the other side of the microphone, Yu Zixian is the person he usually doesn't want to deal with, but the other party is in charge of the personnel in the factory, and some things really can't get around him, otherwise Yu Zixian would have put down the phone in his hand a long time ago.

Now, he had no choice but to move the microphone to one side, keeping the sound as far away from his ears as possible and drifting to the other side.

Even so, the voice in the microphone was quite strong, violently shaking the air, and a series of cannons along the telephone line, and finally exploded out of the earpiece:

"Yu Zixian, do you know what discipline is? Sifang Factory is not your home, you can resign if you want to? Do you still want your files? You are a stinky boy who has just entered the factory for a few days, and you have been ......pointing fingers at the factory for a few days."

Hearing this, Yu Zixian really wanted to say, "You are also a leader of a big factory, how can you lower your identity and put yourself in the position of a shrew who is a shrew?"

Yu Zixian thought about it for a while, but hung up the phone in a hurry.

He really couldn't figure it out, didn't he just hand in a resignation report, and by the way, he wrote some letters of advice related to the development of the factory, why did the other party become like this?

It's unreasonable!

Originally, he thought that the old man had a conflict with him in the past, but it was a matter of work, a matter of their older generation, and it should not be put on himself or such trivial matters as resigning.

But looking at the current situation, it seems that he has overestimated this person's heart. used "calculating" to describe him, Yu Zixian felt that he was praising him.

It's a pity that my old man has been retired for a few years, otherwise the other party wouldn't have intensified like this!

Perhaps it was because he hated people like Zhang Haitao in the factory that Yu Zixian was even more determined to leave here.

Originally, he was still hesitating, but tomorrow, will he leave or stick to it?

Now that it's okay, Zhang Haitao used practical actions to help Yu Zixian make this decision happily.

Yu Zixian believes that even if he leaves here, even if he is not vigorous in this life, it is destined to be like the sunset on the horizon, gorgeous and colorful; sticking to this place, staying in the Sifang Electronics Factory, which is still a rigid system, even if he is a person who has come over, he will definitely be restrained, and in the end it may only be a waste of his few years.

Quartet is saved, but he is still waiting for her real helmsman, and he knows that he is not that person.

In the future, the center of gravity of China's economic map is in the vast south, and that is a good place for him to show his strength!

Speculating in real estate, land, stocks, and finance, perhaps this is his best choice. Being a local tyrant in the future is the life he yearns for: sleeping until he wakes up naturally, counting money until his hands cramp, and walking to the peak of life is not a dream......

It is easy to do things if you have money, and everything is off if you don't have money, this truth is applicable from individuals to factories, from society to countries.

Just like the Sifang Electron Tube Factory, a huge factory, because it has no money, it actually relies on Yu Zixian and a few other people to imitate other people's "chips" to optimize their own products.

It's okay to do this in the first place, but can people send more? Can the equipment be better? Can the software be updated?

And the reality is so cruel: there are less than ten people, two rookie college graduates with a few old, weak, sick and disabled; TV movement production line equipment,It is a third-hand product introduced a few years ago;The color TV CAD used to optimize the design is the first generation of domestic software developed in 83 (TADS-C1),Used to design and optimize the existing movement chip circuit,But the heart is more than enough but the strength is insufficient!

Yu Zixian carefully checked the document bag containing the two documents, sealed it, and looked at the messy clutter on the table...... The heart is also messy.

The microscope on the table was borrowed from Liu Jian, and under the lens was a chip that he had removed from Toshiba's latest television.

The TV set was bought back by Yu Zixian and Liu Jian with half a year's salary each.

The two computer chips were taken by Yu Zixian, and the rest of the movement board was taken away by Liu Jian and them to study, while the TV case shrank in the corner, trembling, as if he was still afraid of Yu Zixian's violent dismantling.

One of the core chips on the TV movement lies under the microscope.

The circuit design of the TA two-chip microcomputer composed of TA7680AP and TA7698 chips was developed and designed by Toshiba in 1983, but the TA two-chip microcomputer still has considerable advantages compared with the current domestic mainstream four-chip and three-chip microcomputers, whether it is the cost or the function of the TV, it is still proud of domestic production.

Liu Jian, a good friend of Yu Zixian, works in the TV supporting factory of the third branch of the Sifang Electron Tube Factory, and is responsible for some technical management in the workshop. Since Yu Zixian graduated from microelectronics, since he went to work, Liu Jian often came to discuss the design and optimization of TV circuits.

Although Yu Zixian does not work in the third factory, he also wants to do his part. I want to turn the production line of the third branch factory that has been stopped for half a year as soon as possible, help Sifang Electron Tube Factory get out of the quagmire of loss as soon as possible, and finally realize the industrial transformation of this old factory.

Although in his opinion, it is very difficult for the third branch to rely on the strength of a few people to optimize the circuit of the four-chip microcomputer, because they do not even have the domestic second-generation color TV CAD software (TADS-C2).

In fact, the third branch factory wanted this system very much, but she didn't have the money.

The key is that now not only the third branch factory has no money, but the entire Sifang Electron Tube Factory is short of money.

In recent years, Sifang Electron Tube Factory has lost money every year, and it is strange to have money!

There is also a reason why the supporting workshop of the third branch is eager to optimize the movement they produce, and the movement they produce is a four-piece machine, which is a product that is about to be phased out.

The function of the TV is realized by the various circuits on the movement, each with its own function, for some main circuits, chips are also needed to achieve control and task execution, such as the core Toshiba TA two-chip microcomputer, of which TA7680 is responsible for completing the image intermediate frequency and sound small signal processing, TA7698 completes the brightness and scanning small signal processing, and the switching circuit uses a thick film circuit, and other sound amplifier field output, line output has discrete component circuits......

Generally, the higher the degree of integration, the fewer chips used, the fewer unit circuits on the movement, and the smaller the volume of the movement, and then the less the production process, the production cost of the TV will be reduced accordingly.

In the past, when TVs were sought-after goods,There will still be a market for color TVs with a four-piece machine movement like this,But with the price war of TVs in the past six months,The price of TVs has dropped sharply,This kind of four-chip color TV with backward performance but high cost and high price is suddenly facing a situation of losing money and making money、The production line is forced to stop production。

This is also the reason why Yu Zixian and Liu Jian had to devote all their energy to "copying" the core chip of Toshiba's TA two-chip machine, and then optimize their four-chip movement.

The movement is the core of the TV, and the chip is the core of the design of the movement.

At this moment, the two chips that Yu Zixian got at a great cost and are usually regarded as treasures look really miserable: the front of the chip has been removed from the packaging protective shell, revealing the tiny internal circuits inside.

This is to better study the inside of the chip, analyze its functions, and prepare for the reverse design of the chip.

International design companies are basically based on forward design, and reverse design is only used to check whether other companies have plagiarized. Of course, the original purpose of chip reverse engineering was also to prevent chips from being copied, but it has since evolved into a solution adopted by small companies in order to design chips faster and more cost-effectively.

For companies that are in the early stage of development, they are basically reversed, supplemented by positive.

And what Yu Zixian is doing now is equivalent to layout extraction in reverse design.

Of course, these internal circuit layouts are not visible to the naked eye, but they can be observed with the help of a microscope and published diagrams, and finally converted into internal circuits.

Yu Zixian has already tried to find some reference circuits and external characteristics of the chip, but if you want to optimize, you also need to understand the topology and component parameters of its internal circuits in detail......

Fortunately, after nearly half a year of busyness, Yu Zixian finally completed the last bit of work today, that is, to complete the shooting of the chip layout and the conversion of the layout to the circuit, and the subsequent task is to conduct a careful logical analysis of these circuits.

TA two-chip microcomputer was designed 7 years ago in 83 years, using a 5-micron process level, and there are more than 2,000 transistors inside the chip, and the circuit is relatively simple. This is also the reason why Yu Zixian can imitate the territory.

In a few years, when the era of large-scale integrated circuit applications arrives in an all-round way, and there are millions, or even tens of millions, or more than 100 million transistors on a chip, this kind of imitation can only be stared at.

At that time, it is the design ability and manufacturing capacity of the chip that will be spelled, and further speaking, the ability to fight for design software and design talents, manufacturing process threads, and chip manufacturing equipment.

We have these advanced things, even ten years ago. However, four or five years ago, there was a gap of four or five years, two or three generations, between us and the international advanced level, but now, the gap between us is even greater, reaching more than 10 years. Since then, our technology has not caught up, not in 10 years, and still not in 20 years.

Under the influence of the "Batumi" embargo and the subsequent "Wassenaar Agreement", under the technological blockade and patent blockade of the international integrated circuit industry giants, it is actually very difficult for us to break through these shackles by our own strength.

Anyway, 20 years later, with the country's large capital investment and vigorous introduction of talents, our industrial chain has made a breakthrough in one direction, that is, the etching machine in chip manufacturing equipment......

It's a bit far to think about for a while, but it also shows the embarrassing situation that we in the electronics industry are facing at this moment and in the future.

After sorting out the layout data of the two chips, Yu Zixian carefully checked the "Supplementary Suggestions" again.

Yu Zixian had submitted a "Development Proposal" to the factory before, but this "Supplementary Proposal" is more perfect.

"It is necessary to completely break the big pot rice system, give branches or subsidiaries greater operational autonomy, effectively improve the treatment of technical personnel, increase technology research and development costs, attach importance to and respect the market, and product development should be market-oriented......"

Everyone is leaving, so naturally there are a lot less scruples, what else can't be said? Anyway, everything Yu Zixian can think of has been written.

"Knock knock......" Suddenly there was a sharp knock on the door.

Yu Zixian is still lost in his thoughts......

"Bang, bang......" The knock on the door became more and more urgent.
