Rebirth 1981 starts with saving the sisters from the neighboring village.

The sky in March in Beijing is like a woman's face, it changes at will.

"Ahem~~~The sandstorm in Japan——"

The strong wind blew up dust, making everyone look disgraced.

"Ah, Tui~!"

Only a few days after returning to the capital, Peng Wanhua woke up early in the morning and was choked to the point of breaking his defenses. Sand filled his mouth before he could finish complaining.

I spit out a mouthful of 82-year-old phlegm and finally felt better.

He put on a mask obediently, hurried toward school with his book under his arm.

This kind of mask is a kind of cotton mask, which is very thick. Although it has good dust-proof effect, it is sometimes so stuffy that it can't breathe, and there is still a lot of lint on the mouth.

"This is too backward!"

Peng Wanhua, who couldn't bear it, muttered in his heart and decided to call Wang Debiao to buy a mask factory in Xiangjiang to specialize in improving the production of thin and light masks.

Although the reform and opening up has been going on for several years, the mainland's economic situation is still in its infancy.

Domestic productivity is still very backward, and the advanced technology and equipment needed by mask factories still need to be imported from outside.

Thinking that the economy in Xiangjiang had begun to rebound rapidly, while the economy here was still mired in silence as before, a strong sense of contrast arose in Peng Wanhua's heart.

In classrooms.

Mr. Xu, the head of the electronics department, gave a lecture on the stage.

Because he is old and approachable, everyone likes to call him Lao Xu affectionately.

Even if he gave a lively lecture on integrated circuits, he still couldn't attract everyone.

For example, Peng Wanhua is wandering down there.

"Cough cough!"

Old Xu coughed and glanced at Peng Wanhua.

Seeing that Peng Wanhua finally came to his senses, he gave him a look before continuing to teach.

"Jingle bell~~~"

The school bell rang.

Peng Wanhua was packing up his books and heading out.

Lao Xu took the lesson plan and called him, asking him to follow.

"Wanhua, remember to be proud and complacent when studying. Even though you got full marks in the exam last semester, you still have to pay attention to the lectures this semester, okay?"

Old Xu taught the Tao earnestly.

In the exam last semester, the integrated circuit test questions were very complicated. Peng Wanhua was the only student in the class to get full marks. Lao Xu was very impressed by him.

Peng Wanhua nodded, "What you always teach me is, I will pay attention next time."

"You kid will just say yes. Judging from your scores, you got full marks in most subjects. Is this course very easy for you?"

Seeing that he was perfunctory, Lao Xu obviously didn't take it to heart.

After learning that Peng Wanhua was among the best in other subjects, he knew that he was a talented student.

Suddenly, he remembered a topic he was studying. Let this kid come in and work on it, which can be regarded as giving full play to his talents.

"No, it's mainly because you speak well, Lao Xu, that I can understand and understand you thoroughly."

Peng Wanhua slapped him in the face.

"You guy! That's enough."

Lao Xu smiled and cursed. Although he said enough, he was obviously a little happy in his heart.

He remembered the business and said, "I have a topic in hand. I think you are very talented. Are you interested?"

"The subject?"

Peng Wanhua didn't understand.

"Well, it's about electronic design automation."

As a university teacher, you naturally need to take on research projects, some of which are horizontal and some of which are vertical.

As Lao Xu walked away, he explained to him, "Currently, domestic electronic design is fragmented, irregular, and unsystematic. We applied for the project and planned to take the lead in automation research first.

I will introduce you to your senior brother later, and he will tell you about the subject in detail. In fact, there is nothing much to talk about. Everyone is still crossing the river by feeling the stones, and everything is in its infancy. "

When Peng Wanhua heard this, he immediately remembered that a friend in his previous life was talking about the bitter history of domestic electronic design automation.

The trigger was that a certain company and some universities were included in the entity list by the United States.

The three major foreign EDA giants collectively cut off supply, causing domestic high-end electronic design to suffer a severe blow, even to the point of collapse.

EDA, the full name is electronic design automation, that is, electronic design automation.

In the entire market, the three major foreign EDA giants account for 80% of the entire EDA industry. The interruption of supply by the three major EDA giants basically means that the industrial chain is broken.

Therefore, after the supply cuts, the chip design and manufacturing of domestic major manufacturers, as well as the teaching of universities in high-precision fields, have reached a point of difficulty.

All these consequences are due to the widespread ideological trend in the 90s and [-]s that it is better to buy than to make, as well as deliberate external suppression.

Historically, before the automation of electronic design, the design of integrated circuits was done manually, and each transistor was drawn by engineers one by one.

But by the late 70s and early 80s, with the advancement of manufacturing processes, there were hundreds of device units on a single board, and their design and verification soon became beyond human capabilities.

Therefore, EDA, as the mother of chips, quickly entered the stage of history.

Mentor Graphics, the three major EDA giants, was first established in 1981, and the other two giants, Synopsys and Cadence, were also established subsequently.

The Panda EDA system independently developed in China is also set up at this stage.

This period was very similar to that of later generations, with backward software and hardware technology and attempts to introduce advanced foreign technology for learning.

However, in 1949, the Batumi Committee proposed by the United States and established secretly imposed a technology embargo on our country, and we could only follow the path of independent research and development.

The 80s is actually not too late, after all, foreign countries have just started.

After the seniors worked day and night, in the early 90s, Panda System officially entered the EDA market.

But Panda, which had just entered the market, was immediately pursued by the three major EDA manufacturers.

In business, international giants adopt a very sinister free strategy.

That is, in the EDA system chain, free tools are provided for the strong links of the Panda system, and at the same time, charges are increased for links that are not covered by the Panda system to achieve directional sniping.

In terms of cutting-edge teaching, we make free donations to cultivate the usage habits of the entire industry from colleges and universities, and occupy the minds of users.

This kind of penetration into the upper reaches of the industrial talent supply chain is undoubtedly a ruthless trick to remove wages from the bottom of the cauldron.

In the downstream market, EDA giants have taken control of most IC design and manufacturing plants, resulting in a disconnection of the downstream ecological chain of the Panda system, making it impossible to continuously verify and improve optimization.

Having lost its upstream and downstream ecological support, Panda had no strong internal support and was blocked by international giants from outside. From then on, it gradually collapsed.

In the end, domestic EDA fell into silence completely and could never turn around.

Whenever this matter was mentioned, Peng Wanhua's friend felt very sad.

However, Peng Wanhua is not in that industry and cannot empathize with him. The only thing he can do is to have a few more drinks with him.

Just as Peng Wanhua was thinking about it, Lao Xu pulled him to the door of his office without waiting for him to refuse.

Peng Wanhua smiled bitterly, "Okay, let's go take a look first."

Enter Lao Xu's office.

"Hey, Xiao Dong, I've got a helper for you. Let me meet you. His name is Peng Wanhua."

Lao Xu shouted to a young man inside who was immersed in reading materials.
