1991 Starting from the core

The computer room was quiet for a few seconds.

The draftsmen who were operating computers all around turned around, wanting to see who was so awesome that he could complete a tape recorder layout in three hours.

When they saw that the person who said this was too young, perhaps even less than 20 years old, these draftsmen just smiled and turned around to continue working.

As for the Pan Dajun brothers, they just glanced at Su Yuanshan - to talk nonsense to such extent is not arrogance, but madness.

It seems that this telecore technology from a mainland province was still living a few decades ago, and the habit of launching satellites has not changed yet.

At this moment, Pan Dajun even felt a deep sense of sadness - it is said that Yuanxin Technology was opened by a professor from the University of Electronic Science and Technology of China. Even the professor is like this, so how can domestic technology develop? What are you comparing yourself to? Do you scare people to death by bragging?

…

When Wang Chaoxin heard this big talk, his first reaction was that Su Yuanshan had gone too far with his words. However, when he saw that Tian Yaoming and Qin Weimin only lowered their heads and took a closer look at the drawings after hearing Su Yuanshan's words, they actually clicked in the end. When he nodded...he was slightly startled, and his eyes sparkled.

When Yuanxin Technology took the letter of introduction from Dianke and asked Jiangyin Factory for cooperation through Jiang Qingchuan, Chaoxin was having a meeting in Beijing. Of course Chaoxin would not miss this opportunity to cooperate with high-tech companies, so he agreed without saying anything. I also went out of my way to understand Yuanxin’s technological capabilities. However, he failed to do so because this was a purely private enterprise that had not been registered with the state and had not received state support.

This aroused Wang Chaoyang's new interest. Later, when he accidentally mentioned this matter at his brother-in-law's house, his nephew who was studying at T University gave him the news, saying that Yuan Xin was very powerful - because his nephew had classmates. I joined that company to do program development.

Therefore, when Wang Chaoxin returned to the factory, he was very polite to Qin Weimin and others and cooperated very well. And after contacting him, he also confirmed that Qin Weimin had a master's degree, which was not comparable to some parallel imports.

So... their software is really so efficient?

Wang Chaoxin took a deep look at Su Yuanshan, looked at Qin Weimin and asked, "Brother Weimin, is three hours really okay?"

Qin Weimin also glanced at Su Yuanshan, smiled meaningfully, and nodded: "Of course it depends on your computer configuration. The company usually uses multi-CPU workstations for testing, which are much faster."

"Then please help me!" Zhang Jianjun stepped forward and held Qin Weimin's hand as if he had grasped a life-saving straw: "What do you call me?"

"Qin is for the people."

Jiang Qingchuan on the side smiled and added: "He is my senior brother, Master Qin Weimin."

"Anyway, he is a top student!" Zhang Jianjun shook Qin Weimin's hand excitedly: "Help, Master Qin, we are really waiting impatiently."

Seeing this, Wang Chaoxin squinted his eyes and turned to Pan Dajun: "Director of Dajun, let them try."

Pan Dajun's face darkened, and before he could speak, his brother Pan Xiaojun finally couldn't bear it any longer. He stood up from the computer and walked towards Qin Weimin in a few steps.

"Master Qin from the Department of Electrical Engineering, right?"

Qin Weimin nodded and said lightly: "What do you call me?"

"Pan Xiaojun, a technical secondary school student, is not as good as Master Qin." Pan Xiaojun put his hands in his pockets, raised the corners of his mouth slightly, and did not hide his disdain: "Although I am not capable of developing EDA, I have seen and tried foreign EDA. I have also used Panda CAD, which has been in China for several years."

"I admire your Don Quixote-like courage, but can you please stop wasting national resources?"

Qin Weimin is very well-educated. Even if he is compared to Don Quixote, he is not angry at all. He continues to smile lightly and says: "Why do you think we are just fooling around?"

"Hi!" Pan Xiaojun smiled, ignored Qin Weimin, and turned to Wang Chaoxin: "Director Wang, I heard that Cadence is going to open an office in China next year. You will know what real foreigners mean if you get in touch with them. programmer!"

Finally, Pan Xiaojun looked back at Qin Weimin with a hint of ridicule on his face: "We are all engaged in technology. I don't know what domestic software development is like?"

At this time, a calm voice sounded.

"Are you worthy of being called a technician?"

Pan Xiaojun's eyes froze, and he immediately turned to stare at Su Yuanshan.

Su Yuanshan crossed his arms, the smile that always hung on his face disappeared, and he became extremely calm.

"Say it again!"

"I said you don't deserve to call yourself a technician." Su Yuanshan frowned slightly. Seeing that this man seemed to want to take action, he took a step back and said calmly: "Technology is used to solve problems. If the program crashes, the first thought It should be that a bug occurs during the programming and compilation process, then the bug should be found and solved. Instead of asking people not to do this or that."

"The software you bought is for use, not for the Bodhisattva you invited back."

"You don't even have the courage to face the problem directly, and you still dare to talk about being a technical person?" Su Yuanshan stared at Pan Xiaojun: "If I were you, I would be embarrassed to say it."

"you……"

"Not convinced? If not convinced, just watch it honestly." After saying this, Su Yuanshan ignored Pan Xiaojun, strode towards the computer, exited the system, and turned off the power.

At this time, Pan Dajun finally couldn't help but stepped forward and shouted: "What are you doing? Who told you to move?"

Wang Chaoxin's face darkened: "Director of the Army Factory! Let them try!"

As he spoke, Wang Chaoxin looked at Qin Weimin: "Weimin, are you coming or Dr. Tian?"

Su Yuanshan didn't look back: "You don't need a machete to kill a chicken, I will do it."

…

After installing the hard drive and mouse that came with it, and loading the driver, Su Yuanshan started Yuanxin EDA.

Looking up at the hand-drawn circuit diagram hanging on the wall, Su Yuanshan moved his mouse quickly, dragging components one by one to the engineering interface.

The single-layer PCB of the radio cassette player is indeed a killing blow for Yuanxin EDA, which focuses on multi-layer PCB and large-scale integrated circuits.

In less than an hour, Su Yuanshan completed the placement of all components. Over the next hour, he began arranging the location of components and adjusting wiring.

When all the solder joints and circuit diagrams are completed, there is still half an hour left.

The people behind him were stunned, especially the draftsmen who were still struggling to draw. They had never seen such a puzzle-like drawing method, nor had they ever seen such an intelligent wiring method - —Those lines seemed to be spiritual, easily choosing the best path along the position of the first copper foil line, perfectly avoiding all solder joints and pins.

"It seems there's still time left." Su Yuanshan looked back at Factory Director Zhang Jianjun, who was holding his breath and looking excited. He thought for a moment and said, "Can I see your appearance and mold drawings?"

"Ok, Ok!"

Although he didn't know what Su Yuanshan wanted to do when he looked at the mold drawings, Zhang Jianjun took out the mold drawings from his briefcase and handed them to Su Yuanshan.

Su Yuanshan looked at the mold drawing and found that the cassette recorder still followed the old antique design, and continued to ask: "The mold hasn't been opened yet, right?"

"No, I'm waiting for the board. I won't dare to open the mold if the board is not ready."

You really don’t dare to open the mold if the board is not ready, because the size and structure of the board may be temporarily adjusted. Opening the mold in advance will cause great losses.

Su Yuanshan nodded: "Then I will change the design for you and add an LCD screen."

With that said, Su Yuanshan saved the drawing first, then opened a new circuit position on the board and added an LCD screen driver chip named YXPX01.

Now that you've already done your best, let's kill another chicken by the way.
