Tick.

Tick.

Tick......

Su Yuanshan's gaze left the long-eared iron-shelled alarm clock.

Stallone hung at the head of the bed, and Zhou Huimin was attached to the end of the bed. The desk top is covered with glass, and under it are pressed photographs of him from childhood to adulthood. Against the wall of the desk is a Yan Wu's dual-card cassette recorder with a row of English tapes on it.

A little farther away is a Laser-310 learning machine covered in red silk cloth, and the shelves are stocked with his textbooks from childhood to adulthood and a few electronic books.

This is Su Yuanshan's bedroom when he was in middle school.

February 25, 1991, the eleventh day of the first lunar month.

At this moment, Su Yuanshan has just entered his first year of high school.

If you follow the trajectory, he will finish high school in No. 7 Middle School, and then because his father is an associate professor of electronic science and technology at the University of Electronic Science and Technology, he has developed a strong interest in electronic circuits and programming since he was a child.

Then he met his wife Ye Rudai on campus one autumn.

After graduating under his father, he applied to study at Columbia University for a master's degree in computer engineering. After graduation, he joined intel, stayed for three years to witness the birth of P3 to P4, and then returned to China with his wife, and then was invited by his brother to join Guoxin as a logic design engineer of Guoxin, and his wife returned to teach at the University of Electrical Science and Technology.

After that, he worked in Guoxin for eight years, until he was exhausted, he was invited to work as a simulation tool consultant in an EDA company, until his brother invited him to join Haixin.

He has been responsible for logical design, structural design, and even microcode compilation, which makes Su Yuanshan the chief architect of Haixin.

However, it turns out that without the support of the high-end semiconductor industry, even if you can design a state-of-the-art SOC, it will only be a moon in the mirror.

......

Su Yuanshan closed his eyes forcefully and buried the past of his previous life in his heart.

Since being born again, the sentimentality of middle-aged people is not needed.

In 1991, for the domestic semiconductor industry, it was not the worst, but it was not good.

This year, while Intel was making the final repairs to 80486, he began to hold back his big moves.

And because Intel canceled the X86 authorization for other "second suppliers" in the 386 era, AMD and cyrix are using the clean room law to make Intel scold her mother in reverse copycats.

Of course, even if other manufacturers conduct white-box test replicas in the clean room - similar to dissecting a CPU, and then blindly guessing the functions that the microcode finally implements and is compatible with the original product - as long as you do the x86 architecture, you must not be able to avoid intel's various patents under this architecture.

One of the most notorious is The Crawford '338 Patent, a patent on memory management and caching that no one is said to be able to circumvent under x86.

Thanks to this, Intel wielded a patent stick and beat a group of copycats to the ground - except for Cyrix, a white prostitute. It relied on the authorization of its old Texas Instruments, and it took advantage of Intel's loopholes.

By the way, the CPUs of the copycat parties are all called XX386, XX486.

Two years later, Andy Grove, the CEO of Intel, jumped to his feet in anger and said that if the new CPU was called 586 again, it would not be necessary to step on my corpse, and Pentium was born.

- Lights, wait for lights, wait for lights.

In contrast, at this time, the domestic waste is waiting to be rebuilt - in the 80s, dozens of semiconductor production lines were introduced in China, and only a few were successfully put into production, coupled with some high-end products were imported into China, which made people born the illusion that "it is better to buy than to make".

You know, when the C8008 that imitated intel made the DJS-050, it was only five years behind.

The 908 project, which is still in the demonstration stage, will be officially approved next year, but it will be stagnant for various reasons.

Su Yuanshan remembers very well that Cadence, one of the three giants of EDA, will enter China next year and begin to crush the domestic EDA software Panda ICCAD.

A memory is like a fallen leaf full of yellow sand, which gradually becomes clear as his thoughts spread, and it also allows Su Yuanshan to sort out the context.

His eyes grew brighter.

Crush Panda CAD?

If you have 30 years of experience in using EDA software, know all the difficulties and pain points in EDA use, and all kinds of excellent algorithms in later generations, if you pull someone to make an EDA, what should it be?

Dimensionality reduction strike?

......

His mother's call interrupted Su Yuanshan's thoughts.

"Hill. ”

"Oh, Mom. Su Yuanshan wiped his face and replied with a smile.

"Hurry up and go downstairs, your brother-in-law is almost here, saying that he brought you a gift. ”

"Uncle?" This title, which had disappeared from his mind for a long time, suddenly awakened the unhappiness in Su Yuanshan's memory, and he couldn't help but say in a deep voice: "What is he doing here?"

Su Yuanshan's brother-in-law is called Zhang Ke, and he was a great talent in the family in the 80s and 90s - he teamed up with a group of people to be the master, from the south to the north, and then to the far north, and earned a net worth of millions in a few years. For this reason, Zhang Xiuyun muttered to her husband Su Xinghe, complaining that her husband was not as much as a speculative molecule as a professor.

In all fairness, my uncle is not the kind of old hat who cocks his tail when he makes money, in front of his brother-in-law who is a high intellectual, he has always respected him, and once gave a Wave 486 to Su Yuanshan's father.

But everything changed after Zhang Ke got acquainted with the cowman who made 100 million yuan by reselling second-hand aircraft.

Zhang Ke, who was still in awe of knowledge, became empty-eyed, and entered the futures market under the guidance of the bull, but lost all his pants.

Later, the brother-in-law found Su Yuanshan's mother, Zhang Xiuyun, the "brother demon" in the later world, believed his brother's nonsense that "the principal will be repaid in a month at most", and gave all the family savings to his younger brother, not to mention, and embezzled 100,000 public funds.

The results can be imagined......

Associate Professor Su Xinghe was so anxious that he almost lost his head overnight, begging talents everywhere to borrow money to fill the hole.

Although this matter was not discovered in the end, there was no peace at home since then - this is also one of the reasons why Su Yuanshan applied to study abroad in the first place.

Since then, the brother-in-law has been in a slump and has become a scoundrel who is deceived and deceived everywhere and is full of lies.

Su Yuanshan's tone surprised Zhang Xiuyun, Zhang Ke has always been very good to Su Yuanshan, and his son has always liked his brother-in-law, did this kid take the wrong medicine today?

Just when Zhang Xiuyun was about to scold, he heard Su Yuanshan's tone become pleasantly surprised.

"Uncle, I'll go down and pick him up!"

Su Yuanshan put on his coat and quickly opened the door.

Before going out, he glanced at his mother.

My mother, who is just over 40 this year, is lazily leaning on the sofa and watching TV.

"Mom, you're so young. ”

"Huh?"

Ignoring his mother's doubts, Su Yuanshan ran down the stairs with a smile.

- At this time, the uncle has not become the one who everyone hates, and he is still the uncle who is very good to himself.

When I came downstairs, my brother-in-law, who was in his early thirties, was as energetic as he remembered, with two large cardboard boxes at his feet.
