The rise of nanometers

Huizhou.

Huinan High-tech Industrial Park.

Here are Huawei's Huizhou Semiconductor Base, which was just established this year, Huawei's R\u0026D center in Bantian, Pengcheng, and Dongguan's Songshan Lake production base, forming Huawei's industrial cluster in the south.

In this industrial park, there are also three OEM companies, BYD, Great Wall, and Bourne Optics.

And ZTE, which entered Huizhou at the same time as Huawei, ZTE’s semiconductor base is right next door to Huawei’s semiconductor base.

In October, the sun is still shining brightly in Lingnan.

Huang Xiuyuan came to Huizhou from Shanmei with a group of CPU R\u0026D personnel.

In Huawei's semiconductor base, Xu Jun, who has been stationed here recently, personally greeted Huang Xiuyuan at the door.

As soon as his minibus arrived, Xu Jun greeted him: "Mr. Huang, you are welcome to come and give us guidance. Please forgive me for the poor hospitality."

"Mr. Xu, you're welcome!"

In order to keep it secret, Xu Jun did not tell others the truth. He only said that someone came to inspect, and he took a few close friends to greet him at the door.

A group of people entered the base.

The internal layout of Huawei's semiconductor base is similar to that of Long Totem. This base currently has four 40/60 nanometer chip production lines.

In addition to Huawei's R\u0026D personnel, the joint GPU design center also includes people from companies such as Dragon Totem, Ziguang, ZTE, and Datang.

Xu Jun asked in a low voice: "Mr. Huang, has your CPU design been completed?"

"The first draft was completed, but after tape-out, I found that there were many problems. I was worried about the GPU, so I came to take a look."

Hearing his answer, Xu Jun's heart suddenly jumped up: "Is the CPU tape-out not ideal? How different is it from the expectation?"

Huang Xiuyuan did not hide anything: "In the first tape-out, about one-fifth of the transistors failed to varying degrees."

"So high!" Xu Jun was even more worried, and his brows were almost wrinkled.

But then Huang Xiuyuan's words changed: "I re-adjusted and optimized it, and the number of failed transistors now is estimated to be only about 1 to 2%."

Well... shouldn't it be better to finish all the words at once? It made him feel agitated, and Xu Jun complained secretly in his heart.

Huang Xiuyuan continued: "The main purpose of coming here this time is to update the database for your design software, and then take a look at the specific design situation."

"Then I'll bother Mr. Huang."

"You're welcome." Huang Xiuyuan waved his hand and shared design data and optimization plans with a group of semiconductor companies. This was also one of the purposes of the founding of the Semiconductor Alliance.

After all, China's semiconductor industry and talents are not as good as those of developed countries. If we continue to work behind closed doors and maintain sectarian views, there will be only a dead end.

Under this model, the Suiren system, as the founder and founder of the system, actually made a lot of sacrifices and contributions.

But for China's semiconductors, the Suiren Department has no other choice.

Just like Fairchild Company to Silicon Valley, that one dandelion sows countless seeds in Silicon Valley.

The dragon totem, the dandelion, will also spread the seeds of semiconductors to all parts of China.

Arriving at the design center in the base, Huang Xiuyuan ordered Long Totem's engineers to update the database for the design software here, and they were busy all morning.

At three o'clock in the afternoon, Xu Jun and Huang Xiuyuan reviewed the design of the joint GPU.

After re-updating the database, many problems were quickly discovered in the supercomputer simulation calculation of the design conditions.

Seeing this situation, Xu Jun was frightened and broke into a sweat.

Huang Xiuyuan personally guided the design. At first, many researchers were not convinced, but soon they became uneasy.

Huang Xiuyuan, who has a photographic memory, discovered 27 serious design errors in a few hours based on the overall combination of transistors and his future memory.

In simulation calculations, his accuracy was also verified one by one.

Xu Jun on the side, although not a specific technician, is somewhat familiar with GPU design. For more than half a year, they have been designing while using supercomputer simulation calculations and manual troubleshooting. On average, it may take three or four days to find a problem.

This is why a large number of problems will be discovered after tape-out, because before actual manufacturing, the design simulation calculations have distortion differences and cannot 100% simulate actual manufacturing.

People on Long Totem's side are still used to Huang Xiuyuan's super memory and human brain simulation calculations.

Designers from other companies just have to worship him.

In the lounge.

Xu Jun poured him a cup of tea himself: "Mr. Huang, take a rest."

"Thank you." Huang Xiuyuan took the tea cup and drank the tea calmly.

Xu Jun looked at the design optimization status of the past few days. After reading the report, he finally knew why the Fuxi CPU problem could be solved in a short time.

Faced with a pervert like Huang Xiuyuan, one person can basically support an excellent design team, and because it is one person, the overall matching and correlation of the chips can be handled more perfectly.

In response, Xu Jun could only shake his head helplessly: "If there are more geniuses like Mr. Huang, this project can be doubled in speed."

Huang Xiuyuan smiled and replied: "Individual wisdom and strength are limited after all. We still need to promote group cooperation."

In this regard, although Xu Jun recognized the power of groups, it was the first time that he felt that the limits of individuals could reach such terrifying levels.

No wonder every time the developers of Dragon Totem mentioned the founders of the Suiren series, they mostly admired Lu Xuedong's performance, while they had an almost blind worship of Huang Xiuyuan.

Now Xu Jun finally understood that even if he was determined, he could not help but develop a kind of trust, believing that the other party could create miracles.

Stayed here for more than a week.

Huang Xiuyuan pointed out various problems in the joint GPU design, and discussed some adjustments to the joint GPU with several project leaders.

On the multimedia projection screen, some of the problems he discovered in the past few days were shown: "This is the first time for you to design a GPU, so it is understandable that you lack experience. Now you have a big problem, and that is the matching problem of the GPU."

Dr. Yang Chao, the person in charge of Huawei, saw a small number of incompatibilities in simulation experiments between GPUs, CPUs, and other chips in simulation calculations.

This problem is very serious. You must know that chips rarely work alone. Many of them need to be matched with other electronic components. If there is incompatibility, then the chip design will be of little use no matter how perfect it is.

Huang Xiuyuan is also very troubled by this problem: "The current problem is that because the CPU has not been released before, you have been working behind closed doors. You must communicate with the CPU project team as soon as possible to ensure the compatibility of each chip."

"I understand." Yang Chao's expression was solemn.

Several other people in charge are also having headaches. Fortunately, this problem has been discovered now. If it had been a little later, when the GPU design was finalized, and it was discovered that it was incompatible with the CPU, it would be really embarrassing and troublesome.

This is also the difficulty of the new semiconductor system. Everything is difficult at the beginning. The development of a complete set of chips requires not only design and manufacturing, but also the cooperation between spare parts. This kind of running-in takes a lot of time.

Faced with this situation, Huang Xiuyuan has already planned to postpone the launch of mobile phones and computers from March next year to June next year.

This means that plans cannot keep up with changes.

Thank you for your support. This is the first update today. I was so tired yesterday that I fell asleep (-_-) zzz
