Chapter 11 11: Accelerator card? [Please recommend monthly tickets]

Zhang Sanlin's hand holding the report kept shaking. He looked at Xu Donghang in disbelief and asked, "Is this report true?"

"I'm not sure about this." Xu Donghang said helplessly. After all, the other party gave him a copy of the test report.

Who knows if this report is fake or not.

"Hurry up and find that young man to confirm the authenticity of this matter." Zhang Sanlin said excitedly, holding Xu Donghang's hand.

He has been researching abf alternatives for more than ten years without any results.

Now that someone has come up with the results, how can he not be excited?

Although this thing was not researched by them.

But this thing can make Huaxia Semiconductor further advance its position in the entire industry.

As a purely technical researcher, no matter who develops this thing.

In his opinion, this thing is related to the rise and fall of the entire Chinese semiconductor industry.

"Lao Zhang, don't worry. The other party left us a sample for testing. If there were no samples, I wouldn't come directly to you." Xu Donghang reassured the other party.

After speaking, he took out a piece of light yellow transparent film from the document bag.

Zhang Sanlin snatched the film from Xu Donghang's hand and regarded it as a treasure.

There is no way to tell any clues just by looking at this thing. The only way is to conduct experimental tests on it.

"I'll conduct the test right away. I'll find you when the test results come out." After speaking, Zhang Sanlin turned and walked toward the laboratory.

Han's Manor.

Han Chen returned directly to his manor after leaving Shennan Circuit.

Han Chen went to the kitchen first and took out a bottle of frozen orange juice and poured a glass of it.

After returning to the study, Han Chen put his notebook on the desk.

After turning on the computer, Han Chen found the eda installation package and instructions on the computer.

The installation package of Beidou Star eda software is divided into two parts.

The first part is the client, and the second part is the server.

The capacity of the client is only 30M, and it mainly provides customers with a cloud control interface.

As for the real functions of eda software, they are all implemented by cloud servers.

Because of the cloud service design, it is impossible to crack it unless the other party moves the server back.

However, even if the other party moves the server back, it will be useless. Even if it is moved back, they will not be able to crack the server software.

If you want to log in to the server, you need to go through multiple layers of verification. If you want to log in to the server, you must first pass face recognition authentication.

After passing face recognition authentication, you must pass fingerprint authentication, and after passing fingerprint authentication, you must enter a password.

Otherwise, don't even think about logging into the server's control interface.

As for whether it is possible to log into the system through cracking?
This technology comes from the future and cannot be cracked even with a quantum computer.

If the software is forcibly cracked, viruses will be released and destroy the computer hardware.

Moreover, this virus will also spread within the local area network. After the virus spreads, it will destroy all computers in the local area network.

The working efficiency of Beidou Star EDA is one hundred times faster than that of ordinary EDA software.

In fact, the process of designing a chip is very simple, and the entire process can be realized through code.

The most troublesome part of chip design is the simulation inspection of the front and back ends.

This process takes up 70.00% of the time of chip design.

With the continuous development of process technology and application fields, the complexity of chips continues to increase. Correspondingly, the requirements for simulation verification work are also constantly increasing.

Not only are the function points that require simulation verification becoming more and more complex, but the verification cycle requirements are becoming more and more stringent.Simulation verification is a key step in the chip development and verification process. By simulating the actual scenarios and environments of chip applications, adding test incentives and detecting chip output and status, the correctness of the chip function can be judged at the first time. .

Due to the complexity of the chip design process, simulation verification is the most important verification method during a large amount of time from the completion of the chip logic design to the use of actual chips for testing, and its efficiency has a huge impact on the chip development cycle.

Simulation verification is carried out based on the complex EDA tool using the hardware resources of the computer/server.

Obviously, the factors that determine the simulation verification speed include hardware resources and chip complexity. In addition, in the construction of the simulation verification environment, the mechanism for recording verification status and results will also play a great role in the simulation speed. Influence.

So how does Beidou Star eda solve this problem?
In order to solve this problem, Beidou Star EDA developed the corresponding AI accelerator card.

Moreover, the performance of this accelerator card can be used in a stacked manner. The more accelerator cards are equipped, the faster the test will be.

Of course the truth is not absolute.

Because if you have an accelerator card, you must have a corresponding platform to support it.

After all, the bandwidth of the chip is there. It doesn't mean that you can add it if you want, or that the accelerator card can add it.

The chip does not have enough bandwidth for you to use, and there is no way to fully utilize the performance of the AI ​​accelerator card.

Just like why computers in later generations must be equipped with solid-state drives.

Installing a mechanical hard drive cannot fully exploit the performance of the CPU and graphics card.

Your CPU and graphics card are already fast enough, but the hard disk reading speed cannot provide enough data to them.

This also results in their excessive performance being unable to be fully utilized.

To build this EDA software, you need at least 3000 million in cash.

The production of AI accelerator cards costs 500 million yuan, and the purchase of servers costs at least 1000 million yuan. The remaining 500 million yuan is used for the construction of computer rooms.

This includes broadband access and network switching equipment, etc.

For the impoverished Han Chen, this matter was still far away.

Unless Han Chen can mortgage his manor.

ummm
For now, this is the only way.

In a blink of an eye, it was 08:30 in the evening.

Shennan Circuit Laboratory.

After Zhang Sanlin received the film sample, he led the researchers to conduct experiments.

In order to confirm the authenticity of the film as soon as possible, they did not eat all day.

At this time, Zhang Sanlin had already tested the properties of the film to a great extent.

The test data is exactly the same as the test report sent by Han Chen.

Of course, meeting data standards is just the beginning.

They also need to test whether the film is up to standard in practical applications.

What if various problems occur after the film is printed on the PCB board for a long time.

Zhang Sanlin cut the film into three pieces and put them on the printing machine to print on the circuit board.

Jiang Dongfu looked at the two-foot-wide film and couldn't help but complain that Han Chen was really stingy.

Can't you give more when giving samples?

The palm-sized film made them cautious when testing it.

Han Chen really hasn't thought about this issue because he is not in this industry.

How do I know that application testing is also required.
