Rebirth: I carry a desktop computer inside me

According to the project experiment plan, Xu Dawei has led Jiang Cheng's team to complete the second part of the experimental content, and the next step is circuit design.

In this regard, Jiang Cheng recommends using his own SF circuit design and simulation software.

"Well, Xiaojiang, you show us all your software tomorrow and see how it works," Xu Wei suggested.

For Tang Jianshi and others, the circuit design and simulation software they generally use is mainly EWB, and they are not familiar with Jiang Cheng's software.

Not very convinced.

"Okay, I'll clean it up tomorrow." Jiang Cheng nodded.

"Everyone rest, come to the lab tomorrow afternoon." Xu Wei was also tired and needed to rest.

Everyone dispersed happily.

The initial success of the project finally brought a successful end to the high-intensity preparation experiment in the past half a month.

At least, the hard work was worth it.

But Jiang Cheng was left behind by Xu Dawei.

"Xiaojiang, you can sort out this experiment and declare a few patents." Xu Wei reminded.

Jiang Cheng blinked, I was also tired.

Xu Wei said, "It will be okay in the next few days, we must declare it as soon as possible." "

Preparation methods like these cannot be completely confidential, but some methods are more clever, but there will be a day when others will find out."

Then if you do not declare a patent and are declared by others, you will easily become an infringing party.

Therefore, patent filing is mandatory.

Moreover, in this series of experiments, the steps can be decomposed, whether effective or invalid, and a number of patents can be fully declared.

In the past half a month's experiment, for Jiang Cheng, in fact, only two of the schemes proposed by his supercomputing simulation experiment in vivo were tested.

Jiang Cheng has also been continuing to simulate to find a better and better preparation method.

Hey! To be honest, Jiang Cheng is now a simulation addict.

He directly simulated a lot of experimental materials into the in vivo laboratory.

To this end, he also specially established a library of experimental materials, and there are already hundreds of types of materials.

The entire simulation lab is already huge.

There are 6 special experimental workshops planned and designed, including a 28nm wafer production line with a 197nm (hard modified 134nm) lithography machine; chip design and verification laboratory; semiconductor preparation and testing laboratories; Mobile phone assembly and testing laboratory; Optics and Objective Lens Laboratory; New lithography machine complete laboratory.

There are instrument libraries, material libraries, finished product warehouses and so on.

It has become a huge scientific laboratory in Jiang Cheng!

And it's an unlimited number of material copies, an unlimited number of experiments, plus the kind that has no experimental cost.

Jiang Cheng was going to name him: Super Technology Lab.

However, before that, Jiang Cheng just wanted to come with a good night's rest.

He was so tired.

----- ( ^_^ ) -----

the next day, Jiang Chengyuan copied the Fenghuo SF circuit design and simulation software to the Institute of Microelectronics.

"Oh, this is the software you made yourself?" Tang Jianshi glanced at it and felt a little curious.

Does Hua Guo really have its own EDA design software?

Jiang Cheng nodded, and handed over a thick handout, "Yes, this is an introduction to the use of software that our team has initially compiled. Tang

Jianshi no longer had the original contempt for Jiang Cheng, and took the handout very seriously and looked at it.

Although he can't design EDA tools, as a doctor who often designs circuit projects, he still has the most basic judgment on the quality of a piece of software.

Xu Wei glanced at it and asked, "Have you produced any excellent results in this software?"

"Now my chip team is using this software to design new SOC chips." Jiang Cheng explained.

Not only that, the IC R&D department is also using it, ready to design lower process RF chips.

Xu Wei nodded slightly, "No wonder you have always wanted to push the lithography machine industry alliance, now use your own EDA tools, if you don't have your own lithography machine, the new process is estimated to be difficult to foundry, right?"

"Yes, if it is a 45nm process, it is better, if it is 28nm, or even more advanced process, with our own design tools, I think Huaxin International has no way to help foundry." Jiang Cheng sighed and said, "This is someone else's industrial chain. "

What happened to the Lithography Machine Alliance?" Xu Wei asked.

"There are eyebrows," the corners of Jiang Cheng's mouth raised slightly, "I hope that our project will end as soon as possible, so that we can deal with the lithography machine as soon as possible." Not

only that, Bing Shaoqing and the team continue to develop comprehensive tools, layout verification tools, etc., in addition, they must constantly update the component library of the design software according to the process process.

The current memristor memory is not high in the process of technology, and there is no problem with using Jiang Cheng's design tool.

Jiang Cheng is already very experienced in circuit design.

Under his leadership, everyone had a detailed discussion on the design of the new memristor, what functions to achieve, and how to design the front-end and back-end for several days.

In the end, it was decided to refer to Jiang Cheng's plan.

Because what he said was very reasonable, he also drew a general idea and idea on white paper.

It was as if he already had a circuit design in his mind.

Too strong!

Is the current direct Bosheng so powerful?

Whether it is Dr. Tang Jianshi or Dr. Li Xinyi, their vision is very accurate, and Jiang Cheng's future will definitely be broad.

Perhaps, he really hopes to be the one at the top of the computer field?

Soon, according to the division of labor, Tang Jianshi, plus a few graduate students who came to do miscellaneous work, began circuit design.

Of course, they are responsible for the simpler part.

According to Xu's requirements, it is necessary to store at least 1MB of data through the change of current, and at the same time be able to have basic computing functions.

That is to say, there is no need to use the processor, by entering the given value, in the memristor can directly calculate the result and save it inside.

Of course, the principle of in-memory computing can use multi-level resistance states to realize multiplication-addition operations in the analog domain.

Jiang Cheng chose to connect multiple memristors in series to achieve a complete logical operation method.

A whole month has passed.

After several verifications of Maple Fire SF circuit design and simulation software, Xu Wei took the memristor material and design to the tape-out without problems.

Dozens of memristor chips were perfectly made.

On a specially made motherboard, several people very carefully arranged eight memristors symmetrically, and the pins were soldered to the board.

Then the test is started with electricity.

The results of the test, via binary numbers, are output to the screen.

Xu Dawei personally tested and entered the 1+1 instruction.

The results came out instantly, 10.

A number of other logical operations were then tested, and the results were reliably flashed.

Not only that, but all the calculation results can be stored.

Some data calls, if the data has been stored, can be directly calculated on this basis.

Much faster!

"Great! We finally succeeded!

"It's incredible, the memristor that integrates storage and calculation has really been researched by us!"

"It's a day to remember!"

That's a great step forward!

The crowd cheered.

Although this is only a rudimentary memristor with a process of only 1 micron.

But on this basis, they can develop a more powerful memristor!

Due to the ingenious technical process and good cost control, Jiang Cheng believes that it is not far off in the field of chip storage!
