On the second day of the May Day holiday, it was raining heavily outside the window. It was really not the right weather to go out for fun.

So Qin Ke and Ning Qingyun did not go out today, but stayed at Xingguang Mingyuan's new home to conduct research together.

The thesis on tomato breeding has been completed, the patent application process is accelerating, and the academic report materials for the Scientific Breakthrough Award have been finalized. Now the only scientific research topics at hand for the two of them are the hail conjecture and EDA design.

——There is also a desert sweet potato project that is estimated to have to wait another month or two to start, because it is very time-consuming to collect different varieties of sweet potato seeds from all over the world. And the hybrid breeding of desert sweet potatoes requires repeated crosses of more than ten varieties.

It was cultivated, but the specific sweet potato seed name was not marked in the A-level knowledge. It could only be determined by Qin Ke's trial planting of varieties from all over the world in the virtual scientific research and experimental center.

Qin Ke stretched and stood up to make a cup of lemon tea for Ning Qingyun.

Passing by the window, Qin Ke glanced out the window and saw that everything he could see was covered with rain, and there were very few pedestrians outside. It rained particularly heavily in the north this year, and he didn’t know if Professor Duan’s J-92 breakwater project had started.

Promoted?

Qin Ke was particularly impressed by this very large project that he had participated in for the first time. Well, I would like to send a message to Professor Duan when I have time to ask.

When Qin Ke made lemon tea and returned to the study, Ning Qingyun was still typing on the keyboard of her fruit notebook, perfecting a small algorithm for EDA.

In the past few days, Qin Ke has basically taught Ning Qingyun his algorithmic knowledge related to informatics and chip design through "thinking resonance". Ning Qingyun has officially practiced on the computer today.

After Qin Ke explained the main idea of ​​an algorithm to her, Ning Qingyun enthusiastically expressed that she would improve it independently and compile the code herself without the help of Qin Ke and Weiguang to verify her mastery of algorithm knowledge.

This degree is regarded as the "graduation examination".

Naturally, Qin Ke would not object. Anyway, it was only a small algorithm with a few hundred lines of code, and with the main idea, Ning Qingyun could completely handle it. And it is indeed necessary to apply what you have learned to truly master the thinking of mathematical modeling.

Perfect the essence of the algorithm.

What's more, this kind of seriousness and concentration are also very cute and attractive advantages of Ning Qingyun.

Qin Ke sat back next to the girl, holding his chin and staring at her fair and tender face.

The girl usually listens to Qin Ke's words at home and wears her waist-length hair as smooth as a waterfall, so her originally somewhat proud and cold temperament turns into a moving and charming one.

Ning Qingyun's appearance still remains the same as on her eighteenth birthday, with her soft and delicate facial lines, bright and beautiful phoenix eyes like stars, gracefully curved slender eyebrows, fair and lovely high bridge of nose, and rosy and pink eyes.

Lips, a small chin that is slightly pointed but slightly rounded, and white and slender little fingers that are typing on the keyboard...

It can be said that everything is beautiful and beautiful everywhere. Even though he has watched it countless times, Qin Ke still feels like his heart is beating.

In Qin Ke's eyes, everything about his little cabbage is perfect, so cute, and so attractive to him.

For example, the focused look on her face as she stares at the screen, the thin eyebrows and the tight red lips that she inadvertently frowns when she is thinking seriously, all make people unable to help but feel a kind of love that hurts her to the core.

.

It is said that love is first born from the appreciation of appearance and figure, but Qin Ke remembered that when he was sitting at the same table with Ning Qingyun, he actually had no special feelings for her, because at that time Qin Ke only had learning in his eyes, and only the stars and the sea.

He didn't care whether the girl was beautiful or not. It wasn't until he had been in contact with Ning Qingyun for a long time and was attracted by her pure, shy, serious and strong temperament and character that he seemed to have opened a new door and learned to appreciate her.

The beauty of girls, and then I was pleasantly surprised to find that the girl I liked seemed to be the prettiest and most perfect girl in the world, so I felt like I had unexpectedly received a treasure and should cherish it even more.

To this day, even though he has truly possessed the girl in front of him, this feeling is still very strong.

He just admired Ning Qingyun quietly, his heart full of tranquility and warmth.

But soon he discovered that the girl's pink face, which was like top-grade white porcelain, was quietly stained with a layer of crimson. It must have been his unscrupulous gaze that made the girl shy.

Sure enough, Ning Qingyun turned around, blushed and widened her beautiful eyes and asked: "You...why are you looking at me all the time?"

Her voice had a cute nasal sound, and her tone seemed to be protesting and coquettish.

Qin Kele was amused and put on a rogue look: "I just like to see you, don't I?"

The girl shyly looked away and whispered: "You've been watching it for several years and you're still not tired of it?"

"Don't say that I only watched it for two or three years. Even if I watch it for a lifetime, I will never get tired of it. I will only like it more and more the more I watch it."

"You can coax me with sweet words...I won't be fooled." Ning Qingyun said this, her tone was clearly full of sweetness and happiness, and there were glistening water waves rippling in her eyes. Her pretty little face was compared with

The innocence of the past is now two points more charming.

Qin Ke felt that he really loved this girl so much that he couldn't help but hug her waist tightly and peck her delicate lips gently.

"Jun'er, you've been in front of the computer for so long, do you want to take a break?"

Ning Qingyun's face turned even redder, even hotter than the sunset. She lowered her head and said weakly: "Isn't it all last night... isn't it... it's broad daylight now... can we wait until tonight..."

Qin Ke almost laughed, but Ning Qingyun misunderstood.

In fact, Qin Ke is such a person who doesn't cherish his girlfriend. With Ning Qingyun's relatively delicate physique, she would be exhausted every time she "visited" the room with him. After a good sleep and practicing the Oriental Secret Code together in the morning,

, her physical strength has not been fully restored, her expression is still a little lazy, and her body is a little limp. How can Qin Ke have the nerve to take her to "visit" the room now?

This chapter is not over yet, please click on the next page to continue reading! At least let her relax for a day.

Qin Ke pretended to be embarrassed and hesitant, and after a while he "beared the pain" and said: "Okay, then I will 'visit' the room with you in the evening, but now you really need to take a rest, sitting and facing the computer screen for a long time

None of them are good.”

"Yes." The blush on Ning Qingyun's face slowly faded away. She obediently picked up the lemon tea Qin Ke made for him, drank it in small sips, and walked slowly in the study.

.

The platinum and diamond ring in the shape of a cat that was always worn on the ring finger of the girl's left hand shined exceptionally brightly against the transparent glass. The corners of Qin Ke's mouth turned up proudly and warmly.

Since putting on this ring on her birthday, Ning Qingyun has never taken it off except for taking a shower and washing her hair.

This kind of small details that obediently abide by the rules that become his "property" always make Qin Ke feel particularly happy.

After Ning Qingyun finished drinking the lemon tea and put down the cup, Qin Ke went over to hold her hand and walked together in the new house.

"EDA software is indeed critical. Last semester we took an elective course on integrated circuit design. Didn't the teacher say that? With the assistance of automated design with EDA software, the design cost of 14nm chips exceeds 1 billion yuan, and even more so for 7nm chips.

Spending more than 3 billion yuan, if there is no EDA assistance and all relying on manual labor, even if we gather engineers from all over the country and spend hundreds of billions of yuan, we may not be able to design it. At present, our country's EDA is still very weak and cannot design high-performance high-end products.

Chip, this problem is very challenging and meaningful. Even if Teacher Xu doesn't come to me, I will probably carry out this topic in the future."

Qin Ke felt the delicate softness between the girl's fingers while talking about their EDA project:

"If you want to develop a useful EDA, being able to program is only secondary. The key is to know both the chip design and the chip manufacturing process. Mr. Xu's information was all sent over last night. I took a quick look and found out that

We will sort out the parts you need to see, and you can read them when the time comes."

"Of course, the development and update of EDA software are inseparable from the chip manufacturing process. It also requires the close cooperation of major chip manufacturers, especially wafer factories, to provide appropriate data for simulation. Teacher Xu will take care of this aspect, so we don't have to worry about it.

Already."

"The EDA this time was provided by Huaban, and it is less than half complete. However, the main framework is pretty good. I plan to re-optimize it and redefine the framework and technical architecture to achieve modularity like the Lime operating system.

In this way, it can be applied whether it is facing the 14nm process technology or... in the future. It only needs to update the algorithms in the design module and engineering library."

"Originally, I really wanted to develop an ideal full-process EDA. It is estimated that it will not be possible in three to five years. The code size will not be smaller than that of the Lime operating system. But now there is 'Shimmer' that can automatically program, and I plan to do it between the two of us.

Responsible for writing the rules and framework, and then let Mr. Xu’s team fill in the details, and finally hand it over to ‘Wimmer’ to write the code, which can greatly shorten the development progress...”

Ning Qingyun didn't speak, just listened to Qin Ke's plan quietly, but a faint smile couldn't help but appear at the corner of her mouth.

Whenever we work on a project together, she always feels an indescribable sense of satisfaction. The feeling of walking side by side and working together toward a goal is so wonderful that it makes her feel happy. And she really

She really likes to see Qin Ke talking confidently, and she can't help but admire him.

This is probably the only boy in the world that she can truly admire and even look up to with admiration.

…

EDA is indeed an indispensable key software in chip design. It covers almost the entire process of chip design, including design, simulation, verification and other aspects. Generally speaking, EDA also has subdivisions, and different manufacturers have different focuses, and even some EDA is specifically responsible for only a certain aspect, such as IC design, electronic circuit design, PCB design, etc.

The chip design team often has to switch between different EDAs, conduct repeated designs, and then find the foundry to verify that it is correct before generating a complete chip layout file and delivering it to the foundry for production.

This is the preliminary design work for the birth of a chip.

The special requirements of EDA are too high and very complex, and there is no room for any mistakes, resulting in extremely high R&D investment. Another difficulty is that the three giants basically monopolize the interface IP through intellectual property rights, and once EDA leaves These interface IPs are equivalent to rebuilding a brand new front, which requires the cooperation of foundries.

Hua Petal, a semi-finished EDA, is taking this path. Fortunately, the superiors have provided strong support regardless of the cost, and domestic wafer factories have also expressed their full cooperation, so this extremely difficult road has a glimmer of hope for success.

But it is only a "tiny". Domestic chip talents are still too lacking, especially all-round chip talents.

However, for Qin Ke, with the design ideas and algorithm ideas provided by the system, complete basic knowledge of chips and informatics programming knowledge, and master-level mathematical modeling thinking, he wanted to The difficulty of navigating this road is greatly reduced.

Don't underestimate the design idea, it's equivalent to someone pointing out the direction that will definitely lead to success, and pointing out every key node along the way. All you need to do is walk this road to success step by step.

Especially the algorithm idea, as long as the details are perfected, it is enough to form the most important engineering library in EDA. The so-called engineering library mainly refers to the standard unit library, reusable circuit module library, IP library, etc.

Qin Ke re-adjusted the framework of the original petal EDA to make it conform to his own modular design ideas, and retained the original results as much as possible, including process parameter library, component graphic symbol library, component model library, etc. Then detailed rules are formulated for each module. Every time a part is completed, it is sent to Xu Qingyan and he is asked to organize his team of engineers to fill in and improve it according to the rules.

This chapter is not over yet, please click on the next page to continue reading! Ning Qingyun is mainly responsible for improving the algorithm part. With the guidance provided by Qin Ke, it is much easier for Ning Qingyun to improve the details of the algorithm, and even the really difficult ones can be solved. Discuss with Qin Ke.

Time passed in such a hurry, and a month passed in the blink of an eye, and it was the end of May.

The anxiety and irritability in Xu Qingyan's heart slowly disappeared.

Originally, the new EDA design idea sent by Qin Ke made Xu Qingyan's research team somewhat skeptical. After all, it was different from the current mainstream EDA software. However, Xu Qingyan insisted on re-formulating the plan according to this design idea, and everyone could only Comply reluctantly.

However, they were soon shocked by the detailed rules that Xu Qingyan forwarded again and again. The seemingly unconstrained design ideas, enriched by the detailed rules of these modules, formed a big tree with lush leaves, and there were hidden hidden meanings.

Soaring momentum.

When they heard that these materials were designed by a chip expert codenamed "Q" specially arranged by the superiors, everyone in the team was even more amazed.

You must know that there are no more than twenty top experts in the country who only have code names and whose identities are strictly confidential! I didn’t expect that Director Xu could apply for such strong support!

The entire team had no objections and fully cooperated, making the EDA project continue to advance.
To be continued...
