Chapter 22: Extreme Shock (Ask for recommendations, old iron, please!)

The afterglow of the setting sun was sprinkled, a little dazzling, and on the chair in front of him, a slender figure appeared.

Wang Anran sat up, and the recliner creaked, alarming Shan Lei.

"You're awake! ”

Shan Lei turned around, and the fluff on her neck was clearly visible, which made people have a desire to explore.

Wang Anran took a deep breath......

"You care so much about me, do you have anything to eat?"

Shan Lei stood up and said, "What do you want to eat?" I'll buy it for you. ”

"Noodles, beef knife sliced noodles, add a spoonful of chili oil, preferably the one in the Shanxi noodle restaurant in Dongmentangzi Hutong. ”

"You have a really strong taste, the Shanxi noodle restaurant has a few jars of old vinegar at the door, and you can smell the sour smell of the boss every few streets. ”

"That's old vinegar, good stuff, it makes my mouth water when I think about it. ”

Shan Lei picked up her shoulder bag and went out.

Wang Anran watched Shan Lei's back disappear, turned around and opened the terminal of the duty room, and called up the results of last night's hard work.

The design of this video chip has completed the front-end design, that is, the logic design, and the physical design at the specific level.

In other words, these logic circuits need to be represented at the physical level, down to the basic unit of transistors.

The whole work is not completed until the simulation test of the entire physical chip is completed.

For example, when designing a building, the front-end design is equivalent to the architect, whose task is to design the shape of the building, the interior layout, the division of functional rooms, and so on.

The back-end design is the equivalent of a structural engineer, whose task is to equip the building with reinforced concrete and turn it into a construction ready drawing.

In the back-end design stage, the power of EDA chip design software can play a role, just like the automatic reinforcement of structures in architectural design software CAD, EDA software can automatically design the physical level according to the front-end logic chip drawings.

All Wang Anran needs to do is click the mouse, then drink tea, read the novel, and wait patiently.

I didn't expect to relax for less than two minutes before I heard someone talking.

"Wang Anran, can you still be a little responsible, a butt of shit, don't wipe it yourself, and run here to relax. ”

"Oh, Mr. Lu, why is your old man here, sit down. ”

Wang Anran hurriedly gave up his seat, took the teapot in Lu Wei's hand, and refilled the water.

"I said Anran, what the hell is going on with you, now there are hundreds of people asking for money at the gate of the Automation College, and the entire college is surrounded by water, so I will ask you, whether this student still wants to go to class, whether the research project still needs to be done, and who will bear this responsibility. ”

Anyway, it's not me, Wang Anran shrugged his shoulders and said, "Teacher, I can't help it, Wan Yan gave me shares, but didn't give me money, and when I went to the bank to mortgage the shares, the valuation given by others was only 500,000, which was only enough for a fraction."

Besides, the application form you gave me has been more than a month old, and it is still under review. ”

"Then you can't help but show up, at least you should lead them somewhere else. ”

Wang Anran smiled and said: "Teacher, I'm not busy! Besides, you have always taught me that the sky is falling, and there is a tall man on top of it, this is not a good thing for us to say, the college will endorse me." ”

Lu Wei touched his head and said a little puzzled: "Did I say this?"

Then he came back to his senses, stood up and said: "What are you busy with, Wang Anran, you spent 7.5 million yuan to build a set of software, you can really do it, today I just came to see what you have come up with, if you mess around, I don't care about this matter, I will expel you from the division today." ”

Wang Anran stepped forward to help Lu Wei sit down, and said with a smile: "Look, you are old and anxious, you usually teach me to raise Haoran righteousness, but when it comes to yourself, it won't work, if the upper beam is not right, don't complain about me when the lower beam is crooked." It's not easy to look at the software, you just have to go back. ”

As soon as Lu Wei turned around, the progress bar on the screen behind him had reached 97%, and after more than ten seconds, as the progress bar reached 100%, the preliminary design of the entire physical chip was completed, and the software automatically generated the physical layout in GDS file format.

"This ...... This ......"

Lu Wei was speechless for a while, this is a chip, what kind of demon did he receive.

Wang Anran unfolded the physical layout of GDS, and the physical composition of the entire chip was clearly displayed on the screen.

"Teacher, this is just a preliminary design, there is also a need for simulation simulation, electrical simulation, clock simulation, you see this diagram, this is the operation unit, this is the logic unit, this is the data register, this is the ......"

Lu Wei took a sip of water, suppressed the shock in his heart, and asked: "What kind of chip is this, is it designed with this software? Can you show me a demonstration? Just design an empty chip and try it......?"

Shan Lei felt a storm in her heart, put the lunch box on the table calmly, and said, "Professor Lu, Wang Anran debugged all night yesterday, and he hasn't eaten for a day, or will you talk slowly after he has eaten?"

Haven't eaten in a day?

Debugging overnight?

Thinking about the school's investigation, Wang Anran downloaded more than 70 trillion pieces of information on foreign websites in July alone, so how much data did he download throughout his college career.

Sure enough, success didn't happen by accident.

"Anran, eat, eat, eat, let's talk after eating. ”

……

Lu Wei opened the software, waited for about two minutes, the program was loaded, and two options appeared on the interface, "front-end design" and "back-end design".

Open the front-end design, and several interfaces such as "HDL Encoding", "Simulation Verification", "Logic Comprehensive Design", "SAT Static Timing Analysis", "Formal Verification" and so on appear

One item, Lu Wei is no longer surprised to describe, although he has not verified it, but he also knows that this software is not a showy thing, it is genuine.

And the closed disciples who were caught by themselves are afraid that their research on chips has far surpassed their own.

It's really terrifying, and I am a teacher.

Lu Wei tried to open the back-end design again, and the same as the front-end design, the simple interface is divided into several functions, "layout planning", "GTS clock test", "logic gate circuit layout", "parasitic parameter extraction", ......

These functions are the basic process of chip design, Lu Wei knows very well, but there is one function that he has not seen.

"Anran, what is this function for, it says: automatically generate ....... ”

Wang Anran just swallowed a mouthful of noodles and said, "Literally......"

"You mean ......"

Lu Wei didn't know what to say anymore.
