Chapter 139: Efficiency Maximized
EDA software is generally used in chip design, which can complete the design of hundreds of millions or billions of transistors through code.
And this plotter saves even the need to write code.
For the front-end design of the chip, it can be simply understood as the circuit logic design of a single transistor. It is like a single house in a city. The structure of the house determines its function.
This generally does not save effort and tests the design ability of engineers. Good engineers can design the most reasonable structure of the house, while inferior ones have many drawbacks or can only design a single type.
Since CMOS has fewer types of transistors, the workload of front-end design is less.
The one that Kang Chi got last time at the Jiangsu Microelectronics College can be used directly after a little improvement.
But the physical design drawings at the back end are much more complicated.
This requires writing a lot of code to continuously debug the layout of billions of transistors and design a reasonably laid out megacity.
But this plotter can automatically complete the structural arrangement and planning layout according to the scope drawn by Kang Chi and the definition of the system architecture!
It’s like Kang Chi gave it a few house design drawings, then marked an area and told it that I want to shoot an industrial zone here, and it automatically generated an industrial zone with a reasonable layout.
After that, it also actively conducts simulation verification, and kindly reminds you where to shoot and how big the residential and commercial areas should be.
With it, designing chips is like playing a game.
Even if someone who doesn’t understand chip design at all, after a week of training and learning, it is estimated that he can get started with back-end design.
At this time, Kang Chi just wants to say, Fuck,
Awesome! If this thing is taken out, it will directly collapse EDA and major chip design companies!
At least 90% of chip backend designers will be unemployed, and the remaining wages will also be greatly reduced! It turns out that holographic projection technology is just a bonus.
The real power of this design machine is the design program inside! With the help of this intelligent design system, Kang Chi completed the design of a 20-megapixel CMOS chip in just one day.
The efficiency is simply terrifying.
After completing the chip design, Kang Chi called Dong Jianyuan directly.
Dong Jianyuan happened to be eating at home at this time. When he saw that it was Kang Chi’s call, he didn’t have any temper at all. He immediately put down his chopsticks and went to the study to answer the phone.
Kang Chi rarely contacted him, and every time he contacted him, there must be something important.
“Mr. Kang? It’s me.”
”Well, I need your help.” Kang Chi skipped the small talk and got straight to the point, “Help me make a chip mask. The sooner the better. Just quote the normal price.”
”Just a mask? No need to tape out?”
”No, I can tape it out myself.”
Dong Jianyuan’s eyes widened immediately, and he asked anxiously, “Have you made the EUV lithography machine?”
”What about you making a tractor?”
”…”
Dong Jianyuan was silent for a moment before nodding. “Okay… Then send me the GDSII file and I’ll arrange it as soon as possible.”
”Well, thank you for your help.”
”It’s okay… Well, can you do me a favor?”
”What favor?”
”If you make an EUV lithography machine, sell a few to our Shencheng Silicon Industry first.”
”No problem, but I have to meet my own needs first before selling it to others, and then I’ll give priority to you.”
”That’s enough!”
With Kang Chi’s promise, Dong Jianyuan was relieved.
Since Kang Chi helped Chang Chunguang get the EUV light source last time, it’s no secret that he is developing EUV lithography machines, but some people are optimistic and some are not.
Dong Jianyuan is naturally optimistic.
Although Kang Chi’s answer made him a little disappointed,
But Kang Chi was right. The photolithography machine is not a tractor. He has only started for two or three months. It is normal if he has not figured it out. It would be abnormal if he has figured it out.
As for his own tape-out, it is estimated that Kang Chi got a photolithography machine from somewhere and used it for reverse research…
After ending the call with Dong Jianyuan, Kang Chi used the WiFi transmission function of the plotter,The GDSII file of the chip was imported into the computer, and finally encrypted and sent to Dong Jianyuan.
After finishing this, Kang Chi began to study another function of it: Scanning and modeling of physical objects!
This function is not rare. Many mobile phone programs can use the camera and gyroscope to shoot an object to generate a three-dimensional model, and even directly have textures.
However, this function is currently mainly used for entertainment.
Not to mention such a sophisticated thing as industrial design, even game modeling is not very useful…
Because the model generated by scanning in this way has too many points, lines and surfaces, and the volume is very large,
If it is used directly to make games, the size of the game can be imagined…
So it has to be optimized,
But optimization is more troublesome than doing it directly.
Just like writing a novel with voice input method, it may be fast and fun when speaking, but when you modify it later, you will find that it is not as fast as typing directly on the keyboard.
Kang Chi did not try this function right away because he did not have high expectations for it.
But after using it for two days, Kang Chi no longer dared to underestimate the function of this plotter.
He took a part from the camera at random, and then placed it in the projection area and rotated it several times according to the prompt. Finally, he changed the handshake position and rotated the sample again.
Soon, the plotter made a beeping sound, and a three-dimensional part popped out.
Kang Chi only took a look and basically determined that this function was really useful! Because it is so simple!
There are no extra points, lines, and surfaces, and the degree of simplicity can be adjusted at the same time.
If it is adjusted to the highest, even the frosted undulations on the surface of the part have line structures.
If it is adjusted to the lower level, it is the most suitable basic model.
You only need to check and adjust its various parameters, and the drawing of a part is basically done.
At this time, Kang Chi wanted to add one more sentence, Fuck,
Awesome! With this function, it will be much more convenient to convert upgraded items into blueprints in the future.
Of course, for something like a photolithography machine, which is obtained by analyzing the graphics card, you still have to draw the blueprint yourself without making the physical object.
In addition, if it is something particularly complex, precise and small, it is not suitable. Maybe the time to disassemble the parts is enough to draw the blueprint.
Although there are certain limitations, with the help of the plotter, Kang Chi’s work efficiency is still directly maximized, and the speed of blueprint output is one day to one week.
While steadily advancing the photolithography machine project, Kang Chi only took five days to complete all the camera blueprints, and then sent them to He Yongbin in the camera R&D department.
