1991 Starting from the core

Su Yuanshan and the others were very lucky. Deputy Director Zhou was in the office at this time.

Like all researchers who focus on scientific research, Zhou Boguang is not good at dealing with people. Compared with Jia Jibing's arrogance, Zhou Boguang has a more serious temperament as an old-school scholar.

After reading the letter of introduction, Zhou Boguang did not make any comments or show any contempt. He took out a piece of paper from the drawer and handed it to Tian Yaoming: "Can you fill it out in ten minutes? Fill it out and I'll sign it. Jay will take you to tape-out—do you know the tape-out price?"

"I know, we've prepared it." Tian Yaoming smiled. Before the change, it would have been difficult to get into a large state-owned factory like Huajing. But because the project was launched ahead of schedule, now he is as poor as a ghost. He wishes that someone would come to tape out every day. .

But after seeing that there was only one project order, Tian Yaoming smiled bitterly and said: "Professor Zhou, one is not enough, we have three chips."

Zhou Boguang was slightly startled. He didn't expect that Dianke would actually produce three of them at once... But it is estimated that these are chips that several research groups of Dianke had developed long ago, and they were put together and put into production in the form of a private enterprise—— This is also a relatively new way of monetizing technology, and Zhou Boguang actually appreciates it. He has always believed that technology should be used and that technology that is not used will be useless no matter how powerful it is.

So he took out three more project orders and handed them to Tian Yaoming. He picked up the tea cup and asked casually: "What kind of chip are you?"

"The Chinese information encoding chip of the wireless paging station, the Chinese decoding chip of the wireless pager and the central control chip."

"Pfft..." Zhou Boguang sprayed a sip of tea into the cup.

Su Yuanshan and Qin Weimin looked at each other and smiled - this should be a normal behavior.

It has been eight years since paging stations entered the country in 1983, but paging stations and pagers are all foreign brands without exception.

Zhou Boguang quickly realized his gaffe. He stared at Tian Yaoming and said solemnly: "You mean, your Electrical Engineering Department has completed the domestic production of a complete set of Chinese pagers?"

At this time, Qin Weimin interrupted: "Professor Zhou, it's not our Department of Electrical Engineering, it's our Yuanxin."

"You Yuanxin?" Zhou Boguang picked up the letter of introduction: "The one where Associate Professor Su Xinghe has a stake?"

Qin Weimin nodded: "Yes, Professor Su is my mentor. This is Professor Su's son, Su Yuanshan."

When they were introduced just now, Chen Yujie only introduced Qin Weimin and Tian Yaoming, one with a master's degree and the other with a doctorate. He did not introduce Su Yuanshan, who looked like a college freshman at best.

Zhou Boguang took a deep breath.

As a deputy director who came from the Semiconductor Research Institute and has been in charge of technology, he certainly knows how difficult it is to design an IC chip. Especially this kind of codec IC has always been monopolized by foreign high-tech companies relying on their early start and strong technical strength. Now this private company has actually come up with it!

"Do you have independent intellectual property rights?"

Qin Weimin is very proud: "Full independent intellectual property rights."

Zhou Boguang's eyes shrank again. As someone with a technical background, he almost subconsciously thought this was nonsense! But he immediately realized that he dared to use it for tape-out, which meant that it had at least been demonstrated and designed, and it couldn't be a joke! This is not the God of Wealth department, so why are they lying to me?

Could it be the design of a foreign company that they bought at a high price? Do they have that much money? This is Chinese paging, a blank product in the market! Who would be crazy enough to design it and sell it to a domestic individual company?

Zhou Boguang's eyes moved around, and his eyes stopped on the young man who had been smiling and silent, and remained calm in the face of a group of masters, doctors, and himself.

At this time, the young man also looked at him, with a ray of respect and the composure as if seeing an acquaintance in his eyes.

…

Su Yuanshan knew that there were ten thousand question marks in Zhou Boguang's mind. According to Lao Zhou's character, if he didn't figure out how people like him got it done, he would not be able to sleep tonight.

So Su Yuanshan smiled slightly and took out the hard drive from the briefcase.

"Professor Zhou, hello, our chip design only took about two months. The biggest contribution lies in the EDA software developed by Yuanxin, which has the strongest integrated circuit design and simulation capabilities on the market. Just Yesterday, it passed the layout compatibility test of Jiangyin Factory."

"If you are willing, I can show you our chip design functions and simulation functions on site."

Su Yuanshan built a new project.

"The operating habits of Yuanxin EDA are similar to those of Cadence, but the functions and automation level are far richer and stronger than Cadence. Our simulation tools are unique in the world, involving more than ten algorithm patents that are being applied for."

As Su Yuanshan explained, he planned the modules arbitrarily and put down the logic circuit easily.

"Because it is a modular and intelligent design, it requires high computer performance. Especially during simulation, if there are too many components, it may take a long time - but under Moore's Law, the CPU speed will become faster and faster. Come faster and faster, none of this will be a problem.”

Su Yuanshan looked back at Zhou Boguang who looked shocked, thought for a while and said: "Professor Zhou, please think of a simpler need now, and I will demonstrate it to you."

Zhou Boguang licked his lips. He was in a terribly complicated mood right now, and he couldn't think of any needs at the moment. At this time, Chen Yujie, who was also shocked, suddenly came to his senses: "You design a card reading chip for the access control switch."

Su Yuanshan was startled, then smiled: "Senior Brother Chen, this is not easy, isn't it? What kind of network do you use?"

"Internet? No need for Internet."

"Uh...I might have misunderstood. Okay, just give me the requirements and parameters."

Chen Yujie immediately ran back to the office.

Su Yuanshan did not wait for him, but planned the functional modules first.

If it was a network card reader, then he couldn't "pretend". After all, that project involved network transmission, data storage, and exchange, which was more troublesome than building a pager. He couldn't even hope to finish it in a month or two. After all, he has a mature plan for pagers.

But a simple card reader only needs to compare high-frequency signals.

As Chen Yujie brought in the requirements and parameters, and the functional modules were planned and arranged, Su Yuanshan began to compare the parameters and input instructions.

Two hours later, Su Yuanshan completed inputting the last instruction and generated the circuit at the same time. After simulating it again and correcting two bugs. Su Yuanshan set the parameters and started the simulation.

"Small chip, simulation should be fast."

As the pins light up one by one, the green parameters are also displayed. Ten minutes later, the simulation is completed in one pass.

Su Yuanshan didn't look at Chen Yujie. He was afraid that Chen Yujie's hot breath would blow into his face - this guy was standing on his right side now, panting heavily.

"Professor Zhou, what do you think of our products?"

Zhou Boguang had regained his composure, but his eyes were as bright as stars.

At the same level, what is the most important thing in integrated circuit design?

It's a tool.

Before the birth of EDA, designing chips relied entirely on hand-drawn drawings. Therefore, after the emergence of the first 4004, the MCS-48 was reproduced in China relying on hand-drawn drawings - Zhou Boguang was one of the participants.

At that time, everyone had the same design tools: paper, pen, and ruler.

When various EDA software appeared later, Intel, which had the right time and place, quickly used the convenience and convenience of major EDA to launch new instructions and design new products, and at the same time completed the patent barriers of X86.

It can be said that tools are the primary productivity in the field of chip design.

Now, the young man placed a dragon-slaying knife in front of him. Ask him how he feels?

Thanks to Xiao Xing Can Yue, Shu Xing, and Lonely Patient 11. I am really a fat man for the reward~~
