Big Country Intelligent Manufacturing

The meeting room was already full of people, and Lu Guangming and Wang Changhe, who were responsible for developing the Longteng operating system, also attended the meeting.

Chairing the meeting was Zhou Jiawei, the leader of the Longteng 133CPU chip research and development group.

Seeing Xu Zhenming sitting down on the main seat, he immediately said the topic of today’s meeting: "Everyone! The Longteng EDA software has completed several internal tests. Our chipset colleagues think this software is very useful! The following work is Discuss the production of CPLD and FPGA chips!"

"There are five major elements in the research and development of the Longteng 133CPU chip, system (ASIC), communication (RFIC), modeling (MDL), microwave (MMIC) and simulation (AMS). The system has been determined, using RISC architecture. We are now the most critical The core work of the company is modeling, and the chip design project team needs a programmable logic device to support it!"

Zhou Jiawei is talking here, and a technician is operating the computer and displaying the compiled PPT file on the big screen on the wall.He asked everyone, which programmable logic device Longteng 133CPU chooses this time?

There are two types of programmable logic devices, one is CPLD and the other is FPGA.Using this tool chip, technicians in the chip development group can quickly develop, simulate and test the chip to be developed through the Longteng EDA software.

For this kind of special professional problem, Xu Zhenming is not easy to decide directly.He can only be regarded as a small professional, who can make decisions and make decisions when discussing issues and opinions are not unified.

"Leader Zhou! Which of these two chips is better?" Thinking of this, Xu Zhenming looked at Zhou Jiawei.

"Leader of the report! The development potential of FPGA chips is huge. We can now design hundreds of thousands of FPGAs, and we may have more than one million system gates in the future!" Zhou Jiawei pondered for a moment and hesitated to answer Xu Zhenming's question.In his opinion, CPLD chips will not be eliminated.

At this time, the old chip expert Wu Wen put forward different opinions: "We should make CPLD chips. We can produce this kind of chips in 1464!"

Xu Zhenming has used these two kinds of programmable logic devices.According to his thinking, the existence of these two chips is reasonable. Since these two chips will not be eliminated in the future, we will do both!

"Okay! Since the opinions of your two experts are not uniform, we manufacture a batch of both chips and use them!" Thinking of this, Xu Zhenming made the decision on behalf of Gui Changshu, the boss of the 1464 project team.

Determine this problem, the following is to discuss the EDA software BUG, ​​software to determine the version number, CPLD and FPGA design, tape out issues.

"Report team leader! Our team believes that Longteng EDA software can determine the version number of 1.0, and we find that BUG can be upgraded through plug-ins in the future!"

"Leader of the report! Which operating systems does Longteng EDA software run under?"

At this time, Lu Guangming, Wang Changhe and others spoke in succession, asking Xu Zhenming to make a decision.Their team has already started coding for the Longteng operating system, and wants to end the affairs of the Longteng EDA software earlier.

Xu Zhenming thought for a while, and believed that Longteng's EDA software should meet the computer conditions of various domestic electronics research institutes.

At present, in domestic universities, research institutes and other research institutions, UNIX systems dominate the mainstream, followed by DOS systems, Windows 95 and OS systems.In this case, Longteng EDA software should be able to run on these systems.

As for the version number, it doesn't matter if you use 1.0.If no major changes are made, the mantissa will be added to the 1.0 version number to show the difference.

"Just follow this method to determine! On December 10th, we will prepare 1,000 copies of the software, ready to be released to Beijing!" After saying this, Xu Zhenming formally finalized the details of the Longteng EDA software.

After Lu Guangming, Wang Changhe and others got the quasi-credit letter, they immediately prepared to leave the field in advance.

At this time, Xu Zhenming said again: "Your Longteng operating system must speed up! In January of 1996, we will release a beta version of Longteng operating system!"

"Yes! Team leader! Guarantee to complete the task!"

Lu Guangming and Wang Changhe gave Xu Zhenming a salute, and then left.

This side.

The content discussed at the meeting returned to the production of CPLD and FPGA.

"Report team leader! Our chip team has completed the design of CPLD and FPGA, and simulation work, the following process is tapeout and testing!"

Zhou Jiawei, who presided over the meeting, once again reported to Xu Zhenming.

The chip R&D engineers in their research group have been doing R&D work with Xu Zhenming's decrypted Cadence software and have completed the design of the programmable logic device.

"The process of chip design is generally as follows: software modeling, hardware design, hardware simulation, pre-synthesis simulation, FPGA design, layout drawing, pre-synthesis timing analysis, post-synthesis simulation, post-synthesis timing analysis, Monte Carlo analysis and production Wait!"

"The performance of the Longteng EDA software developed by ourselves is good. Colleagues have simulated and tested the designed CPLD and FPGA chip diagrams in the Longteng EDA software many times! There is no problem with the logic circuit layout! So, our current task is flow Pieces, BUG issues in the measured chip!"

Zhou Jiawei reported to Xu Zhenming the details of the chip design process, and asked Xu Zhenming which company to tape out.

Tape-out actually has two meanings, the first is the production and actual measurement of chip samples, and the second is mass production of chips.

In order to save money, Wu Wen suggested: "Report leader! We can tape out CPLD chips at 1464. Although the efficiency is a bit slow, it saves money."

"Leader of the report! My team thinks it is better to go to TI to tape out films, fast and cheap!" However, Zhou Jiawei disagrees with Wu Wen's opinion and thinks it is more appropriate to go to Texas Instruments in the United States.

Zhou Jiawei's team are all employees of Yiming Group. Most of them are chip experts who have returned from studying in the United States. They are not at ease with the chip production process of the 1464 Institute, and suggest that Xu Zhenming go to the United States to tape out the film.

This time, Xu Zhenming decided not to listen to the opinions of the two groups of professionals, but instead smiled and asked, "How about the Moss Electrical and Mechanical Company in Wanwan?"

Moss Electromechanical Company was founded in 1987 by Mr. Zhang Zhongmou.Later, it became the world's top chip manufacturer, the pride of the Chinese.But now he is not well-known, and he still can't enter the eyes of Zhou Jiawei and his gang.

"Go to Wanwan? No, no! That would expose the secrets of our 1464 project team!" Wu Wen was the first to object.

The same goes for Zhou Jiawei, "This company has no experience in chip production, and it will waste a lot of testing time!"

"Wasting time is better than going to the TI company in the United States. Going to TI may reveal the secrets of our 1464 project team! The process of 1464 can only produce CPLD chips, which is not comprehensive! So, I decided to go to Wanwantai Electromechanical Company!"

Xu Zhenming patiently explained the reasons for his decision.

At the end, he said with great emotion: "I hope this trip to Bay Bay will be the last time we have a corporate film outside!"

"Yes, Mr. Xu! As long as the 1.5-micron chip production line of our group company is put into production, we will tape out the chips in our own factory in the future!" Hearing this, Zhou Jiawei solemnly assured Xu Zhenming.

On the other hand, the cautious Wu Wen asked Xu Zhenming for instructions: "Group leader, regarding the issue of filming, I ask you to discuss with Leader Gui!"

Hearing this, Xu Zhenming smiled and nodded, took out his mobile phone and dialed Gui Changshu's number.After the call was connected, he explained the reason for his analysis to Gui Changshu.

"Okay! I agree with your opinion, we need time now! However, I want to warn you that you must pay attention to safety after arriving at Wanwan. You are now a national treasure of our 1464 group!" Gui Changshuda came from the phone. The voice of laughter.

In this case, Xu Zhenming and his party's plan to go to Wanwan can be implemented immediately.

For the sake of confidentiality, martial arts cannot be done.

Lu Qingshan, a security officer of the Changgong Group, dressed as Xu Zhenming’s assistant to accompany him and do security work throughout the process; Hu Chunmei is Xu Zhenming’s personal assistant, of course he must go with him; Zhou Jiawei is the technical person in charge, and he has installed genuine EDA software. The laptop is for the main members!

In this way, Xu Zhenming led Lu Qingshan, Zhou Jiawei and Hu Chunmei to take the afternoon plane to Xiangjiang for a transfer.At sunset, they had already arrived at the Victoria Hotel in Xiangjiang.

What surprised Xu Zhenming was that as soon as he entered the lobby of the hotel, Yang Tian, ​​the chairman of the Xiangjiang Beauty Group, followed two middle-aged men in black suits with sturdy faces to meet Xu Zhenming.

The two did not deal directly with Xu Zhenming, but invited Lu Qingshan away.

"Mr. Xu! Hahaha... Lei is good!" Yang Tian laughed and shook hands with Xu Zhenming.He was very polite to ask Xu Zhenming and others to have dinner at an outside restaurant.

Xu Zhenming has a lot of tasks, how can he do things that are out of the question?

"Dong Yang! After completing this order, you go to the mainland, how about I accompany you to Huangshan to visit?" He smiled and treated Yang Tian in a courteous manner.

Both of them are brilliant business leaders, so naturally they don't take these words to heart.

Yang Tian specially helped Xu Zhenming take the luggage and sent Xu Zhenming into his room.

When he arrived in the room, he mysteriously said to Xu Zhenming: "Mr. Xu! After you arrive at Wanwan, my guest, Mr. Yang, will personally receive you and talk about business matters!"

"Oh that's fine!"

Xu Zhenming nodded thoughtfully when he heard this.

Mr. Yang wants to see me to discuss business, which shows that the 0.6-micron chip production line is progressing smoothly!

But Yang Tian can actually know that we are coming to Xiangjiang, what is going on?

Is it the arrangement of Gui Changshu?

With doubts, Xu Zhenming sent Yang Tian out the door of the room.

"Mr. Xu! Where shall we go for dinner tonight?"

At this time, Hu Chunmei, who had gone through the procedures for ordering air tickets, came to ask questions.

Hu Chunmei is having a great time now. Without Yang Ting, a competitor, the sense of crisis in her heart is much less.

She stood near the door of Xu Zhenming's room with a slightly flushed cheek, and was not embarrassed to walk in.

It is inconvenient to be alone.

Hearing her question, Xu Zhenming picked up the phone in the hotel and called Zhou Jiawei, asking him if he wanted to go out for dinner.

However, Zhou Jiawei said: "There is room service in the hotel, let's eat in the room! I will review the chip design tonight!"

In this case, Xu Zhenming decided to keep things simple!
