Lu's Sifang Industrial Company, R&D Center Laboratory.

Yu Zixian didn't have time to say hello: "Liu Jian, have you finished sorting out the chip information last time?"

"Isn't our new two-piece movement finalized? ”

"What I asked about was the internal data of Toshiba's remote control chip TM50536 that is, the netlist circuit diagram and the analysis of the internal structure after the chip layout data conversion was completed. ”

"After the optimization design of the new movement is completed, don't we want to further optimize the remote control circuit, there are enough experimental instruments here, and with the help of the master, the progress is surprisingly fast!"

"Ah, yes, yes, so where did you end up?"

"With the help of Lu's side, we have carried out many redesigns and optimizations on CAD (computer-aided design), and there should be no big problems, but if we really want to verify its layout design and logical feasibility, we also need to test it on more advanced EDA (electronic design automation software), as long as there are no errors in EDA, the chip can be regarded as a preliminary design success. ”

After layout design, post-simulation of the layout is also required to verify and optimize post-migration errors and performance such as timing and power consumption.

"Hehe, Liu Jian, you have made great progress, you know EDA. ”

"Uh, this is what Director Wei of the laboratory said, I didn't know what EDA was at the beginning, so I asked hard, and he explained to me that it is a more advanced electronic design automation software than CAD, and they have it in the comprehensive laboratory in Xiangjiang. He also said that if we have the chance, we can also try out what it's like to design on EDA. Auto-generated, so cool......"

"Why didn't they see them last time I visited their lab? "These advanced technological software are generally restricted or strictly censored for export, especially in relation to the Republic and the regions associated with it. And now that Lu's Group has the Xiangjiang Semiconductor Laboratory, it seems that their relationship is not ordinary.

Yu Zixian found that this was an excellent opportunity, but he didn't know if it would be in time, but he had to try, otherwise according to the current situation in the Quartet, he could only be slaughtered.

Originally, he thought that the current Quartet had embarked on his own path, but as a result, such a drama came, all of which pointed to the key core of the chip. However, whether it is the design or manufacture of chips, it can be done by very people. Not only does it need a lot of money, but it also needs a lot of human resources to support, which is why he has been unable to start for a long time.

"Liu Jian, you collect, sort out and pack all the information about the TM50536 chip, then take your passport, pack your luggage, and wait for the next arrangement. ”

"Ah, you're going to Xiangjiang?!"

"Well, I'm going, I'm probably going to leave in the afternoon. ”

After Yu Zixian finished speaking, he immediately turned to the office of Director Wei of the experiment.

"Please come in. After knocking on the door twice, a voice came from inside the office.

"Hello Director Wei. I came here to find you with comments on very important matters, and I hope to help you contact and communicate and coordinate. ”

"Well, you speak first. Wei Xianglin looked at Yu Zixian with a serious face, not like a joke.

"The main material of the remote control circuit board in our joint venture factory chip has been out of stock, you know this, right?"

"It's out of stock? I haven't heard about it yet. But it shouldn't be, the current agent supplier has cooperated with us for many years, and generally will not easily destroy the cooperation, and I used to make some of the latest models of chips through them. ”

"Well, Director Wei can contact your headquarters or ask Manager Li for relevant information later, and you can verify it. That's what I'm here for. ”

"Say it. ”

"Liu Jian is now doing remote control circuit design and optimization, and at the same time doing the internal data extraction and optimization design of Toshiba's TM50536 chip, which I think Director Wei knows. ”

"I know this thing, and we often use reverse design, so this is nothing?! But I support him, and I also did some post-chip optimization guidance. ”

"As I said, he was on a very fast pace and it was done in two or three months. But it just so happens that we need to simulate and verify the layout of it now, and we don't have EDA software here, so I want to take it to your headquarters in Xiangjiang. ”

"Go to Xiangjiang to EDA?"

"yes, the sooner the better?"

"In such a hurry?"

"I want to make our own TM50536, but when the time comes, I won't be called that. Because we have also optimized the design of it. ”

"Impossible, even if you go to EDA, you may not be able to mass produce!? Besides, it's too late to get ...... time? Generally, after EDA, you have to tape out, and it takes a month or two to tape out; there is another problem that you can't avoid, that is, the authorization of the patent license production of chips, you are infringing, Toshiba will sue you, and it will then."

"It's okay, as long as it can be made, they have lost the biggest basis for cutting off the supply, and I can guarantee that they will not sue. ”

At present, the core of several chips used in remote control chips is Toshiba's exclusive supply of TM50536, which is also the reason why they are directly out of stock. The others are produced by Mitsubishi or other factories, and they are highly replaceable, so Yu Zixian found the same type of chips from other factories to replace them, but it was just a matter of cost performance.

"Regarding the question of time, we don't need to go to the foundry to tape out, we just need to make it. So there should be no problem with timing. What's more, this chip has template information, and we will modify it much faster, as long as the EDA can be successful, the manufacturing is very likely to be successful at one time. ”

"I believe that every employee of the joint venture factory does not want Toshiba's monopoly and suppression to lead to the bankruptcy of the joint venture factory. So we need everyone's cooperation!"

"Hmm. Wei Xianglin nodded solemnly. Now as a member of the joint venture, her own benefits are indeed linked to her benefits. And he himself is also very optimistic about the inland electronics market, so he will set up a technical team of the joint venture factory as the technical leader of Lu's Semiconductor, otherwise how good the living conditions in Xiangjiang are, why come here? !

"I'll report to Manager Li and report to the Xiangjiang headquarters. ”

"Okay, I'll come back to you later! I hope we can leave for Xiangjiang in the afternoon." ”

Convincing Wei Xianglin means that Yu Zixian has taken the first step with difficulty.

The next thing depends on the accuracy of the layout data of the TM50536 chip. However, Yu Zixian is also confident that if the movement optimization is counted, this is the second practice.

It's time for Yu Zixian to go to Director Luo.
