Chapter 53 50: The true value of eda

Although Han Chen didn't take the two of them for supper after the meal, he still took them to a busy place.

During this process, Zhou Yingling felt that she was redundant. If she had known better, she would not have traveled all the way to Shenzhen with Gulina.

Gu Lina and Han Chen, two handsome men and beauties, also attracted countless people's attention.

At eleven o'clock, Han Chen drove the two girls back to Han's Manor.

"Husband, I want to go to Disneyland." Gulina said.

"Then I will ask someone to apply for your visa tomorrow." Han Chen said.

Zhou Yingling was sitting in the back seat with an envious look on her face, wondering if she also wanted to find a boyfriend.

Returned to Han Manor at [-]:[-].

After returning to the manor, the three of them took the elevator to the third floor and returned to their respective rooms.

Fortunately, Zhou Yingling was able to fall asleep as soon as she lay down.

But for Gulina, it is inevitable that there will be another battle tonight.

December 2009, 4.

am: 08:30
After getting up, Han Chen pushed Gu Lina in his arms.

"Get up at dawn." Han Chen pinched her nose and said when she didn't respond.

"I don't want to get up, I still want to sleep." Gulina replied in a daze.

Han Chen didn't care that she went to the bathroom first, took a shower, changed clothes and went downstairs.

cough cough.

Maybe it was because the two of them had too much fun last night, but Gulina was too tired and didn't want to get up at all.

The fight between the two last night lasted until three o'clock.

It is normal for young people to be youthful and energetic.

Han Chen is not worried that he is young and does not know how precious sex is, and that he will shed tears when he is old.

Because he believed that it would not be long before the system would produce genetic medicine.

Han Chen smelled a scent when he came to the living room on the first floor.

Shi Ming's mother cooked a pot of sashimi porridge.

"Shi Ma, today's porridge tastes so good," Han Chen said.

"Miss Gu, haven't you woken up yet?" Shi Ming's mother asked with a slight smile.

"She still wants to sleep in," Han Chen said.

After speaking, Han Chen picked up the phone hanging on the wall and dialed the number in Zhou Yingling's room.

"beep beep beep"

"Hello."

"Sister Ling, come down for breakfast."

"Ok."

After hanging up the phone, Han Chen sat down at the dining table and ate fried dough sticks.

Shi Ming's mother served Han Chen a bowl of porridge.

Shi Ming's mother bought the fried dough sticks from a breakfast shop outside.

Ten minutes later, Zhou Yingling came down the stairs. When she came to the restaurant, she only saw Han Chen and Shi Ming's mother.

"Brother Chen, hasn't Nana gotten up yet?" Zhou Yingling asked.

"Sister Ling, she is still sleeping in. Come over and have breakfast. This porridge is Shima's signature breakfast." Han Chen said.

"Okay." Zhou Yingling replied.

Then she sat next to Shi Ming's mother, who gave her a bowl of porridge.

am: 08:54.

"Sister Ling, if you are bored, you can go to the living room and watch TV. I have some things to do here.

We'll see how to arrange it after Nana gets up. "Han Chen wiped his mouth and said.

"Okay." Zhou Yingling nodded.

After Han Chen came to the study room, he continued to check the relevant information of EDA software.

Unexpectedly, the phone rang just as I sat down.

[Caller: Chang Huazhang]

"Mr. Han, do you have any work to arrange today?" Chang Huazhang asked. "Come over to my house. I have some IPs that you need to register." Han Chen said.

The reason why the three major EDA manufacturers are so awesome is not only because of their powerful software.

There is something very important.

This thing is ip.

This IP is different from the IP everyone knows.

IP core refers to a functional module that has been verified in the field of integrated circuit design, can be reused, has a certain function, and has independent intellectual property rights.

The IP core can be reused in other chip design projects that include the circuit module, thereby reducing the design workload, shortening the design cycle, and improving the success rate of chip design.

The mature design of these circuit modules embodies the designer's wisdom and reflects the designer's intellectual property rights.

In the early days, IP core reuse also existed in the form of internal self-use, with chip design manufacturers accumulating IP cores internally for use in different chip designs.

By the late 20s, the commercial IP core licensing model began to take shape, and some small companies began to sell logic simulation models written for simulators and emulators.

The eda purchased by Han Chen from the system came with more than 7000 IPs.

The IPs that the three EDA manufacturers have are available in this EDA, and the IPs they do not have are available in this EDA.

These IPs perfectly bypass the IPs of the three major EDA manufacturers.

The system is very careful to classify the ages of these IPs, so that Han Chen does not have to take them all out at once.

You only need to register these IPs one year in advance by year.

After this period of research, Han Chen discovered that in addition to selling software, IP licensing is also a good profit point for EDA.

The main function of IP is to allow customers to design the desired CPU faster.

But if customers want to use IP, they have to pay the manufacturer. If they don't use it, they can only design it themselves.

But in most cases it may infringe other people's IP patents.

Therefore, most designers will choose to use other people’s IP patents.

If it is a basic IP core, it is not expensive. For research purposes, you only need to pay a few hundred dollars. If it is a more complex IP core, it will be more expensive.

The general fee is 2%-3%.

The 2%-3% mentioned here is not a percentage of profit but a percentage of selling price.

It's a pity that the system sends basic IPs and not complex IPs.

What is complexity IP?

For example, the armv series that arm is selling is complexity ip.

The basic IPs that come with eda are audio decoding, video decoding, communication, or some designated computing programs, etc.

Don't underestimate these basic IP cores.

Complex IP cores are designed through these basic IPs.

To put it bluntly, the IP core is like a formula.

After Han Chen understood these things, he realized the value of this EDA software.

Nantian Software Park.

After Zhang Hengzhi came to the company, he received a message from Wang Lijun from Penguin.

Wang Lijun: Brothers, we have developed the P2P communication module you want.

Zhang Hengzhi: Come over to our company.

Wang Lijun: No problem.

After Zhang Hengzhi posted the reward, Wang Lijun contacted him through Penguin, although Wang Lijun did not identify himself.

However, Zhang Hengzhi revealed his identity, and Wang Lijun said that he was also in the Shenzhen Stock Exchange.

Later, Zhang Hengzhi negotiated a transaction method with Zhang Hengzhi.

Both parties sign a contract before testing whether the module is feasible.

Once Deep Blue Network confirms the use of the modules they developed, Deep Blue Network will pay the fees they deserve.

If the trial results are suitable but the other party's module is not used.

Deep Blue Network will pay a development fee of 3000 yuan.

The reason why Zhang Heng did this was to fish and poach talents.

So Zhang Hengzhi reached an agreement with six groups to sign a preliminary cooperation contract.
