Chapter 589 The dilemma faced by EDA software?
Ah!
Everyone knows about EDA tools, right?

After all, everyone present is a super academic bully who is loved by everyone, flowers bloom when they see flowers, and combines beauty and talent.

(ω) hiahiahia.

Well known.

EDA is the abbreviation of Electronics Design Automation (Electronics Design Automation).

Developed from the concepts of computer-aided design (CAD), computer-aided manufacturing (CAM), computer-aided testing (CAT) and computer-aided engineering (CAE) in the mid-20s.

It can be roughly divided into three categories.

Namely chip design assistant software, programmable chip assistant design software, system design assistant software.

At present, the EDA software that has entered our country and has a wide impact is system design auxiliary software and programmable chip auxiliary design software: Protel, AlTIumDesigner, OrCAD, PCAD, LSILogic, MicroSim, ISE, modelsim, Matlab and so on.

Everyone read that right.

All of the above software comes from abroad.

It seems that there is no domestic research and development.

Ah!
Ordinary people may not understand it.

But those who know more about computers, or those who have studied computing professionally, must be very clear.

These tools have strong functions and can generally be used in several aspects. Most of them can be used for circuit design and simulation. At the same time, they can also perform PCB automatic layout and routing, and can output a variety of netlist files to interface with third-party software.

of course!

Although the above software comes from abroad, it can also be used in China at present.

but……

This is not very useful for chip design.

Because the EDA tools required for chip design refer to chip design auxiliary software, which is an important computer-aided design software in the processes of electronic chip design, circuit board layout, and integrated circuit simulation testing.

As for this software, foreign countries (mainly Dayang) have imposed certain blockade restrictions on China.

Keep it simple.

People just give you a neck.

I don't want you to have the ability to design chips yourself.

Maybe some people will ask, what is the use of this so-called EDA tool for self-designed chips?
the answer is……

This is of great use.

For example...

Just as chips cannot be manufactured without a lithography machine, chips cannot be designed without EDA software.

The former card manufacturing and the latter card design are equivalent to the two legs of chip research and development. If one is broken, one cannot walk.

Maybe some big students will ask, is it okay to use other methods to design chips instead of using EDA software?

the answer is……

Currently, no.

After all, this is the 21st century.

rather than the last century.

In the middle of the last century.

When practitioners of integrated circuits design circuit diagrams, they often use the most primitive way to draw by hand on the drawings.

However, with the rapid development of the integrated circuit industry, thousands of units are often integrated on a more complex chip, and it has evolved into a multi-level three-dimensional structure.

Drawing by hand?
Isn't that a joke?
You can't draw it by hand for a year.

So there is EDA software to realize extremely complex chip circuit design on the computer.

It's worth mentioning.

The EDA software here does not just refer to a design software, but a very large category.

In the entire chip design process, specific EDA tools are used in each link of chip front-end design, pre-simulation, back-end design, verification, and post-simulation.

Not only the chip industry, but also aerospace, communication measurement and control, and machinery manufacturing.

If chip manufacturing is compared to building a building, IC design is the design drawing of the building, and EDA software is the design tool for this drawing.

It's just that the complexity of EDA software is N times higher than that of architectural design software.

The two are not on the same level at all.

In fact...

EDA tool is not just a tool so simple, the most important thing is the automatic design of electronic products.

It's like a lithography machine.

As long as you input the instructions, the lithography machine can help you automatically produce chips.

Electronic designers can use EDA tools to design electronic systems from concepts, algorithms, protocols, etc.

And the entire process of electronic products from circuit design, performance analysis to design of IC layout or PCB layout can be automatically processed on the computer.

Putting it this way...

Everyone should understand!

Very clear and simple, isn't it?
With the development of integrated circuit technology.

EDA software is increasingly being synonymous with "chip design software tools" by the industry.

That is to say...

EDA software is an important tool for chip design.

However, due to the complex process of chip design, refined division of labor and multi-technology integration, EDA software does not refer to one or a few software, but involves nearly a hundred different technologies, covering a variety of "point tools" software tool clusters.

It can be said like this……

EDA, semiconductor raw materials, and lithography equipment together constitute the three major foundations of integrated circuits.

Even if Jiangnan has solved the problem of raw materials, it has reduced the demand for high-end lithography machines.

But if the EDA tools are not ready, the production of domestic high-quality chips is still far away.

Today's chip has at least hundreds of millions to billions of transistors, and the design process requires continuous simulation and verification, which is inseparable from EDA software.

In short, without EDA tools, no matter how high-level chip designers are, they are useless.

So much so that EDA tools.

Also known as the mother of the electronics industry.

Maybe someone will ask again...

Since EDA tools are so important in the manufacture of chips, why doesn't the country go all out to overcome them?
This question is very well asked.

What country is our Dongyun?
That is a country that likes to be self-sufficient, and has always pursued that everything can be produced by itself.

It can be useless for the time being, but you must have it yourself, and you will never depend on other countries and let others have the power of life and death.

and so……

Like lithography machines, the country began to lay out and develop EDA tools many years ago.

This can be traced back to the 80s of the last century, when more than 17 experts from 200 units gathered at Yanjing IC Design Center from all over the country.

There, Dongyun will launch an epic battle in the integrated circuit industry.

Although after 7 years of arduous research, the first EDA tool in China - Panda system was born, and Dongyun finally broke through the foreign EDA containment, and we have become one of the very few countries in the world with independent intellectual property rights of EDA.

Unfortunately……

It didn't last long.

Just when the domestic EDA tools were just ignited, countries such as Dayang, which mastered the most advanced EDA tools in the world, relaxed the restrictions on the use of EDA by Dongyun.

Because foreign EDA software is more advanced and the price is lower, and under the market pressure of packaging and dumping, domestic EDA tools are directly hit hard, and the road to commercialization is far away, so that domestic EDA will not recover for a long time.

then……

The EDA market of Dongyun was captured by foreign companies such as Dayang, and 95% of the market share was divided by the other party, while domestic EDA only occupied 5% of the market share.

and……

This situation has not been broken.

to be honest.

That is, people step fast, step by step.

Their technology is better and the price is cheaper. With their innate advantages, Dong Yun was trampled so hard that he couldn't get up.

Although after entering the new century.

Dongyun once again realized the importance of EDA, and was not willing to be controlled by outsiders, but once again invested huge human, material and financial resources to encourage enterprise research and development.

Then there are many companies such as Jiutian, based on the Panda system, and opened up an EDA road.

But in fact, there are still many problems.

Even Jiutian can only provide one-third of the software for the industry, and compared with the EDA manufacturers of Big Yang, there are still two-thirds of the tools that have not been mastered so far.

For the entire domestic semiconductor industry chain, it is difficult for domestic EDA to hold up the banner of the entire industry alone.

……
