Monopolized by foreign capital EDA technology , Realize the independent control of domestic chips , Domestic technology has broken through ！
I think you all know recently , The manufacture of chips depends on the lithography machine , Especially the high-end process EUV lithography . But it's just a critical step in chip manufacturing . In the process of chip manufacturing , Image lithography machine 、 Etching machine 、 Ion implantation 、 Wafer cutting equipment is an indispensable chip production equipment .
China's chip industry is relatively weak , But it's not only reflected in lithography and other equipment . We need to know the R & D and design software used by domestic chip design enterprises , It's often foreign EDA Software . and EDA Software is known as “ The mother of chips ”. There is no one's own EDA Design software , It's bound to be “ thetime ”.
At the same time , China has realized that the development of chip industry should start from all aspects . To design software from a chip 、 Raw materials and semiconductor equipment, etc . If it's hard to design chips , So design EDA Software is more difficult . The Ministry of industry and information technology also announced that , We should not only focus on supporting industrial software , We also need to make our own brand of industrial software stronger and bigger .
Let's talk about the chip design software today EDA
What is? EDA？
?1、 Actually EDA Is a kind of computer-aided design software , Used to complete VLSI （VLSI） The functional design of the chip . And synthesize 、 verification 、 physical design （ Including layout 、 wiring 、 Territory 、 Design rule checking, etc ） And so on .
?2、EDA Referred to as : Electronic design automation （ Its English abbreviation is :Electronic design automation）
?3、EDA It's the upstream of integrated circuit design 、 The most high-end industry , At the top of the chip industry pyramid , go by the name of “ The mother of the electronics industry ”.
?4、 The design of any integrated circuit is inseparable EDA Software .EDA Software can realize from simulation to layout 、 From front end to back end 、 From analog to digital, etc . so to speak EDA Software plays an important role in IC design .
?5、EDA The software design process mainly includes ：
- Hardware description language (HDL) Input
- Logic compilation 、 Simplification and segmentation
- Circuit synthesis 、 Optimize 、 Layout and wiring
- Circuit simulation
- Data generation
EDA The pattern of the industry
1、EDA Technological development
so to speak EDA Design software plays an important role in the whole IC industry chain . without EDA Software , You won't be able to talk about chips .
? In the 1950s ,IC At the beginning of Industrial Development , Mainly manual wiring .
? By the 1970s , With the improvement of chip integration design level , Manual wiring has been unable to meet the design requirements , therefore EDA Software applications .
? stay 20 century 90 years , As the number of transistors increases in IC Design ,EDA Software is developing rapidly , Widely used .
2、 In our country EDA The development of software industry
?1986 year , China's independent research and development of integrated circuit CAD system —— Panda system .
?1993 The first set made in China in EDA The panda system came out .
? Current domestic EDA Software manufacturers mainly include Huada Jiutian 、 Guangliwei 、 Generalized electron 、 Xinhe Technology Co., Ltd .
3、 The global EDA Market structure
In the world EDA In the market structure , Mainly by Candence、Synopsys、Mentor Graphics Monopolized by three American companies ; Occupying the world EDA In the market 95% share .
And our country EDA The localization rate in this field is only 5%, The vast majority of the market is controlled by foreign capital .
The strongest chip design enterprise in China —— Huawei Hisilicon
Everybody knows , The rise of Huawei's mobile phone brand is still inseparable from its powerful chip design ability . Huawei Hisilicon designed 5 Nano Unicorn 9000 chip , Its superior performance makes Huawei's mobile phone business into the top five in the world , And realized the development of its high-end mobile phone brand .
But even so , Chip design in China is still controlled by others , According to the information released by Huawei Hisilicon , Hisilicon designs chips using EDA Software comes from Synopsys（ New thinking technology ）、Cadence（ Kaiden Electronics ） and Mentor（ Mingdao ） These three American companies .
domestic EDA Technological breakthrough
domestic EDA Good news again ！
?1、 According to media sources : stay 5 month 14 Japan , At home EDA Enterprise core and semiconductor technology （ Shanghai ） Ltd. announces , On chip passive electromagnetic fields （EM） The simulation suite has been successfully approved by Samsung wafer factory 8 Nano low power consumption （8LPP） Process technology certification , This certification will significantly improve IC Design company in 8LPP Design delivery speed in process .
And this tool , In the field of passive electromagnetic simulation, it has been able to solve the domestic advanced process 8nm And the simulation design of the above process .
?2、4 month 25 Japan , At the opening of the fourth digital China Construction Summit . China EDA Leading software enterprises —— Huada nine days , Officially released EDA Tool system V2021.3 edition .
According to the official introduction , This version optimizes hundreds of complex algorithms , Can make the product function 、 Performance and capacity have been improved . The software can not only support the design of chip manufacturers in China 、 production 7nm chip , And support 28nm Mature process chip design .
The current development trend of chip industry , From design to manufacturing , There are certain difficulties . But we all have to plan for the long run , Realize industry 、 resources 、 The advantage configuration of talents . We should make use of the domestic advantages to make up for the lack of China's chip industry chain .
