From December 22 to 23, at the 2021 annual conference of China’s integrated circuit design industry and Wuxi integrated circuit industry innovation and Development Summit Forum (ICCAD 2021), Dr. Yang Yi, general manager of socienext China, was invited to deliver a keynote speech on reshaping the silicon-based platform for people’s travel mode, which introduced in detail the core IP of socienext in the field of network application With the design capability and experience of large-scale SOC, facing the development of the current hot emerging electric intelligent vehicle industry, as a core chip supplier, I hope to empower this industry that is reshaping people’s travel mode with the mature vehicle specification silicon-based platform capability of socienext.

The history of automobile development is the history of changes in people’s travel and lifestyle

The continuous innovation and breakthrough of science and technology will continue to promote the continuous iteration, evolution and upgrading of the automobile industry; The automobile industry also promotes profound changes in all walks of life such as city, society and energy, as well as people’s travel and lifestyle. The wave of intelligence has ignited the third revolution in the automobile industry and people’s travel mode.

The automobile industry is evolving from the traditional automobile era to the automatic driving era. Technologies such as electrification, intelligence and networking of automobiles are rapidly landing and deploying. The government and capital are also deeply involved. To a certain extent, they have played a role in boosting the development of automatic driving.

Development trend of automobile industry: Transformation of E / E architecture

Automotive electronic and electrical architecture (E / E) is evolving from the architecture of distributed ECU to sub domain computing and centralized computing in the future. More user-friendly cockpit experience, more sensors with higher accuracy, and communication requirements with larger bandwidth need to be carried by computing power chips with stronger computing power. This puts forward higher requirements for the integration of computing platform and SOC in the vehicle. It can be seen that the computing SoC platform has become the core of AD / ADAS and intelligent cockpit.

The first change is the transformation of E / E architecture

In the traditional distributed architecture, there is no concept of E / E architecture. The system is maintained by hundreds of ECUs that need to be optimized separately. However, as the vehicle control becomes more and more digital, the interconnection of ECU is more and more. Domain architecture is used to outline and define the whole system.

The domain architecture allows effective data transmission within the domain and reduces the wiring harness, but because it may be dispersed in different areas of the vehicle, a partition architecture is adopted to achieve a more efficient architecture. In the regional architecture, each region contains a part called regional controller (or regional gateway), which controls data communication, high load process and the whole system control are integrated in the central vehicle computer.

With these changes of E / E architecture, the requirements for higher performance semiconductor SOC are higher and higher. The on-board computer requires CPU performance of more than 100kdmips and cognitive performance of more than 100tops.

Socionext’s target automotive segment (MS) mainly includes sensing edge, cockpit HMI and automotive computing. Sensing edge is a sensing system to detect the external state of automobile. Socienext focuses on the field of lidar. Cockpit HMI is a human-computer interaction interface, in which the vehicle display system, and socienext focuses on the display controller. Automotive computing is an autonomous driving / ADAS domain architecture and partition architecture system. Socienext focuses on surround view monitoring and partition / HP computing.

In addition to more than 20 years of experience in the automotive market, socienext has rich and diverse technical know-how in system development, such as low-power, large-scale, high-speed and high-performance design. Its fields include consumption, network, data center and industrial market. In order to adapt to the changes in the case era, socienext has the ability to evolve the existing automotive SoC development mode using the old process technology into a new mode with automotive SOC as the flagship and advanced process technology.

Secondly, the SOC design technology of socienext

In 5g, data center and automotive markets that require advanced SOC, SOC architecture has been changed to similar architecture configuration due to the increase of required specifications (such as computing and network). As an independent semiconductor company, socienext has a broader vision of market applications. It can use its own advantages rather than the semiconductor components required by specific products in the vertical integration model to provide a more competitive SOC. In addition, through a flexible IP portfolio, including IP from other companies, we can quickly respond to customer needs and develop flexible ASICs using basic SOC architecture technology.

With rich SoC design experience, soiconext can provide highly competitive SOC for the automotive market.

Socienext advanced process initiative: Traditionally, in order to ensure the quality of vehicles, automotive semiconductors are usually developed using backward generation process technology. In recent years, due to the changes of electric vehicles and E / E architecture, it is essential to realize large-scale, high-performance and low-power advanced technology in the automotive field requiring computing resources, and there is also a demand in the market when other advanced technologies are needed. This trend is significant in the field of AD / ADAS. Although socionext is currently developing 5nm SOC, it needs advanced 3nm process development in the future.

The advanced technologies of socienext can be divided into three categories: the first is hardware technology. Socienext provides SOC architecture, system integration and IP technology to develop specs in ASIC. The second is software technology. Socienext has software engineers and technologies from low-level to high-level. Finally, automotive quality assurance. The rich development experience of socionext team supports the product to comply with iso26262 / iso21434 functional safety system.

Through these three elements, socienext can provide SOC solutions using automotive quality hardware and software technology. Socienext provides automotive quality hardware and software technology for SoC solutions to meet customer needs.

Socienext ensures higher quality and reliability of vehicles through the following links:

Design strategy (DFM / DFT)

Test strategy

Reliability test (aec-q100)

Production process control (automotive service package)

Functional safety system (iso26262)

Customer complaint (8D report)

Socionext can be used to customize the IP of SOC, and can effectively combine these IP with third-party IP to provide system optimization solutions for customer needs.

Omniview is a software library for surround view monitoring system, which is a technology to synthesize multiple camera images and display them from a free viewpoint.

For 2D graphics IP, socienext is preparing 2d-blt processing function, jitter / clutter display function and video capture function to control camera video input as the IP of display controller.

ISP + AIIP is a high-precision image recognition IP. ISP IP and AI engine are used to accurately reproduce the image, so as to achieve the best performance according to the requirements of monitoring and detection. This is the technology to achieve high image recognition performance in the future artificial intelligence engine.

High performance and high precision analog IP is a highly reliable IP. Silicon demonstration and mass production are realized in ADC / DAC.

For low-power technologies, we have technologies to suppress and control the power consumption of components such as clock, power control, standard unit and SRAM.

At the end of the speech, Dr. Yang Yi concluded that the growth of the automobile market, especially the growth of the ASIC market, provides a great opportunity for sustainable development for socienext. Socionext provides customers with high-quality and high-performance customized SoC platform with strong front-end expertise, exquisite 7Nm / 5nm design and implementation skills and advanced in vehicle IP. In addition, socionext has extensive knowledge in the automotive field, especially in functional safety, making it a leader in the independent field; In addition, the rich partner ecosystem enables socienext to expand the market scale and accelerate the time to market with IP partners.
