The trend of downstream industries to chip design fields has made downstream customers launching competitive products while reducing their own chip procurement, which has brought certain competitive pressure to the existing chip design manufacturers. However, from the perspective of the chip classification The self -developed products are mainly concentrated in the field of digital chips.
From the perspective of public reports, the types of self -developed chips in the downstream industry are mainly digital chips, such as mobile phone SOC, image processing chip, cloud computing and AI chip. Digital chips generally have the characteristics of large size, high unit price, fast update, and relatively single model. Take mobile phone SOC as an example. The typical price of a single chip is about $ 100, and the number of mainstream mobile phones that coexist in the industry in the industry is very small. For example, Apple's A series processor, Qualcomm's Snapdragon series processor, Huawei's Kirin series processor, etc. Therefore, the sales of single chips are huge.
The type of simulation chip is very complicated. Only Texas instruments have more than 80,000 simulated chip models, and the shipments of single chips are small. The product characteristics of the simulation chip make the downstream terminal manufacturer more difficult to enter the field of simulation chips. The main reasons include:
(1) The design of analog circuit design needs to be considered between various factors such as speed, power consumption, gain, accuracy, power supply voltage, noise, area and other factors. Digital circuit design needs to balance between three factors: power consumption, speed and area. Essence
The design of the digital chip is mostly automatically generated by using the hardware description language with the basic logic door circuit with the assistance of the EDA software. The requirements for logic and algorithm are high. Consistency.
The design of the simulation chip is mainly through the design and simulation of the crystal -level circuit design and the corresponding layout design and simulation by simulating engineers. It often does not have an absolute optimization path, so it has higher experience in simulation engineers. Digital chip design can often shorten the R & D time to a certain extent by increasing investment in funds and personnel. However, during the design of the simulation chip design, the increase in R & D personnel has a limited role in R & D progress in single products.
(2) There are many categories of electronic devices on the category of simulated chips, but the use of single chips is small. The above characteristics make it difficult for downstream customers to achieve the development of the all -category simulation chip they need. Mimic chip is usually a more economical choice.
And the operating management cost required for a single simulation chip in the process of manufacturing is the same as digital chips. In this case, the huge difference between the chip price and usage amount makes the income from downstream customers' investment in the simulation chip is far lower than lower than that Digital chip.
In short, the extension of downstream industries to chip design is mainly concentrated in the field of digital chips. The design characteristics and complicated categories of simulated chips make downstream customers extend to the field of simulation chips.
