According to a report by Sohu Tech on Thursday, Xiaomi
Some Chinese web users posted a group of comparison pictures of the Xiaomi
In response, Southchip, a high-performance analog semiconductor IC design company, officially released an article saying that the Xiaomi
Subsequently, Southchip’s response also raised some questions. Some netizens commented that Southchip, as a chip designer, lacks the ability to independently manufacture chips, let alone to become Xiaomi
According to Southchip’s official website, the firm is a China-based high-performance semiconductor design company, focusing on power supply and battery management, with R&D teams focusing on integrated circuit design, process, test technology and system applications. Its official website does not mention that the company has a chip manufacturing business.
Chip production mainly takes place in three phases: design, manufacturing/packaging and testing. A senior executive of a domestic top chip manufacturer told Sohu Tech: “In the chip industry, OEM generally refers to the manufacture phase, while OEM in the design phase is generally called ‘outsourcing.’ Xiaomi
“After the chip is designed, it still needs communication with the factory, and then tape out. The chip can be mass-produced only after it is successful,” said the source. Lin Zhi, chief analyst of Wit Display, believes that Southchip is a professional chip design company and has cooperation with wafer factories. Xiaomi
In fact, it is not uncommon to outsource some chip design work in the chip industry. With the transformation of the semiconductor industry and the higher design requirements, as early as the late 1980s, a number of chip design service companies emerged, providing complete solutions for chip design companies, reducing the cost of taping out and speeding up product listing. For example, Vivo is mainly involved in the soft algorithm and IP design during the creation of V1 chip, while the subsequent work was handed over to Vivo’s partners.
If part of the chip design work is handed over to a third party, many wonder if this chip be considered self-developed. According to the above-mentioned expert in the chip industry, it depends on whether the outsourced work is the core part, that is, it is necessary to know precisely how Xiaomi
