How Capable is Kubuds Technology in the Emulator Field?
Highly capable. It ranks among the top in China but remains less known internationally. This year, the company has been making efforts to go global, including joining the RISC-V International Foundation and completing the QEMU project for the OpenHW Group.
Although, counting from October 2023, Kubuds Technology has been established for less than a year, its co-founders already possess over five years of practical experience with open-source emulators like QEMU and Spike.
Before founding Kubuds Technology, co-founder and CEO Li Weiwei served as the leader of the PLCT Lab’s emulator team. Under his leadership, the team completed the design and implementation of multiple RISC-V related extension instructions. All related work was conducted openly and can be viewed and used in the official QEMU [1] and Spike [2] repositories, as well as in the PLCT Lab’s open-source project repositories [3-4]. Regarding commercial delivery, Li Weiwei’s team, representing their institution, undertook several emulator-related projects for leading chip and internet companies over the past five years, achieving on-time, high-quality delivery for all, and securing derivative project commissions from these leading enterprises for three consecutive years.

Some public code submission records (Reference [2])
Li Weiwei also actively engages in domestic public emulator training and technical sharing. The course “Emulator Development from Scratch,” created in collaboration with another co-founder, Wang Junqiang, has attracted over 30,000 viewers to date. (Compared to courses on operating systems or compilers, the audience for emulator topics is still relatively small. Furthermore, content deeply exploring the implementation of RISC-V extensions within the QEMU framework was scarce at the time, making Li Weiwei and Wang Junqiang’s public course a valuable supplement.)
In terms of talent development, over the past five years, Li Weiwei has trained numerous interns and new employees. Through public lectures and similar formats, he has attracted over a thousand participants to learn and engage in the development of projects like QEMU, Spike, and Sparta.
Kubuds Technology will begin rolling out a series of internship positions [6] starting in April 2024, including directions such as the aforementioned QEMU and other emulator development. All internships are remote, requiring contributors to use their personal email and name to contribute code to internationally renowned open-source communities.
