Muqing Liu
Module Design Engineer at Apple
San Jose, California, United States
Summary
🤩
Rockstar🎓
Top SchoolMuqing Liu is a module design engineer with a PhD in electrical and electronics engineering and five years of industry experience building AI hardware accelerators, secure silicon primitives, and test automation. They have designed and verified RTL for MLP, LSTM, and CNN accelerators and implemented pipelined LSTM ASIC architectures while contributing embedded PWM RTL improvements to the high-profile OpenTitan root-of-trust project. Muqing’s work spans hardware security—developing SRAM PUF methods and an eFlash-based counterfeit-IC sensor—to lab and wafer-level characterization with extensive test automation in C/C++ and data analysis in Python, Matlab, and R. Currently at Apple and previously at Western Digital and IBM, they bridge research-grade innovation with production-focused engineering. An uncommon strength is combining deep device-level experimentation (3D NAND readout, neuromorphic cores) with practical embedded firmware and RTL fixes that improve manufacturability and security. Based in San Jose, they excel at turning complex academic research into verifiable silicon and robust test flows.

Contributions summary:Muqing primarily contributed to the PWM (Pulse Width Modulation) module within the OpenTitan repository. Their work involved implementing PWM RTL (Register Transfer Level) code, specifically focusing on standard blink and heartbeat modes. They addressed reported issues, updated register implementations, and fixed duty cycle issues, demonstrating a focus on hardware-level control and embedded systems. The user also worked on fixing some lint errors and refactoring some existing code to enhance the project's overall quality.
