Summary
👤
Senior🎓
Top SchoolYihong Chen is a technical leader based in Beijing with nearly two decades of experience designing and improving circuit simulation and chip macromodeling tools for companies like Synopsys, Huada Empyrean, and Greatalent. He blends deep domain expertise in SPICE/Fast SPICE, mixed-signal and post-layout simulation with hands-on engineering and customer-facing product leadership, often translating complex customer requests into prioritized roadmaps and on-site integrations. At Greatalent he built a reliability platform around the Saber simulation tool and continues to consult on chip macro models, demonstrating a practical focus on product reliability and toolchain interoperability. Beyond EDA, he contributes to open-source projects in computer vision and annotation—implementing Deep Feature Flow in a CVPR2020 codebase and fixing Three.js-related issues in the widely used Scalabel annotation tool—showing versatility across ML and full-stack development. Known for bridging research, product, and engineering teams, he combines academic roots in navigation and automatic control with a pragmatic track record of shipping performance and integration improvements.
