Summary
🤩
Rockstar🎓
Top SchoolNico Engelhardt is a CEO and researcher with 12 years of experience making FPGAs accessible as practical computing platforms, blending deep academic work with hands-on open-source engineering. He led the GraVF project during his PhD to automate distributed graph processing across multi-FPGA systems and now directs YosysHQ while contributing backend fixes and features to the widely used Yosys synthesis suite. His background spans verification, EDIF support, and test automation for RISC-V cores, reflecting a rare combination of hardware-software co-design and toolchain expertise. Based in Vienna, he has a track record of turning complex synthesis and verification problems into usable tooling and has a knack for improving obscure backend behaviors (e.g., macOS command fixes and scratchpad scripting) that materially boost developer productivity.
