🙂 Hi.

I am Mohamed "Donn" Gaber, an EDA Tool Engineer with Efabless Corporation and developer on the OpenLane RTL-to-GDSII flow. I've previously interned as a research engineer at Microsoft Advanced Technology Labs, where I worked on speaker recognition.

I studied Computer Engineering at the American University in Cairo, where I still maintain their Cloud V platform and contribute to some research efforts such as Fault and DFFRAM.

Side Projects

  • Nudelta, a reverse-engineered open-source alternative to the console for NuPhy keyboards
  • Oak (maintenance), a browser-based assembler/simulator generator
  • Phi (inactive), a more focused take on Verilog that started as my undergrad thesis project


  • Email:
    • For inquiries about Efabless Projects (including OpenLane), please send them to my direct superior instead. Thank you for understanding. 🙂
