Built for engineers who think in logic.
Codiode is an online learning platform designed for hardware and digital design engineers. We offer interactive circuit-building problems (LOGIX environment) and RTL coding challenges (Verilog, SystemVerilog and VHDL) with real-time automated grading, so engineers can practice and sharpen their skills at any point in their career.
What we do
Codiode provides two core problem-solving environments:
- LOGIX: a visual drag-and-drop circuit builder where you wire up gates, flip-flops, and combinational blocks to solve digital design problems. The simulator evaluates your circuit against hidden test vectors and gives immediate pass/fail feedback.
- RTL: a browser-based Verilog, SystemVerilog and VHDL editor backed by a real simulation toolchain running on our servers. Submit your HDL code and receive waveform output, synthesis reports, and grading results in seconds.
We also offer a structured skills track, community discussions, weekly contests, and a Pro subscription tier that unlocks advanced problem sets, detailed solutions, and priority grading.
Our mission
Hardware design roles demand practical hands-on skill, yet most learning resources stop at theory. Codiode bridges that gap by giving engineers a realistic, tool-driven environment where every problem mirrors the kind of work done in ASIC, FPGA, and verification teams at top semiconductor companies.
