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 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. Your code is compiled and simulated on our servers, and within seconds you get the waveform, a synthesis report and your grading results back.
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.
