Software engineers have platforms like LeetCode to practice algorithms and prepare for interviews, but hardware engineers (RTL, digital design, embedded systems) don’t really have an equivalent place to practice.

So I built a platform where you can solve hardware challenges directly in the browser.

Right now it includes:

• 51 RTL problems with an online Verilog simulator • 51 circuit analysis / design problems with simulation • 101 embedded C challenges • waveform visualization for RTL simulations • a forum where users can discuss solutions • the ability for users to create their own challenge or interview questions

In total there are about 200+ problems so far, and around 400 engineers have already signed up.

One thing I found interesting is that many engineers want to share interview questions or tricky design challenges from real hardware jobs (FPGA, ASIC, embedded), so the platform allows community-created challenges as well.

Everything runs directly in the browser using a backend simulator infrastructure.
