FpgaLearn vs Kawn

A complete FPGA starter course in your pocket. FpgaLearn takes you from logic gates to state machines, bus protocols, timing constraints and board bring-up. Write code and see the waveform instantly; grading checks circuit behavior, not code style, and points to the first mismatch when something is wrong. START FREE • Stage 1, Digital Logic Basics: all 10 lessons free • Beginner exercises, the logic gate lab, the Verilog playground and a 303-entry concept wiki are always free • Unlock the full course with one purchase when you are ready THE FULL COURSE • 42 lessons in 4 stages: digital logic, Verilog, hands-on projects, then FPGA architecture, timing constraints, toolchains and HLS • 28 auto-graded Verilog exercises across combinational and sequential logic, FSMs, arithmetic and UART/SPI/I2C, at beginner, intermediate and advanced levels • 54 lesson quizzes with spaced review and a wrong-answer log WHY IT WORKS • Real four-state simulation (0/1/X/Z): a forgotten reset shows up as red X on the waveform • Behavioral grading: any correct implementation passes; failures jump to the first mismatch on the waveform • Tap-to-repair: practice the key logic without typing whole modules on a small screen • Learning map: prerequisites across 303 concepts and 42 lessons at a glance • Bookmarks and personal notes OFFLINE AND CLEAN Lessons, simulation and grading all run on device.
