PatternLab vs FpgaLearn

Discover the beauty of patterns. PatternLab is a creative sandbox for exploring cellular automata — simple rules that give rise to endless complexity. Inspired by Conway’s Game of Life, PatternLab lets you draw, experiment, and watch living patterns unfold in real time. Whether you’re curious about math, love puzzles, or just want to relax and watch mesmerizing shapes evolve, PatternLab makes science playful and accessible. Features: • Multiple rule sets: Conway, Seeds, Maze, Day & Night • Pre-built patterns: Glider, Blinker, Pulsar, and more • Custom drawing tools to create your own designs • Adjustable grid size and simulation speed • Color themes including high contrast & accessibility modes • Undo/redo support for fast experimentation Why you’ll love it: • Relax and watch infinite patterns evolve • Spark creativity with mathematical art • Learn about complex systems in a hands-on way PatternLab is perfect for students, creators, and anyone who enjoys interactive experiments. Dive in, play with rules, and see how small changes create surprising results.

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.
