FpgaLearn vs MathMind.am

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. No ads, no subscription, no account. PURCHASE Unlock Full Course is a one-time purchase, not a subscription, and supports Family Sharing. Restore it anytime from the Me tab. Buyers of version 1.0.5 or earlier keep all content automatically.

MathMind gives students in Armenia the complete worked solution to every problem in the official mathematics workbooks (shtemaran) used to prepare for the national unified exams — not just the final answer. Find any problem by its four numbers — part / chapter / section / problem — and the app opens the full solution: the statement exactly as printed in the workbook, every step with an explanation of why it is taken, all sub-questions solved separately, the drawings where the problem has them, and the verified answer. Mathematical notation is typeset properly, the way it looks on paper. WHAT IS IN A SOLUTION • The problem statement, complete, in the workbook's own wording • The steps with explanations — the why, not only the what • Every sub-question (a, b, c) worked out separately • Geometric drawings rendered inside the solution • The checked answer, on the same screen HOW SEARCH WORKS Enter four numbers — part, chapter, section, problem — and tap search. For example, 1/2/3/4 opens problem 4 of section 3, chapter 2, part 1 together with all of its sub-questions. SUBSCRIPTION Access is sold as a non-renewing subscription for 1, 3 or 6 months. Nothing renews automatically and nothing is charged again when the term runs out: the purchase adds days to your account and you decide whether to add more. Every plan gives the same access to all solutions, with a limit of 30 problem lookups per day. Access belongs to your MathMind account, so signing in on another device brings it back. The app's interface and all solutions are in Armenian. Questions: support@mathmind.am
