LogicalArt vs CircuitWay

LogicalArt is a digital logic simulator where you build a computer from nothing but logic gates. Wire NOT, AND, OR and XOR gates, switch on the power, and watch every signal travel through your circuit. No breadboards, no soldering, no tangled jumper wires. Just the ideas behind how a CPU really works, made visible on your iPhone, iPad and Mac. LEARN BY BUILDING: GUIDED CHALLENGES Work up a ladder of hands-on puzzles: Half Adder, Full Adder, Multiplexer, Decoder and a 1-Bit ALU. Label your inputs and outputs, tap Verify, and LogicalArt plays the whole truth table on your live circuit, row by row, so you see exactly where it works and where it doesn't. FROM GATES TO A CPU • Four basic gates: NOT, AND, OR, XOR. Everything else is built from them. • Package any circuit into a reusable chip, then build bigger designs out of your own chips. • Create EEPROM chips straight from a truth table. • Build latches, flip-flops, registers, counters, adders and an ALU, step by step toward your own 8-bit computer. SEE WHAT YOUR CIRCUIT IS DOING • Deterministic simulation with real gate delay, so clocks, latches and feedback loops behave the way they should. • Clock inputs, number displays and a live view of every wire's state. • Waveform view to follow signals over time. MADE FOR TOUCH, TRACKPAD AND MOUSE • Drag to place gates and draw wires; pinch, scroll and zoom around large boards. • Undo, labels and a clean layout that stays readable as your designs grow. • Native on iPhone, iPad and Mac. SHARE AND DISCOVER Browse boards from other builders and share your own. WHO IT'S FOR Computer science and electrical engineering students, teachers explaining digital logic, programmers curious about what happens below assembly and Verilog, and anyone who has ever wondered how a computer actually works. FULL ACCESS Start for free. A one-time Full Access purchase unlocks every feature: unlimited boards, chip packaging, EEPROM chips and sharing. No subscription required. Enjoying LogicalArt?

CircuitWay is a SPICE simulator of analog and digital circuits. It can easily design, simulate, and analyze electronic circuits on your device. There’re 100 example circuits for your convenience to explore. They range from basic BJT amplifiers, to MOS amplifiers, to oscillators, to filters, to PMICs, to 555 timers, to switched capacitor circuits, to high frequency circuits, to basic digital circuits, and finally 10 complex projects. The 10 complex projects consist of: UART, RISC CPU, PLL, Clock and Data Recovery (CDR), SRAM, R-2R Ladder DAC, Σ-Δ ADC, SAR ADC, FIR Filter, IIR Filter. There’re 106 type of library elements in the CircuitWay, range from resistor, capacitor, inductor, to sin, pulse, pwl voltage source, to controlled source such as: VCVC, VCCS, CCVS, CCCS, to behavior voltage source, to switches, to opamps, to tranformers, to Verilog code, to standard digital cells, to ADC/DAC, to 555 chip, to Arduino and more. Because CircuitWay supports Verilog, so you can build indefinitely any number of digital circuits using Verilog hardware design language. CircuitWay can also support Arduino, so you can use c language to model a large number of complex systems. CircuitWay supports 4 type of analysis: Transient, DC sweep, AC, FFT. You can manipulate and inspect waveforms in the schematic page, and build waveform math expressions to calculate new waveforms from exist waveforms. CircuitWay is serious about helping you to understand more about circuits.
