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.
