List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
The most well known analog simulator is SPICE. Probably the best known digital simulators are those based on Verilog and VHDL . Some electronics simulators integrate a schematic editor , a simulation engine, and an on-screen waveform display (see Figure 1), allowing designers to rapidly modify a simulated circuit and see what effect the changes ...
Quite Universal Circuit Simulator (Qucs) is a free-software electronics circuit simulator software application released under GPL. It offers the ability to set up a circuit with a graphical user interface and simulate the large-signal, small-signal and noise behaviour of the circuit. Pure digital simulations are also supported using VHDL and/or ...
Non-linear components are represented as piecewise-linear, or as a function (simulated with one step delay). For mixed-signal systems, system-level, and behavioral modeling NL5 uses simple basic digital, function, C-code, and DLL components. Practically all parameters of NL5 components can be set to positive, negative, zero, or infinity value.
Verilogger Extreme is a newer, compiled-code simulator that is Verilog-2001 compliant and much faster than Pro. Verilog-XL: Cadence Design Systems: V1995: The original Verilog simulator, Gateway Design's Verilog-XL was the first (and only, for a time) Verilog simulator to be qualified for ASIC (validation) sign-off.
As subsequent loops around the first ring bring the light to the resonance condition of the second ring, the two rings will be coupled together and the light will be passed into the second ring. By the same method, the light will then eventually be transferred into the bus output waveguide. Therefore, in order to transmit light through a double ...
Cider [7] adds a numerical device simulator to ngspice. It couples the circuit-level simulator to the device simulator to provide enhanced simulation accuracy (at the expense of increased simulation time). Critical devices can be described with their technology parameters (numerical models), all others may use the original ngspice compact models.
CircuitLogix simulates analog, digital, and mixed analog-digital circuits. The simulator first divides the circuit into analog and digital portions. The analog circuitry is simulated with the time-step driven SPICE engine, while the digital parts are simulated separately with an event-driven simulation engine.
