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.
Schematic of an AGC used in the analog telephone network; the feedback from output level to gain is effected via a Vactrol resistive opto-isolator.. Automatic gain control (AGC) is a closed-loop feedback regulating circuit in an amplifier or chain of amplifiers, the purpose of which is to maintain a suitable signal amplitude at its output, despite variation of the signal amplitude at the input.
LTspice provides schematic capture to enter an electronic schematic for an electronic circuit, an enhanced SPICE type analog electronic circuit simulator, and a waveform viewer to show the results of the simulation. [2] Circuit simulation analysis based on transient, noise, AC, DC, DC transfer function, DC operating point can be performed and ...
Mixed-mode simulation is handled on three levels: with primitive digital elements that use timing models and the built-in 12 or 16 state digital logic simulator, with subcircuit models that use the actual transistor topology of the integrated circuit, and finally, with inline Boolean logic expressions.
SPICE [5] is the origin of most modern electronic circuit simulators, its successors are widely used in the electronics community. Xspice [ 6 ] is an extension to Spice3 that provides additional C language code models to support analog behavioral modeling and co-simulation of digital components through a fast event-driven algorithm.
TINA software is available in installable and cloud-based versions. Feature versions exist for use in industry [6] and for educational use. [2] [7] TINA allows simulation, design, and real-time testing of hardware description language (HDL), such as VHDL, VHDL-AMS, Verilog, Verilog-A, Verilog-AMS, SystemVerilog and SystemC and for microcontroller (MCU) circuits, [2] as well as mixed electronic ...
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.
Oregano is a graphical software application for schematic capture and simulation of electrical circuits. The actual simulation is performed by the SPICE, Ngspice or Gnucap engines. It is similar to gEDA and KTechlab. It makes use of GNOME technology and is meant to run on free Unix-like operating systems such as Linux, FreeBSD et al.
