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.
For mixed signal circuit simulation ngspice allows users to create a user-defined node definition file (UDN) of a new device model interface. The implementation of the node is created and simulated by using C language with macros which is compiled by standard C/C++ compilers. New models can be added to the simulator using:
LTspice is a SPICE-based analog electronic circuit simulator computer software, produced by semiconductor manufacturer Analog Devices (originally by Linear Technology). [2] It is the most widely distributed and used SPICE software in the industry. [6]
123D Circuits In-browser circuit design and PCB layout tools. Created by Autodesk, it is free to use, zero-install and web based. There's a limited library of components to use. There are 3 drawing modes: schematics, PCB and breadboard diagram. The PCB editor does not do automatic routing.
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 ...
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 ...
CVC is a Verilog HDL compiled simulator. CVC has the ability to simulate in either interpreted or compiled mode. Source code is available under a Perl style artistic license. TkGate: GPL2+ Jeffery P. Hansen: V1995: Event driven digital circuit editor and simulator with tcl/tk GUI based on Verilog. Includes Verilog simulator Verga. Verilator
Since ports are only attached to node 1 and node 4, nodes 2 and 3 need to be removed through Kron reduction. The table below shows the reduced Y parameter matrix of the Chebyshev filter example simulation after nodes 2 and 4 are eliminated. The nodes of the reduced table are renumbered to 1 and 2.
