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.
NI Multisim (formerly MultiSIM) is an electronic schematic capture and simulation program which is part of a suite of circuit design programs, [1] along with NI Ultiboard. Multisim is one of the few circuit design programs to employ the original Berkeley SPICE based software simulation. [ 2 ]
LM3914 driving an LED bargraph display LM3915 IC in DIP-18 package. The LM3914 is an integrated circuit (IC), designed by National Semiconductor in the late 1970s, used to operate displays that visually show the magnitude of an analog signal. [1] It can drive up to 10 LEDs, LCDs, or vacuum fluorescent displays on its outputs. The linear scaling ...
In most cases a comparator is implemented using a dedicated comparator IC, but op-amps may be used as an alternative. Comparator diagrams and op-amp diagrams use the same symbols. A simple comparator circuit made using an op-amp without feedback simply heavily amplifies the voltage difference between Vin and VREF and outputs the result as Vout.
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 have on the output. They also typically contain extensive model and device libraries.
It is designed to run on 32-bit or 64-bit editions of Windows 7, 8, 8.1, 10, and macOS 10.9+. [2] Summary of major changes from LTspice IV to LTspice XVII are: Add 64-bit executables. [6] Add Unicode characters in schematics, netlists, plot. [6] Add device equations for IGBT, diode soft recovery, arbitrary state machine. [6]

NI Ultiboard, formerly ULTIboard, is an electronic printed circuit board (PCB) layout program which is part of a suite of circuit design programs, along with NI Multisim. One of its major features is the real time design rule check , a feature that was only offered on expensive work stations in the days when it was introduced.
