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.
Pulse-width modulation (PWM), also known as pulse-duration modulation (PDM) or pulse-length modulation (PLM), [1] is any method of representing a signal as a rectangular wave with a varying duty cycle (and for some methods also a varying period). PWM is useful for controlling the average power or amplitude delivered by an
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]
Aeolus-DS is a part of Aeolus simulator which is designed to simulate mixed signal circuit. Aeolus-DS supports pure Verilog simulation. HiLo Teradyne Used in 1980s. Incisive Enterprise Simulator ('big 3') Cadence Design Systems: VHDL-1987,-1993,-2002,-2008, V2001, SV2005, SV2009, SV2012, SV2017
PLECS (Piecewise Linear Electrical Circuit Simulation) is a software tool for system-level simulations of electrical circuits developed by Plexim. [1] It is especially designed for power electronics but can be used for any electrical network.
It is analogous to pulse-width modulation (PWM), in which the magnitude of an analog signal is encoded in the duty cycle of a square wave. Unlike PWM, in which the width of square pulses is varied at a constant frequency, PFM fixes the width of square pulses while varying the frequency.
If the supply has a DC output, its time base is of no importance in deciding when to pulse the supply on or off, as the value that will be pulsed on and off is continuous. PFC differs from pulse-width modulation (PWM) in that it addresses supplies that output a modulated waveform, such as the sinusoidal AC waveform that the national grid outputs.
PSTricks is a circuit drawing package implemented with PSTricks , which allows TeX users to "code" figures with the aid of PostScript. Packages like pst-eps or preview allow for easy production of images with tight bounding boxes. Advantages: Full use of PostScript (e.g., colors, bitmaps, vectors, etc.).
