Windows, macOS, Linux VHDL: Fork of Logisim (development ended in 2011) [6] LTspice: Analog Devices: 2024 Windows, macOS, POL: Very popular, updated often [7] Originally created at Linear Technology. Micro-Cap: Spectrum Software: 2021 Windows PLD expressions End-of-life, no longer updated; was commercial software: QSPICE [8] Qorvo: 2024 Windows ...
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
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.
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 ...
[1] [7] [12] It is designed to run on Windows 2K, XP, Vista, 7 with a processor that contains a minimum instruction set similar to a Pentium 4 processor. [13] Though IV is still available for download, it is no longer maintained. LTspice was originally called SwitcherCAD, but that name was removed when IV was released. [1]
EasyEDA is a free, zero-install, Web and Cloud-based EDA tool suite, integrating powerful schematic capture, mixed-mode circuit simulator and PCB layout in a seamless cross-platform browser environment. It has some nice features: Export. PCB netlist in Altium Designer KiCad PADS; Spice netlist; WaveForm simulation plot data (in CSV format)
PSIM is an Electronic circuit simulation software package, designed specifically for use in power electronics and motor drive simulations but can be used to simulate any electronic circuit. Developed by Powersim, PSIM uses nodal analysis and the trapezoidal rule integration [2] as the basis of its simulation algorithm. PSIM provides a schematic ...
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.
