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.
EasyEDA is a web-based electronic design automation (EDA) tool suite that enables hardware engineers to design, simulate, share (publicly and privately) and discuss schematics, simulations and printed circuit boards, and to create a bill of materials, Gerber files, pick and place files and documentary outputs in the file formats PDF, PNG, and SVG.
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)

Behavioral simulation – high-level simulation of a design's architectural operation, accurate at cycle-level or interface-level. Hardware emulation – Use of special purpose hardware to emulate the logic of a proposed design. Can sometimes be plugged into a system in place of a yet-to-be-built chip; this is called in-circuit emulation.
Using a PMU, it is simple to detect abnormal waveform shapes. A waveform shape described mathematically is called a phasor.. A phasor measurement unit (PMU) is a device used to estimate the magnitude and phase angle of an electrical phasor quantity (such as voltage or current) in the electricity grid using a common time source for synchronization.
In power engineering, the power-flow study, or load-flow study, is a numerical analysis of the flow of electric power in an interconnected system. A power-flow study usually uses simplified notations such as a one-line diagram and per-unit system, and focuses on various aspects of AC power parameters, such as Voltage, voltage angles, real power and reactive power.
