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.
General purpose, includes 2D and 3D magnetics solvers, both static and harmonic. 3D solver is based on the Whitney AV formulation of Maxwell's equations. VSimEM: Commercial Yes Yes Yes Yes Yes Automatic, variable mesh FDTD, PIC, finite volume: Simulating electromagnetics, and electrostatics in complex dielectric and metallic environments.
A major application of current loops is the industry de facto standard 4–20 mA current loop for process control applications, where they are extensively used to carry signals from process instrumentation to proportional–integral–derivative (PID) controllers, supervisory control and data acquisition (SCADA) systems, and programmable logic ...
Sim4Life - 3D computer-aided-design-based electromagnetic (EM) simulation platform: Sim4Life, which includes all elements of the now discontinued SEMCAD platform developed by Schmid and Partner Engineering AG, combines classical technical computer-aided-design tools with multi-physics solvers, computational human phantoms, medical-image-based ...
Microwave Office - RF/microwave circuit simulation, APLAC - Harmonic balance solver for nonlinear, frequency domain circuit simulation; Analog Office - analog/RFIC simulation; Visual System Simulator (VSS) - system level communication/radar simulator; EM solvers: AXIEM (3D planar electromagnetic simulator) – 3D planar, Method of Moments
There are modules that enable motor drive simulation, digital control, and the calculation of thermal losses due to switching and conduction. [9] There is a renewable energy module which allows for the simulation of photovoltaics (including temperature effects), batteries, supercapacitor , and wind turbines.
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.
Simulation data can be represented in various types of diagrams, including Smith-Chart, Cartesian, Tabular, Polar, Smith-Polar combination, 3D-Cartesian, Locus Curve, Timing Diagram and Truth Table. The documentation offers many useful tutorials (WorkBook), reports (ReportBook) and a technical description of the simulator.
