As subsequent loops around the first ring bring the light to the resonance condition of the second ring, the two rings will be coupled together and the light will be passed into the second ring. By the same method, the light will then eventually be transferred into the bus output waveguide. Therefore, in order to transmit light through a double ...
The most well known analog simulator is SPICE. Probably the best known digital simulators are those based on Verilog and VHDL . 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 ...
Non-linear components are represented as piecewise-linear, or as a function (simulated with one step delay). For mixed-signal systems, system-level, and behavioral modeling NL5 uses simple basic digital, function, C-code, and DLL components. Practically all parameters of NL5 components can be set to positive, negative, zero, or infinity value.
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.
Cider [7] adds a numerical device simulator to ngspice. It couples the circuit-level simulator to the device simulator to provide enhanced simulation accuracy (at the expense of increased simulation time). Critical devices can be described with their technology parameters (numerical models), all others may use the original ngspice compact models.
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]
SPICE OPUS is a free general purpose electronic circuit simulator, developed and maintained by members of EDA Group, University of Ljubljana, Slovenia. [1] It is based on original Berkeley ’s SPICE analog circuit simulator and includes various improvements and advances, such as memory-leak bug fixes and plotting tool improvements.
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 ...
