End-of-life, no longer updated; historically important, because many analog simulators are based on this project Xyce [17] Sandia National Laboratories: 2023 Windows, macOS, Linux * * Backend simulator, supports parallel simulation on Linux and macOS, can solve huge circuits
LIFTING (LIRMM Fault Simulator) is an open-source simulator able to perform both logic and fault simulation for single/multiple stuck-at faults and single event upset (SEU) on digital circuits described in Verilog. OSS CVC: Perl style artistic license: Tachyon Design Automation: V2001, V2005: CVC is a Verilog HDL compiled simulator.
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 have on the output.
The simulator first divides the circuit into analog and digital portions. The analog circuitry is simulated with the time-step driven SPICE engine, while the digital parts are simulated separately with an event-driven simulation engine. The CircuitLogix digital engine was developed directly in .NET, faster than SPICE macros. Because the ...
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]
Logic simulation is the use of simulation software to predict the behavior of digital circuits and hardware description languages. [ 1 ] [ 2 ] Simulation can be performed at varying degrees of physical abstraction , such as at the transistor level , gate level , register-transfer level (RTL), electronic system-level (ESL), or behavioral level.
VHDL analyzer, compiler, and simulator. [12] Icarus Verilog *BSD, Linux, Mac: GPL-2.0-or-later: Verilog simulator Verilator: Posix: LGPL-3.0-only or Artistic-2.0: Verilator is the fastest free Verilog HDL simulator. It compiles synthesizable Verilog into cycle accurate C++ or SystemC code following 2-state synthesis (zero delay) semantics.
Logic simulation is the use of a computer program to simulate the operation of a digital circuit such as a processor. [4] This is done after a digital circuit has been designed in logic equations, but before the circuit is fabricated in hardware.
