In particular, forintegrated circuits, the tooling (photomasks) is expensive, breadboards are impractical, and probing the behavior of internal signals is extremely difficult. Therefore, almost all IC design relies heavily on simulation. Some electronics simulators integrate a schematic editor, a simulation engine, and on-screen waveforms , and make “what-if” scenarios easy and instant. They also typically contain extensive model and device libraries. These models typically include IC specific transistor models such as BSIM, generic components such as resistors, capacitors, inductors and transformers, user defined models (such as controlled current and voltage sources, or models in Verilog-Aor VHDL-AMS).ģ.Introduction of some Electronic Circuit simulation ToolĮasyeda is an online schematic capture, Spice simulation ,PCB layout Tools which provides one-stop shop for Electronic Projects.Įasyeda provides abundant examples of Electronic Circuit Simulation, which help you understand more of Electronics.įast, accurate simulation of electronic circuits is essential because it provides the information needed to perform accurate analysis of circuit behavior. SPICE simulators are used to verify that analog and mixed-signal circuits will yield the expected outputs. A schematic netlist file and circuit input values are fed to the SPICE software, which simulates the circuit's behavior for a specified length of time. CircuitLogix allows for the observation of voltage and current levels at any circuit node as they change with frequency and time. It allows for obtaining accurate results even when simulating complex circuits where hierarchical blocks are reused. The CircuitLogix simulation engine is based on Berkeley SPICE, and contains a GUI to make circuit design easier and more efficient. The CircuitLogix 32-bit SPICE engine is interactive, allowing, for example, the frequency of sources to be changed, potentiometers adjusted, and switches thrown during simulation.

The SPICE engine is fully integrated with the schematic capture and waveform tools CircuitLogix passes schematic edits to the simulator automatically while running. Components such as fuses, LEDs and controlled switches are automatically updated in the schematic as the simulation runs.ĬircuitLogix simulates analog, digital, and mixed analog-digital circuits. 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 simulator automatically performs signal conversion, it is possible to connect any analog or digital part to any other.
