Free・No Limits
Free・No Limits
LTspice® is a free electronic circuit simulator provided by semiconductor manufacturer Analog Devices. It does not have a limit on the number of components or nodes.
高速シミュレーション
Powerful and Fast
LTspice® makes simulating switching regulators extremely fast compared to normal simulators, allowing users to view waveforms for most switching regulators in just a few minutes.
使いやすいGUI
Sophisticated GUI
LTspice® is an easy-to-understand electronic circuit simulator which allows the user to view not only numerical data but also graphical waveforms for simulation results.

Minimize Design Respins and Speed Up Your Simulations by Linking with LTspice

Quadcept allows the user to generate a netlist for the SPICE simulator and run a simulation with LTspice without having to rewrite your circuit design for simulation.

High Performance Circuit Simulation

Analyze your circuit from multifaceted perspectives

Transient

Perform a non-linear, time-domain simulation.

Analysis

Compute the small signal AC behavior of the circuit linearized about its DC operating point.

DC Sweep

Compute the DC operating point of a circuit while stepping in dependent sources and treating capacitances as open circuits and inductances as short circuits.

Noise

Perform a stochastic noise analysis of the circuit linearized about its DC operating point.

DC Transfer

Find the DC small-signal transfer function.

DC op pnt

Compute the DC operating point treating capacitances as open circuits and inductances as short circuits.

You need to download LTspice separately.
LTspice allows you to simulate various types of circuits, but there may be some differences between the simulated and actual behavior because each simulation model uses standard values for each parameter. Please note this when you run simulations.
