How do I make LTspice simulate faster?
To measure the effects of your changes, review the simulation time in the LTspice error log (Ctrl + L). Reduce the time required for switch mode power supply (SMPS) simulation by shortening the voltage ramp of the output by changing the value of the soft-start capacitor.
How do I update my LTspice?
At any time, a user can manually update LTspice by choosing “Sync Release” from the “Tools” pulldown menu. From the “Help” pulldown menu, “Show Change Log” displays a list of every SPICE model and software change since LTspice XVII was first released.
How to reduce the simulation time In LTspice?
Reduce the Amount of Transient Analysis Data. Normally, LTspice transient analysis starts at time = 0. You can edit the .trans simulation command’s “Time to start saving data” to delay saving until a later time of interest, thus decreasing your overall simulation time.
What should time be for LTspice transient analysis?
Normally, LTspice transient analysis starts at time = 0. You can edit the.trans simulation command’s “Time to start saving data” to delay saving until a later time of interest, thus decreasing your overall simulation time. Of course this assumes you do not need the initial data points, which are not saved.
Why does LTspice use a compressed binary file format?
To maintain fast simulation speed, LTspice uses a compressed binary file format that allows additional simulation data to be quickly appended on the fly. However, once the simulation has completed, this format is non-optimal for waveform viewing.
How to speed up waveform plotting In LTspice?
To speed up waveform plotting after the simulation is complete, convert the file to an alternate, “Fast Access,” format. Click in the waveform window and choose Files > Convert to Fast Access. This can also be implemented using the .option fastaccess directive:
