Ltspice - divided two plots from different run simulations

In summary, the topic discusses the process of dividing two plots from different simulation runs in LTspice, a circuit simulation software. It involves using the software's features to overlay or compare data from separate simulations, allowing for analysis of varying circuit behaviors or parameters under different conditions. This technique enhances the understanding of circuit performance and aids in troubleshooting and design optimization.

Hi,
I have a plot of v(onoise) of my circle using noise simulation.
I also have my V(output) from my ac frequency analysis. How do i divide between the graphs?

Maybe @Baluncore can advise? He does more LTSpice than most of us. There are also online guides.
I doubt that it supports simultaneous displays from different simulations. You'll probably have to export the data to another graphing application.

Welcome to PF.
I would suggest you first join the LTspice group, then search and ask your specific question there.

FAQ: Ltspice - divided two plots from different run simulations

What is LTspice and why would I want to divide two plots from different simulations?

LTspice is a powerful, free simulation software used for electronic circuit design and analysis. Dividing two plots from different simulations can help you analyze the relative performance of two circuits or configurations, allowing you to visualize how one circuit's output behaves in relation to another's under varying conditions.

How can I export data from LTspice for comparison?

You can export data from LTspice by right-clicking on the plot you want to export and selecting "Export Data." This will allow you to save the data in a text format that can be easily imported into other software for further analysis or plotting.

Is it possible to overlay two different simulation results in LTspice?

Yes, you can overlay two different simulation results in LTspice by running both simulations and then using the "Add Trace" feature to select the outputs you want to compare. This allows you to visualize both results on the same plot for easier comparison.

How do I perform mathematical operations on simulation results in LTspice?

In LTspice, you can perform mathematical operations on simulation results by using the 'Add Trace' feature. You can enter expressions like V(out1)/V(out2) to divide the outputs of two different simulations directly in the plot window.

Can I save the divided plot as an image for presentation purposes?

Yes, you can save the divided plot as an image by right-clicking on the plot and selecting "Save Plot as Image." You can choose various formats such as PNG or BMP, which are suitable for presentations and reports.
