Description

How to use some of the more advanced features of EasyEDA to make measurements of your simulation.

Thanks to ngspice, EasyEDA has some powerful features for controlling simulations and carrying out calculations on data from them.

This Project folder showcases some of the more frequently used techniques.

To run the simulation from the view window, click on the little green pencil in the upper right, then when the schematic opens in EasyEDA, press:

Ctrl+R

and Save - if prompted - to Anonymous Files or your own project if you are logged in, then press:

CtrL+R

again.

Then do:

Green Man > Simulation Results...

and scroll down to see the measure statement results.

For detailed information on the syntax and usage of meas statements please refer to:

http://ngspice.sourceforge.net/docs/ngspice-manual.pdf#subsection.17.5.37

in:

http://ngspice.sourceforge.net/docs/ngspice-manual.pdf#chapter.17

Note that the 'param' and 'par(expression)' forms referred to in:

http://ngspice.sourceforge.net/docs/ngspice-manual.pdf#subsection.15.4.9

and:

http://ngspice.sourceforge.net/docs/ngspice-manual.pdf#subsection.15.4.10

are replaced by the 'let' statement described in:

http://ngspice.sourceforge.net/docs/ngspice-manual.pdf#subsection.17.5.33 This project is part of the EasyEDA spice simulation learning resource.
