Hello Sounndarrajan.V,

Try to use place junction to connect the component.

Sometimes, when you connect a wire, the end wire part would be incomplete. So placing a junction ensures the connection is present between the components.

Your second query about the eSim libraries:

You can add libraries manually,

Preferences--> Component Libraries --> Choose from c: user/share/Kicad/Library and then press add.

thank you i have added libraries and resolved.

i'm getting ErrType(3) error and its hard to understand what the error actually is.

please help to fix this problem

Hello Sounndarrajan,

Please give the error statement along with the type.

Usually the ErrType(3) is: pin connected to some other pins but no pin to drive it.

Then, you need to add PWR_FLAG to indicate that these are power ports. For any power ports used, you need to add PWR_FLAG.

All the best...

Yes,this what the error showing. It is shown near the ground and vcc connection.

There also pwr_flag should be add...???

Hello,

Yes, for any power source (Vcc, Gnd) you need to add PWR_FLAG to indicate these are power ports.

Thank you, Gloria

I'll try and tell the results....

For plotting the output we should use which plot...??

One more doubt

While converting form kicad-ngspice simulation it shows "unknown component lm741 is used".

How to fix this.

Hello Sounndarrajan,

Since you are using Op-amp (lm741). Try to add component form eSim_Subckt devices.

In eSim_Subckt devices, it is referred as ua741.

* Remember, once you convert kicad-ngspice, don't forget to add the path of subcircuitused.

For output plot: you can choose component fromeSIm_Plot, based on what kind of output you need to plot (log, v, i, phase).

How to add path to my file.

19-11-17, 4:12 p.m. sounndarrajan.v

Hello,

When you do Kicad-Ngspice conversion, along with analysis, source details, there is a Subcircuits tab.
Click on it. You will get add button.
Click on it and explore the available sub-circuits.

i am using opamp in my project.

while converting Kicad-Ngspice conversion it shows unknown component lm741.

how to fix it.??

Hello,

Like I said, most of the components of kicad, will not be recognized in ngspice.

It is preferable to use thecomponentsnamed under eSIm.

If you are using Opamp-741, then you have to choose it from eSim-Subckt option.

In eSim-Subckt is is labelled as ua741. You can choose that.

Regards,

Gloria
